Slowly, stars will fizzle out, turning night skies black. [17] It could, in the absence of dark energy, occur only under a flat or hyperbolic geometry. We cannot say that these theories were wrong; perhaps it would be truer to say they . Then surely some unknown force is working against the force of gravity. Instead, it gets very close and is then repelled by a force similar to the one that repels a ball when you bounce it off the floor. It would just be that one instant in time. While matter becomes less dense as the Universe expands, diluting as . > Ah, the age-old notion that the universe always has beenand always will be. https://en.wikipedia.org/w/index.php?title=Ultimate_fate_of_the_universe&oldid=1121497410, This page was last edited on 12 November 2022, at 16:16. This bubble will expand in all directions at the speed of light and wipe out everything it touches. In the special case of phantom dark energy, which has supposed negative kinetic energy that would result in a higher rate of acceleration than other cosmological constants predict, a more sudden big rip could occur. [16] This scenario, in combination with the Big Rip scenario, is gaining ground as the most important hypothesis. (1) Edwin Hubble discovered that the universe was . This theory states that when the Universe gets to a certain size, it will begin contracting. In this oscillating universe theory, our universe could be the first universe in a series, or it could be the 400th universe. If understood, we could be more sure, of what is going to happen. [24] Therefore, quantum mechanics has given rise to an alternative version of the Big Bang theory, specifically that the universe tunneled into existence and had a finite density consistent with quantum mechanics, before evolving in a manner governed by classical physics. Dark energy is an expansion-dominating cosmological constant. Sign up and stay up to date with our daily newsletter. This is the default option given the best data we have today. In the television series Red Dwarf episode "Backwards", the crew visit a planet which everyone is doing things in reverse although the crew do things forward like we do now. If you use enough energy, the string will break. [8], If They had to change their names somewhere in between for unknown reasons but I believe these two movies take . The Big Bounce is an additional step to the Big Crunch, in that once everything has contracted back into a singularity, the whole thing starts again, a new Big Bang. In 1927, Georges Lematre set out a theory that has since come to be called the Big Bang theory of the origin of the universe. In contrast, the planck era describes the universe's beginning, and is the earliest meaningful time. Observations made by Edwin Hubble during the 1930s1950s found that galaxies appeared to be moving away from each other, leading to the currently accepted Big Bang theory. According to this theory, gravity will eventually cause this expansion to slow to the point where it halts and begins to contract instead. Here are the top theories about the ultimate fate of the universe. 2. The scariest part of this theory is that, while most of these scenarios take place long after the stars have burned out and nothing is left anyway, the Big Rip is scheduled to happen (at the earliest estimate) in another 16 billion years. The universe is expanding and once it gets to a certain size, the energy will have run out and dissipate. The Big Crunch is based on Einstein's Theory of General Relativity. Alexander Friedmann proposed several solutions in 1922, as did Georges Lematre in 1927. The universe will be in a state of equilibrium, and these particles will bounce off of one another without exchanging energy. We know that the farthest parts of the universe are accelerating away and the closer we get to us, the less so, with the exception of Andromeda which is heading toward us, but this may be an anomaly (chaos theory.) All that matter expanding outward at the edges of the universe is being affected by our universes gravity. The universe will come to a standstill. This suggests that the universe began very dense about 13.787 billion years ago, and it has expanded and (on average) become less dense ever since. But what if time lost momentum and just froze? Just the same instant in time. It will always be here. Lets discuss this briefly. According to a popular theory, most matter in the universe is orbiting black holes. We are currently in the Stelliferous Era, the age of the stars. , then the geometry of the universe is flat: as in Euclidean geometry, the sum of the angles of a triangle is 180 degrees and parallel lines continuously maintain the same distance. As the gravitational force weakens with expansion, the magnitude of this force becomes stronger. As for whether you'd do the same thing again, I couldn't possibly say. Starting in 1998, observations of supernovas in distant galaxies have been interpreted as consistent[6] with a universe whose expansion is accelerating. This is also a paradox - humanity are special because The Doctor saves them, but he saves . They could start in Big Bangs. According to one version of the Big Bang theory of cosmology, in the beginning the universe was infinitely dense. These are called, respectively, the flat, open and closed universes. There is no synchronicity between the two eras. This is based on the Big Bang theory, which is the most widely accepted theory of the universe's origins. Hence cosmologists aimed to determine the fate of the universe by measuring Many current theories suggest dark energy is a cosmological constant, a kind of uniform energy that exists throughout space. Ah, the age-old notion that the universe always has beenand always will be. The expansion speed of cosmic objects like galaxies, clusters, etc. The theory does, however, require that the acceleration of the expansion either remains constant or slows down. What if there were no more moments? In a finite universe, these black holes would eventually devour most of the matter, and we would be left with a dark universe. The current Hubble constant defines a rate of acceleration of the universe not large enough to destroy local structures like galaxies, which are held together by gravity, but large enough to increase the space between them. In the Big Freeze scenario, the universe will grow so big that the supply of gas will be too thin for stars to form. This unknown energy is called dark energy. Matter will still be there, but in particle form, and its motion will be totally random. {\displaystyle \Omega >1} The paper, published in the Journal of High Energy Physics in May, puts forward that the Universe is far less complex than current multiverse theories suggest.. It's based around a concept called eternal inflation, first introduced in 1979 and published in 1981.. After the Big Bang, the Universe experienced a period of exponential inflation.Then it slowed down, and the energy converted into . What are the 7 theories of the origin of the universe? 1 Our current understanding is that time and space began during the Big Bang , when a subatomic, ultra-hot and super-dense point . {\displaystyle \Omega <1} Many theories have been given so far on how our universe will be destroyed. With an infinite amount of time, anything that could possibly happen has a 100 percent probability of happening. [15], The Big Freeze (or Big Chill) is a scenario under which continued expansion results in a universe that asymptotically approaches absolute zero temperature. If we extrapolate that to our universe, we wind up with all of the matter evenly dispersed throughoutin a cold, dark, boring mist. According to Professor Brian Cox in his Wonders of series, he says there are not enough atoms in the universe to represent the amount of years left until the Universe has completely gone. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the "Big Freeze" scenario below. And we will take that moment as the death of this universe. As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. In this scenario in 22 billion years, all things will be torn apart, including planets, atoms, and even time. The theories of the universe timeline may differ from the reality, but the fact remains that the evolution of the universe is a constant process. A steady increase in the Hubble constant to infinity would result in all material objects in the universe, starting with galaxies and eventually (in a finite time) all forms, no matter how small, disintegrating into unbound elementary particles, radiation and beyond. If But the surprising thing is that they do not slow down. Eventually these too will evaporate as the universe gets ever colder, leaving nothing behind. {\displaystyle \Omega } Eventually, the acceleration speeds up so much that, like the Enterprise at warp factor nine, it cant take any more and rips itself apart into nothingness. 2.4 Number Four: The End of Time. While Newton's theory explains the behavior of objects at relatively small cosmic scales such as why we don't fall off the Earth and our planet stays rotating around the sun going bigger gets problematic. Youd never grow old. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Then something caused it to explode. is equal to, less than, or greater than How are galaxies moving away faster than light? With dark energy, the expansion rate of the universe initially slows down, due to the effects of gravity, but eventually increases, and the ultimate fate of the universe becomes the same as that of an open universe. That's 3 or 4 . Today's two primary theories of physics both hold predictions for the end of the universe. This article is copyrighted by IBTimes.co.uk, the business newsleader, IBT UK Morning Brief - Let the best of International News come to you. Eventually, it will stop expanding and start collapsing into itself. Galaxies drift apart like forlorn lovers, and the all-encompassing night between them becomes wider and wider. Now, its very likely that we just dont have the understanding of physics to accurately describe this phenomenon yet, but its certainly a scary prospect. The Big Freeze. The sum of the angles of a triangle exceeds 180 degrees and there are no parallel lines; all lines eventually meet. They make it to the furthest reaches of the universe, surviving until the end. The theory states that continued expansion of the universe will cause the fabrics of the universe to tear apart. There's no register feature and no need to give an email address if you don't need to. If we try to calculate probabilities in a multiverse (where there are infinite universes, each just a little different), we run into the same problem as the infinite-time universe: Everything has a 100 percent chance of occurring. None of these theoretic endings for the universe are certain. The Universe is only 13.5 Billion Years old, it still has the vast part of his life ahead of us. The theory is known as the Steady State Theory which says matter lost is replaced by new matter. If anything is eternal, its surely time. When I say long, I really mean long, there is not enough bandwidth to say how long it might be. It is also possible that all structures will be destroyed instantaneously, without any forewarning. If the theory of inflation is true, the universe went through an episode dominated by a different form of dark energy in the first moments of the Big Bang, but inflation ended, indicating an equation of state far more complex than those assumed so far for present-day dark energy. Even though time itself could run out in other universes, in a multiverse, new universes are being born all the time. The current scientific consensus of most cosmologists is that the ultimate fate of the universe depends on its overall shape, how much dark energy it contains and on the equation of state which determines how the dark energy density responds to the expansion of the universe. In this model, things arent really destroyed, just recycled.. The Universe has no beginning and no end, the Universe is here to stay. It says the expansion of the universe (from the Big Bang) will not continue forever. If this happens repeatedly, it creates a cyclic model, which is also known as an oscillatory universe. Imagine the same scenario: Gravity slows the expansion of the universe and condenses everything back into one single point. [citation needed]. 2.3 Number Three: Massive Black Holes. And just like we want to know what happens when we die, science has asked how the universe will end for as long as man has been able to think about such concepts. Here is a guide to the different theories. But it doesnt matter: In a multiverse, our universe is just one of many. You guessed it - it is expansion. 2.1 Number One: Big Crunch Theory. A black, empty, dark and cold space is what remains according to the theory of heat death. [18] Over infinite time, there would be a spontaneous entropy decrease by the Poincar recurrence theorem, thermal fluctuations,[19][20] and the fluctuation theorem. Okay so 13 going on 30 and the Adam Project both star Jennifer Garner and Mark Ruffalo! , or equivalently the rate at which the expansion was decelerating. About Press Copyright Contact us Creators Advertise Press Copyright Contact us Creators Advertise This theory, which recently hit headlines across the globe, says that a type of phantom dark energy will get stronger over time. These three adjectives refer to the overall geometry of the universe, and not to the local curving of spacetime caused by smaller clumps of mass (for example, galaxies and stars). There are those who believe that there will be no end to the Universe, that the Universe will continue for every. The theoretical scientific exploration of the ultimate fate of the universe became possible with Albert Einstein's 1915 theory of general relativity. In this theory, the force of that rapid compression is enough to start off another big bang, and the universe starts again. As the universe expands at an ever increasing rate, eventually it will not be able to withstand the speeds and will rip itself apart individual atoms will disassemble themselves into radiation and unbound elementary particles. This is true for school, for work, for life, for Earth, and for the universe as well. If you give an email address, you may receive an email notifying you when someone else has added a comment to the same page. And according to the physics, sometime in the next 3.7 billion years, well cross that time barrier, and the universe will end for us. They are all named have Big in their name to signify how much it will affect and also a nod to the the big bang which started it all. Many have explained it in many ways. When this happens, at some point in the universe, a bubble will appear. Thanh notes that, while there are many theories about how humankind and the universe as a whole will end, one fact is certain: the end is coming, one way or another. Freeze is more appropriate as the universe will get really really cold and not just a lower temperature. Just as the Big Bang started as a cosmological expansion, this theory assumes that the average density of the universe will be enough to stop its expansion and the universe will begin contracting. Conversely, a negative cosmological constant, which would correspond to a negative energy density and positive pressure, would cause even an open universe to re-collapse to a big crunch. There are several possible solutions to the equations of general relativity, and each solution implies a possible ultimate fate of the universe. {\displaystyle 1} = What is dark energy that is not well understood? There is a strong consensus among cosmologists that the shape of the universe is considered "flat" (parallel lines stay parallel) and will continue to expand forever.[2][3]. You can decline to give a name which if that is the case, the comment will be attributed to a random star. The fate of the universe is determined by its density. Rather, it is increasing gradually. General Relativity: The World Ends in Ice. When Einstein found that his general relativity equations could easily be solved in such a way as to allow the universe to be expanding at the present and contracting in the far future, he added to those equations what he called a cosmological constantessentially a constant energy density, unaffected by any expansion or contractionwhose role was to offset the effect of gravity on the universe as a whole in such a way that the universe would remain static. By doing this, the energy density will gradually decrease. Most theories about the end of the world start with the world BIG (see the Big Bounce, the Big Crunch, and even the Big Bang). From the day that all the dense matter blew up (do not worry if you do not . Before discussing the universe's end, let's go into its birth. So, let's assume (I hate that word) there isn't. Our sample consists of a subset of 74 spiral galaxies from the Carnegie-Irvine Galaxy Survey with absolute B-band magnitude MB>19.12 mag and luminosity distance DL25.4 . and in the Adam Project they're married have a son but he's dead. However, if the vacuum is not in its lowest energy state (a false vacuum), it could tunnel into a lower-energy state. > The "how, or if, the Universe started" question is intimately linked to "how, or if, the Universe will end". Take an elastic band, pull it apart as far as you can then let go, it will return back to its former size which in our case will be the singularity in which the Big Bang started from. Ours could end in a Big Crunch, a heat death, a Big Rip, or even a Big Foot (and the shout of we told you so from cryptozoologists would echo into eternity). The fate of the universe may be determined by its density. The idea of the Universe ending in a Big Rip was first postulated in 2003. As the energy density, scale factor and expansion rate become infinite the universe ends as what is effectively a singularity. The Big Bounce is a bit more optimistic in that it says the universe will never really end. One of these ideas (theories) was (at the time) a finite universe that expanded and reached a maximum size and then contracted. Episodes Episode One: The Beginning This episode, exploring theories of how the universe came into being, outlines the realisation of Edwin Hubble that the universe is expanding, and the discovery of the residual radiation that gave weight to the Big Bang theory. With birth rates dropping across the globe, human beings will soon find out whether they can be happy and prosperous with fewer children, or if birth rates will increase as people . [3] Recent observations conclude, from 7.5 billion years after the Big Bang, that the expansion rate of the universe has probably been increasing, commensurate with the Open Universe theory. As the nature of dark energy and dark matter remain enigmatic, even hypothetical, the possibilities surrounding their coming role in the universe are currently unknown. First, the Universe might have what we call positive curvature like a sphere. {\displaystyle \Omega >1} In this case, the Universe is called "closed" and it has a finite size but without a boundary, just like a baloon. Eventually the time that stars existed will be no more than a blink in the eye. They claim the universe did not end. This scenario results in the Universe expanding not with a constant rate of acceleration, but at an increasing rate of . Let me put your minds to rest if you're worried, the End or Fate of the Universe will not occur for a long time. The Big Bounce is somewhat like the Big Crunch but this one is somewhat of a positive theory. More massive black holes would consume the less massive ones, becoming larger, even more massive black holes. In other words, cosmic inflation continues in some parts of the Universe and ceases in others. Love podcasts or audiobooks? [4] In some of these solutions, the universe has been expanding from an initial singularity which was, essentially, the Big Bang. All Rights Reserved. {\displaystyle \Omega =1} {\displaystyle \Omega } However, they also said if this was going to happen, it would have already. This is one of the first concepts that humans created about the nature of the universe, but there is a new spin on this theory that sounds a bit more, well, serious. We could potentially know for sure in the next 20 yearswe have a satellite (the Planck satellite) surveying space for the patterns in background radiation that the prominent theories on the origin of the universe predict. One of the most fascinating things about the universe is how little we really know. That is, as they are moving away from each other, the speed of their moving away is increasing. Newton 2.0. Evidence regarding the Big Bang theory is based on: (1) Hubble's Law, (2) the discovery of the cosmic microwave background, (3) observations of the galaxy formation and evolution, and (4) the distribution of large-scale cosmic structures. All existing stars will eventually burn out leaving only black holes behind. The Big Bounce. Well be left with just particles in a void. You live an infinite time, so anything that is possible is guaranteed to happen (and happen an infinite number of times). Einstein and his contemporaries believed in a static universe. There is not enough grains of sand on this Earth to represent the number of years left till the end of the Universe. [21][22], A related scenario is heat death, which states that the universe goes to a state of maximum entropy in which everything is evenly distributed and there are no gradientswhich are needed to sustain information processing, one form of which is life. The Big Crunch, as you might have guessed, is the Big Bangs opposite. Plasma-filled cosmos. A Black Dwarf is a White Dwarf which has run out of its remaining energy. With dark energy, the expansion not only continues but accelerates. Up until the beginning of the 20th century, the universe was believed to be infinite and ageless. Jamie founded Listverse due to an insatiable desire to share fascinating, obscure, and bizarre facts. As a result, the tendency of all objects in the universe to move away increases. In 1929, Edwin Hubble published his conclusion, based on his observations of Cepheid variable stars in distant galaxies, that the universe was expanding. Based on available observational evidence, deciding the fate and evolution of the universe has become a valid cosmological question, being beyond the mostly untestable constraints of . It actually might not end, its just so far ahead in the future we don't know. The universe follows the same rules as any thermodynamic system, and they all end up the same way: with heat evenly distributed throughout. But its sure to be a far more violent death than the slow heat death most people were expecting. It says the expansion of the universe (from the Big Bang) will not continue forever. One theory describes the end of the universe as the Big Rip. The Big Freeze. It would be a kind of pseudo immortality. All the material in the universe will explode. The result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity). Assuming you were still alive to experience this (in billions of years, long after the Earth is gone), youd never realize anything was amiss. . 2. Surprisingly, the possibilities they describe are very different. At some point, it will be close to zero. This has the potential to fundamentally alter our universe; in more audacious scenarios even the various physical constants could have different values, severely affecting the foundations of matter, energy, and spacetime. A problem with the cyclic universe is that it does not reconcile with the second law of thermodynamics, as entropy would build up from oscillation to oscillation and cause the eventual heat death of the universe[citation needed]. . Based on available observational evidence, deciding the fate and evolution of the universe has become a valid cosmological question, being beyond the mostly untestable constraints of mythological or theological beliefs. There is nothing to say that this has not happened before as its a theory and hard to disprove. 1 The Big Rip theory, despite the fact that it is explaining the end of time and space as we know it, tells us something super critical about the nature of the universe. It says that due to the continuous expansion, all the elements that make up the universe, from atoms to galaxies, will be broken. Such a description seems to be at odds with other more widely accepted theories, especially quantum mechanics and its uncertainty principle. And though it could blow apart and shoot rainbows into the void between universes for all we care, the larger universe will still be there. A name is preferred even if its a random made up one by yourself. Study author Simon Driver said: "The universe will decline from here on in, sliding gently into old age. 7. Jenna (Jennifer) and Matt (Mark) get married at the end of 13 going on 30 right? In the end, eventually the stars will die out, everything will drift apart, and the . [14] However, observations are not conclusive, and alternative models are still possible. If the average density of the universe exactly equals the critical density so that The "Always was" Theory, This is the is the assumption that The Universe is infinite and always has been here and always will be here. We don't know if there is anything to stop it. As the Universe is not perfect, all it takes is one atom to be out of place and things could cause a different future on the bounce back out, your atoms might not end up on Earth next time. The Big Crunch is the opposite of the Big Bang, which explains the origin of the universe. This theory requires the Universe to be either flat or negatively curved. If the primary content of the universe is inert matter, as in the dust models popular for much of the 20th century, there is a particular fate corresponding to each geometry. This theory hinges on the idea that the universe exists in a fundamentally unstable state. A1689-zD1, one of the brightest and most distant galaxies, is 12.8 billion light years away - an extremely far distance in our expanding universe. Since the universe is constantly accelerating, this theory plays on the fact that it will reach infinity at some point. In this model, the universe is cyclical and will continue to expand and contract forever. Its anyones guess. Clearly, theories about the end of the Universe remain untestableit hasn't happened yet, and we can't run an experiment beforehand. As we know, our universe is gradually expanding. Gravity poses a problem. 1.) Similar to the Big Crunch in terms of the universe eventually running out of steam and collapsing on itself, the Big Bounce says that this collapse would eventually cause another Big Bang creating a cyclical effect of endless universes after a singularity is reached. There are three possibilities of the shape of the Universe. A true vacuum exists so long as the universe exists in its lowest energy state, in which case the false vacuum theory is irrelevant. Otherwise, thered be no way to discern one moment from the next. Some new modern theories assume the universe may have a significant amount of dark energy, whose repulsive force may be sufficient to cause the expansion of the universe to continue forevereven if There would be no way to tell. 2.2 Number Two: Heat Death. Big Crunch. The angles of a triangle sum to less than 180 degrees, and lines that do not meet are never equidistant; they have a point of least distance and otherwise grow apart. At the time he published it in 1916, Einstein's theory of general relativity contained an odd term called the cosmological constant. Its a long process, but once we have that radiation pattern, we could have a better understanding of how our universe beganand how it will end. Are We Seeing a New Space Race That is Now Done Between Billionaires? Gravity slows the expansion of the universe and contracts everything back to the center. There was a time (about a century ago) when the theory called General Relativity was born with (at the time) some ideas about how some of the possibilities might be supported by observation. Multiverse and Parallel Universe / Worlds Theory. 3. Current evidence also indicates the universe is not closed[citation needed]. However, there are a number of problems with this theory, one of which being that the universe is expanding at an ever increasing rate. Eventually, wed be left with nothing but gravity wells in an abyss. Eventually black holes will dominate the universe, which themselves will disappear over time as they emit Hawking radiation. But dont worry: The universe will still be there. 3. This theory is about the Universe expanding so much that it rips itself apart. Kier is a writer at Listverse and Cracked.com, and when hes not doing that stuff, hes curled up in the fetal position and worrying about the inevitable heat death of the universe. This theory is about the Universe expanding so much that it rips itself apart. As a result, the planets will move away from each other. In this theory, an unseen force called dark energy is causing the accelerating expansion of the universe that weve observed. Many theories have been given so far on how our universe will be destroyed. The universe could then consist of an infinite sequence of finite universes, with each finite universe ending with a Big Crunch that is also the Big Bang of the next universe. A large part of black hole theory involves the cannibalization of stars or even entire galaxies as they fall into the holes event horizon. Think of it as an alternate universe (though its really the same universe with different properties). Time would just grind to a halt and, according to scientists, Then everything will be frozen, like a snapshot of one instant, forever. But it wouldnt really be forever, since time wouldnt be moving forward at all. The ultimate fate of an open universe is either universal heat death, a "Big Freeze" (not to be confused with heat death, despite seemingly similar name interpretation; see Theories about the end of the universe below), or a "Big Rip"[10] in particular dark energy, quintessence,[11] and the Big Rip scenario[12][13] where the acceleration caused by dark energy eventually becomes so strong that it completely overwhelms the effects of the gravitational, electromagnetic and strong binding forces. It's like a universe inside a universe. Eventually, it will stop expanding and . And at that moment no power can be used. Instead of the singularity of the Big Bang being the start of time itself, time couldve existed before (for an eternity before), and the singularity and resulting bang could have resulted from the collision of two branes (sheet-like structures of space that form on a higher plane of existence). A recent study found the universe is slowly dying, with scientists from International Centre for Radio Astronomy Research in Western Australia finding that the energy produced in some parts of the universe is half of what it was two billion years ago. All . Recent calculations say this will happen in about 22 billion years. The Big Rip Theory End of the universe based on its increasing expansion rate, 10 Famous Historical Beheading Victims Who Were, Top 10 Ways Candles Ruin Your Life And Signal The, 10 Amazing Discoveries At The Edge Of The Universe, 10 Reasons Disney Axed The 'Star Wars' Expanded Universe, The Universe Is Full Of Scary Things. The geometry of the universe is, at least on a very large scale, elliptic. 9. It derives from the oscillatory universe or cyclic repetition interpretation of the Big Bang where the first cosmological event was the result of the collapse of a previous universe. In cosmic terms, this is short compared to what lies ahead for the Universe. As long as . This theory posits that the universe currently exists in a false vacuum and that it could become a true vacuum at any moment. When the Universe started, there was an enormous amount of energy that pushed matter from the centre. At this phase in the universes existence, planets (and theoretically life) will still exist. [25] This is called vacuum decay. Just look at galaxies, which contain almost everything and house supermassive black holes in their centers. No matter how the world ends, scientists feel the need to use the (horribly understated) word big to describe it. Do read the sections on the "early Universe" and alternative theories to the Big Bang before looking at this section. 2.6 Number Six: The Big Rip. And this universe-wide cataclysm could burn them alive, tear them apart, or feed them to the space lions that live between universes. Here's the theory: In the first 10^-43 seconds of its existence, the universe was very compact, less than a million billion billionth the size of a single atom. Nevertheless, new possibilities are arriving with surprising rapidity. The contraction will bring all of that material (planets, stars, galaxies, black holeseverything) back to the center until it becomes that infinitely dense singularity again, wiping out everything. Scientists think it would probably be a lot more boring though, and even postulated that for life to exist, the universe might have to exist on that edge. With a positive cosmological constant, it could also occur in a closed universe. The Big Bang remains the preferred theory of many scientists, supported by two key observations the expansion of the universe and the cosmic microwave background (CMB . Learn on the go with our new app. A universe is anything and everything in existence. ), defined as the average matter density of the universe divided by a critical value of that density. In a multiverse scenario, with infinite universes, these universes may spring in or out of existence. As we make developmental leaps in science and technology, and are able to journey or peer further and further out into the cosmos, both . It maintains that the Universe will expand forever, getting colder and colder. The big crunch is fairly unlikely though, there doesn't appear to be enough mass in the universe to cause it to start contracting on itself, a recent theory of dark energy may be the answer to why the universe appears to be expanding at increasing rates rather than just a constant rate, this would mean the universe could in theory continue to . Corbis. , the geometry of space is closed like the surface of a sphere. In simple terms, this theory states that the universe will continuously repeat the cycle of a Big Bang, followed up with a Big Crunch. Over time, black holes evaporate (lose their mass) because they emit what is called Hawking radiation. So after the last black hole dies, well be left with an even distribution of subatomic Hawking radiation particles. There are also some possible events, such as the Big Slurp, which would seriously harm the universe, although the universe as a whole would not be completely destroyed as a result. Assume we live in a universe that never ends. Thus, if you live forever, the odds of you becoming permanently incapacitated in some way reach 100 percent, and you spend eternity cartwheeling through the blackness of space. To get around this problem, scientists take a section of the universe and just calculate probabilities for it. One unlikely scenarios is that we live life back in reverse, instead of life to death, it'll be death to life. {\displaystyle \Omega } Because the laws of physics dont make sense in an infinite multiverse, the only way this model makes sense is if that boundary is a real, physical boundary that nothing can expand beyond. An important parameter in fate of the universe theory is the density parameter, omega ( Due to the effects of discovered dark energy, it has been assumed until now that our universe will die through a Big Rip or thermal death. All messages will be reviewed before being displayed. In this case, gravity is not strong enough to overcome the expansion, so the universe just keeps on expanding exponentially. [26], However, only a portion of the universe would be destroyed by the Big Slurp while most of the universe would still be unaffected because galaxies located further than 4,200 megaparsecs (13 billion light-years) away from each other are moving away from each other faster than the speed of light while the Big Slurp itself cannot expand faster than the speed of light.[27]. Finally, the entire universe will go dark. Because this messed up a lot of calculations that try to predict outcomes in our universe (like the figures behind dark energy), scientists theorized something else: that time itself must eventually stop. Recent evidence suggests that this scenario is unlikely but has not been ruled out, as measurements have been available only over a short period of time, relatively speaking, and could reverse in the future. There are a number of competing theories of how the universe end, only one can be right but because its so far in the future, we won't know. If the ratio of the dark energy pressure to its energy density, its equation of state, has a value less than -1, the Universe ends in a Big Rip. You can read further into this at Wikipedia. 1 1 However, as the name is meant to imply, very little is currently known about the physics of dark energy. According to the physics, the number of new universes will always outnumber the old ones, so in theory, the number of universes is increasing. If you fix one end of a piece of string to a stationary object and pull the other end. General relativity can be employed to describe the universe on the largest possible scale. , the geometry of space is open, i.e., negatively curved like the surface of a saddle. The Big Bounce is similar to the Big Crunch but far more optimistic. In order to best understand the false vacuum collapse theory, one must first understand the Higgs field which permeates the universe. Sorry, Donald Trump, it cant be infinity, Dark Energy Holds The Ultimate Lesson For Todays Scientific Frontiers, Discovery of First Exoplanet scoops 2019 Nobel Prize for Physics, Astronomers discover a great galactic genocide 11 billion years ago. Which has been going on since the Big Frog. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the "Big Freeze" scenario below. But the universe wouldnt be anything that we could comprehend. This ball of matter then exploded and began to . I am not suggesting you try the elastic band experiment because you will if you do it wrong will HURT yourself. The Big Crunch hypothesis is a symmetric view of the ultimate fate of the universe. In other words, considering the universe is only around 14 billion years old, extrapolating the trends observed in the cosmic history so far to a considerably longer timescale can be criticized as being insufficiently substantiated. This leads to a multiverse scenario, wherein space is broken into bubbles. It is believed by many that the universe began around 13.7 billion years ago. We present an analysis of the pitch angle distribution function (PADF) for nearby galaxies and its resulting black hole mass function (BHMF) via the well-known relationship between pitch angle and black hole mass. The Big Crunch is based on Einstein's Theory of General Relativity. Even without dark energy, a negatively curved universe expands forever, with gravity negligibly slowing the rate of expansion. 1. Theories about the end of the universe. is supposed to slow down after some time under the influence of gravitational force. Whether there is a universe or not, time has to chug on. Among the theories that have been given so far about the destruction of the universe, the notable ones are-, The Big RipThe Big CrunchThe Big FreezeThe Big BounceMultiverse Theory. It also highlights some lesser known theorists including Georges Lematre, who first theorised that there was a big bang, Ralph . This Big Bounce would be very similar to a Big Bang, and would, in theory, produce a new universe. "End of the universe" redirects here. When this happens, it will pull everything in the universe inside it turning into the biggest ever black hole. The geometry of such a universe is hyperbolic.[9]. If you look at the values of quantum physics particles, some suggest that our universe is teetering on the edge of stability. There are two features of the Universe that are key to understanding its fate; they are its density and its shape. One theory of our ultimate end relies on the assumption that this expansion will continue indefinitely until the galaxies, stars, planets, and matter (even the subatomic building blocks that . This one feature makes it almost impossible to know where space ends. This equilibrium also happens with all other forms of energy. These two theories were active contenders until the 1965 discovery, by Arno Penzias and Robert Wilson, of the cosmic microwave background radiation, a fact that is a straightforward prediction of the Big Bang theory, and one that the original Steady State theory could not account for. If the elastic band breaks because you've pulled it too much, then your elastic band universe has destroyed it self in the Big Rip. The truly fascinating thing is just how many theories the scientific community has producedand how wildly different some of them are. As you know when you throw a ball, the ball will stop when it runs out of energy and fall down. It is possible that the dark energy equation of state could change again, resulting in an event that would have consequences which are extremely difficult to predict or parameterize. Every now and then there would be a flash of light, almost like lightning, whenever an object was pulled close enough to a black hole to emit energy, and then it would fall dark again. This makes the calculations work out, but the boundaries that they draw invariably cut off sections of universes at the outer edges of the sample, the same way that you might cut off parts of Texas if you drew a circle on a map of the USA. < There are no black dwarf stars out there in the Universe because they takes billions even trillions of years to form and that the Universe is too young for them to appear. (Utopia) What if the reason for this is The Doctor himself? Why 28 + 47 = 72, Not 75, For Black Holes. 2 7 theories about the end of the Universe. The "Bible" Theory, This is the Creation theory and has . If you use enough energy, the string will break. There are four competing theories of how the universe will end, no one knows. Andrei and co say the minimum time before the acceleration ends is "strikingly soon, cosmologically speaking". At the time of the Big Bang, a point of almost infinite density exploded, creating galaxies that are still further apart. In the absence of dark energy, a flat universe expands forever but at a continually decelerating rate, with expansion asymptotically approaching zero. As a result, the Big Bang theory quickly became the most widely held view of the origin of the universe. The Simpsons withstanding, everything, eventually, will come to an end. However, after Hubble announced his conclusion that the universe was expanding, Einstein would write that his cosmological constant was "the greatest blunder of my life."[5]. Measurements from the Wilkinson Microwave Anisotropy Probe have confirmed the universe is flat within a 0.4% margin of error.[2]. There are those who believe in the Steady State Universe who believe the Universe is inifinite in time, it has no birth, has no end. But youd never know. Choosing among these rival scenarios is done by 'weighing' the universe, for example, measuring the relative contributions of matter, radiation, dark matter, and dark energy to the critical density. Observations of the stars and galaxies indicate that the universe is expanding. And as our universe expands, energy will continue to spread to all points in space. Forever. And then wed be left with the same conditions that the universe had before the Big Bangall the matter of the universe condensed into an infinitesimal point. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. 1 This is, however, unlikely to happen based on current knowledge, since weve recently discovered that the universe appears to be expanding at an accelerating rate. A somewhat similar idea is embraced by the cyclic model, but this idea evades heat death because of an expansion of the branes that dilutes entropy accumulated in the previous cycle. But still, this wouldnt be the final state of the universe. By saving humanity and ensuring that they survive and prevail no matter what, he makes them so "indomitable". By far the most accepted explanation is The Big Rip Theory. It is possible that, depending on the nature of Dark Energy, the .

There can only be one end fate for the universe but which one that will occur is anyone's guess. But this whole thing depends on dark energy. Among the theories that have been given so far about the destruction of the universe, the notable ones are-The Big Rip The Big Crunch The Big Freeze The Big Bounce Multiverse Theory. If you're looking for just the end of Earth, you should look at End of Life on Earth. In the email will be a link to unsubscribe to further notifications. Heat Death takes place when the universe has reached a state of maximum entropy all the available energy has moved to places with less energy and heat stops flowing. In general, dark energy is a catch-all term for any hypothesized field with negative pressure, usually with a density that changes as the universe expands. For the physical location, see, Last edited on 12 November 2022, at 16:16, Learn how and when to remove this template message, "Expansion of the universe, A homogeneous universe of constant mass and increasing radius accounting for the radial velocity of extra-galactic nebul", Monthly Notices of the Royal Astronomical Society, "Supernovae, an accelerating universe and the cosmological constant", "Dark Energy, Dark Matter - Science Mission Directorate", "Quantum cosmology and the creation of the universe". Enter Albert Einstein's Theory of Relativity and Edward Hubble's research into . Many have explained it in many ways. Each possibility described so far is based on a very simple form for the dark energy equation of state. The same paradox happens if you have eternal life. More concretely, competing scenarios are evaluated against data on galaxy clustering and distant supernovas, and on the anisotropies in the cosmic microwave background. The molecules and atoms that make up the universe will also disintegrate. The largest era of the Universe will contain black dwarves and black holes and they will be known as the Degenerate and Black Hole Eras. The flat Earth, the geocentric model, heliocentricity, galacticocentricity, the Big Bang, the Inflationary Big Bang. Think of heat death as the total opposite of the Big Crunch. "If the cosmological constant is the dominant thing in the universe," explains Mark Trodden, a co-director for the Penn Center for Particle Cosmology at the University of Pennsylvania, then instead of speeding up unsustainably and tearing itself apart . BOSTON If the "Higgs-like particle" discovered last year is . The idea was recently visited by a team of scientists that said if a mini black hole was inside one of these bubbles of true vacuum, the gravity of the black hole would shift the balance, causing the bubble to expand and consume the whole universe within just a fraction of a second. An artist's conception visualizes the beginning of the universe in the big bang or could it be the end of the universe? The Big Rip . Copyright 2022 IBTimes UK. Some scientists theorize that billions of years from now, the universe will tip over the brink. Factors that need to be considered in determining the universe's origin and ultimate fate include the average motions of galaxies, the shape and structure of the universe, and the amount of dark matter and dark energy that the universe contains. This selects one of three possible geometries depending on whether In this scenario, stars are expected to form normally for 1012 to 1014 (1100 trillion) years, but eventually the supply of gas needed for star formation will be exhausted. Several possible futures have been predicted by different scientific hypotheses, including that the universe might have existed for a finite and infinite duration, or towards explaining the manner and circumstances of its beginning. [17], This scenario allows the Big Bang to occur immediately after the Big Crunch of a preceding universe. According to The Big Rip Theory, there will come a time when the gravitational force will decrease and the effect of dark energy will increase so that the planets inside the galaxy will no longer be bound by their gravitational force. This has caused cosmologists to abandon the oscillating universe model. 1 The Eternal Universe. There is nothing called the end of the Universe. He has been a guest speaker on numerous national radio and television stations and is a five time published author. "In fact, they can be compared to geologic timescales," they say. Anyway, the Big Rip is one of the scariest prospects, because unlike other theories that occur after all the stars have died out in the Universe, this will happen in 16million years, when life will supposedly still exist on different planets. Subsequent cosmological theorizing has been designed so as to allow for this possible acceleration, nearly always by invoking dark energy, which in its simplest form is just a positive cosmological constant. [7] However, other recent measurements by Wilkinson Microwave Anisotropy Probe suggest that the universe is either flat or very close to flat.[2]. [24] Also, if the universe is closed, this theory would predict that once this universe collapses it will spawn another universe in an event similar to the Big Bang after a universal singularity is reached or a repulsive quantum force causes re-expansion. But when it does die, just how will the universe go? And because theres still matter out there, wed still have a universe and existence. By far the most accepted explanation is The Big . 2. 1.7.1 The Pros and Cons of the Bible-Based Theory. Image . No interaction will occur. It has also been referred to as the Big Chill or the Heat Death by some. Physics doesnt like this explanation, so some scientists have claimed that perhaps the universe doesnt go the whole way back to a singularity.
