The theory argues that the inflationary phase of the Universe goes on forever; it didn't end for the Universe as a whole. A name is preferred even if its a random made up one by yourself. 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. 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. Matter will still be there, but in particle form, and its motion will be totally random. I am not suggesting you try the elastic band experiment because you will if you do it wrong will HURT yourself. 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. None of these theoretic endings for the universe are certain. Much like an electromagnetic field, it varies in strength based upon its potential. That's 3 or 4 . 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. Physics doesnt like this explanation, so some scientists have claimed that perhaps the universe doesnt go the whole way back to a singularity. The theory states that continued expansion of the universe will cause the fabrics of the universe to tear apart. 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. 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 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 . 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. The theory is known as the Steady State Theory which says matter lost is replaced by new matter. 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. Eventually, wed be left with nothing but gravity wells in an abyss. They could start in Big Bangs. Forever. The truly fascinating thing is just how many theories the scientific community has producedand how wildly different some of them are. 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. Finally, the entire universe will go dark. If you fix one end of a piece of string to a stationary object and pull the other end. 2.3 Number Three: Massive Black Holes. This theory, which recently hit headlines across the globe, says that a type of phantom dark energy will get stronger over time. What is dark energy that is not well understood? And as our universe expands, energy will continue to spread to all points in space. Current evidence also indicates the universe is not closed[citation needed]. General relativity can be employed to describe the universe on the largest possible scale. With a positive cosmological constant, it could also occur in a closed universe. Such a description seems to be at odds with other more widely accepted theories, especially quantum mechanics and its uncertainty principle. However, if the vacuum is not in its lowest energy state (a false vacuum), it could tunnel into a lower-energy state. [14] However, observations are not conclusive, and alternative models are still possible. This unknown energy is called dark energy. In this theory, the force of that rapid compression is enough to start off another big bang, and the universe starts again. Which has been going on since the Big Frog. 2.1 Number One: Big Crunch Theory. There is no synchronicity between the two eras. 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. 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. 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. Many have explained it in many ways. Why 28 + 47 = 72, Not 75, For Black Holes. This leads to a multiverse scenario, wherein space is broken into bubbles. Surprisingly, the possibilities they describe are very different. As the gravitational force weakens with expansion, the magnitude of this force becomes stronger. 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 . 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. It also highlights some lesser known theorists including Georges Lematre, who first theorised that there was a big bang, Ralph . Love podcasts or audiobooks? 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. Eventually, it will stop expanding and . "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 . 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. The Big Crunch, as you might have guessed, is the Big Bangs opposite. Freeze is more appropriate as the universe will get really really cold and not just a lower temperature. Many current theories suggest dark energy is a cosmological constant, a kind of uniform energy that exists throughout space. 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. is equal to, less than, or greater than Plasma-filled cosmos. 2.2 Number Two: Heat Death. Eventually, it will stop expanding and start collapsing into itself. 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. First, the Universe might have what we call positive curvature like a sphere. However, as the name is meant to imply, very little is currently known about the physics of dark energy. 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. Eventually these too will evaporate as the universe gets ever colder, leaving nothing behind. , the geometry of space is open, i.e., negatively curved like the surface of a saddle. This one feature makes it almost impossible to know where space ends. 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 Bounce is similar to the Big Crunch but far more optimistic. 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. Measurements from the Wilkinson Microwave Anisotropy Probe have confirmed the universe is flat within a 0.4% margin of error.[2]. Otherwise, thered be no way to discern one moment from the next. This has caused cosmologists to abandon the oscillating universe model. {\displaystyle \Omega >1} 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. At the time he published it in 1916, Einstein's theory of general relativity contained an odd term called the cosmological constant. Theories about the end of the universe. There is nothing to say that this has not happened before as its a theory and hard to disprove. Hence cosmologists aimed to determine the fate of the universe by measuring It is believed by many that the universe began around 13.7 billion years ago. This is based on the Big Bang theory, which is the most widely accepted theory of the universe's origins. The fate of the universe is determined by its density. Gravity slows the expansion of the universe and contracts everything back to the center. The Big Bounce. [17], This scenario allows the Big Bang to occur immediately after the Big Crunch of a preceding universe. It says the expansion of the universe (from the Big Bang) will not continue forever. Ah, the age-old notion that the universe always has beenand always will be. In the absence of dark energy, a flat universe expands forever but at a continually decelerating rate, with expansion asymptotically approaching zero. Are We Seeing a New Space Race That is Now Done Between Billionaires? With dark energy, the expansion not only continues but accelerates. 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. In one scenario they say the minimum time remaining before the end of expansion is roughly equal to the period since life has existed on Earth. If understood, we could be more sure, of what is going to happen. Then surely some unknown force is working against the force of gravity. And we will take that moment as the death of this universe. This is also a paradox - humanity are special because The Doctor saves them, but he saves . You guessed it - it is expansion. "End of the universe" redirects here. One of these ideas (theories) was (at the time) a finite universe that expanded and reached a maximum size and then contracted. [4] In 1948, Fred Hoyle set out his opposing Steady State theory in which the universe continually expanded but remained statistically unchanged as new matter is constantly created. One unlikely scenarios is that we live life back in reverse, instead of life to death, it'll be death to life. Our current understanding is that time and space began during the Big Bang , when a subatomic, ultra-hot and super-dense point . 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 heat death scenario is compatible with any of the three spatial models, but requires that the universe reaches an eventual temperature minimum.[23]. 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. If we extrapolate that to our universe, we wind up with all of the matter evenly dispersed throughoutin a cold, dark, boring mist. . The flat Earth, the geocentric model, heliocentricity, galacticocentricity, the Big Bang, the Inflationary Big Bang. And because theres still matter out there, wed still have a universe and existence. [4] In some of these solutions, the universe has been expanding from an initial singularity which was, essentially, the Big Bang. 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. However, they also said if this was going to happen, it would have already. 9. There can only be one end fate for the universe but which one that will occur is anyone's guess. [18] Over infinite time, there would be a spontaneous entropy decrease by the Poincar recurrence theorem, thermal fluctuations,[19][20] and the fluctuation theorem. [25] This is called vacuum decay. Jenna (Jennifer) and Matt (Mark) get married at the end of 13 going on 30 right? 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. As the energy density, scale factor and expansion rate become infinite the universe ends as what is effectively a singularity. Then something caused it to explode. Ah, the age-old notion that the universe always has beenand always will be. Alexander Friedmann proposed several solutions in 1922, as did Georges Lematre in 1927. Copyright 2022 IBTimes UK. 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. 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. A black, empty, dark and cold space is what remains according to the theory of heat death. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. Well be left with just particles in a void. No interaction will occur. Before discussing the universe's end, let's go into its birth. There's no register feature and no need to give an email address if you don't need to. The most prominent theory for how the universe began is the Big Bang, where all matter first existed as a singularity, an infinitely dense point in the abyss of nothing. 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. According to a popular theory, most matter in the universe is orbiting black holes. As for whether you'd do the same thing again, I couldn't possibly say. There are those who believe that there will be no end to the Universe, that the Universe will continue for every. By doing this, the energy density will gradually decrease. In this case, gravity is not strong enough to overcome the expansion, so the universe just keeps on expanding exponentially. What if there were no more moments? 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. By far the most accepted explanation is The Big . [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. 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. 1.) The molecules and atoms that make up the universe will also disintegrate. [17] It could, in the absence of dark energy, occur only under a flat or hyperbolic geometry. As a result, the planets will move away from each other. 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. [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. As we know, our universe is gradually expanding. 2. Multiverse and Parallel Universe / Worlds Theory. [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. If you use enough energy, the string will break. Just the same instant in time. > < , 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. It says the expansion of the universe (from the Big Bang) will not continue forever. In cosmic terms, this is short compared to what lies ahead for the Universe. 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. An important parameter in fate of the universe theory is the density parameter, omega ( It's like a universe inside a universe. 2.6 Number Six: The Big Rip. According to one version of the Big Bang theory of cosmology, in the beginning the universe was infinitely dense. 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). {\displaystyle \Omega =1} Newton 2.0.

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. {\displaystyle \Omega } Youd never die. When the Universe started, there was an enormous amount of energy that pushed matter from the centre. 1 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. Slowly, stars will fizzle out, turning night skies black. The universe will be in a state of equilibrium, and these particles will bounce off of one another without exchanging energy. 1 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. As you know when you throw a ball, the ball will stop when it runs out of energy and fall down. It maintains that the Universe will expand forever, getting colder and colder. So, let's assume (I hate that word) there isn't. 3. Each model explains what was known at the time and what the measurements could confirm. But the universe wouldnt be anything that we could comprehend. However, there are a number of problems with this theory, one of which being that the universe is expanding at an ever increasing rate. Sign up and stay up to date with our daily newsletter. We don't know if there is anything to stop it. The Simpsons withstanding, everything, eventually, will come to an end. Study author Simon Driver said: "The universe will decline from here on in, sliding gently into old age. The matter expanded outward at an incredible rate and eventually formed the universe we see today. 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. But when it does die, just how will the universe go? 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. 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. Here are the top theories about the ultimate fate of the universe. Cosmology 101: The End - Universe Today. When this happens, at some point in the universe, a bubble will appear. The Big Rip . 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). One theory describes the end of the universe as the Big Rip. 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. More concretely, competing scenarios are evaluated against data on galaxy clustering and distant supernovas, and on the anisotropies in the cosmic microwave background. 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. This is true for school, for work, for life, for Earth, and for the universe as well. But its sure to be a far more violent death than the slow heat death most people were expecting. There are two features of the Universe that are key to understanding its fate; they are its density and its shape. But this whole thing depends on dark energy. [7] However, other recent measurements by Wilkinson Microwave Anisotropy Probe suggest that the universe is either flat or very close to flat.[2]. The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. What are the 7 theories of the origin of the universe? , or equivalently the rate at which the expansion was decelerating. All . 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. Whether there is a universe or not, time has to chug on. This equilibrium also happens with all other forms of energy. 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 . Learn on the go with our new app. As we make developmental leaps in science and technology, and are able to journey or peer further and further out into the cosmos, both . Eventually, the stars will all wink out, one by one, and there wont be enough energy left to ignite new ones. 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. 2. The universe is expanding and once it gets to a certain size, the energy will have run out and dissipate. No matter how the world ends, scientists feel the need to use the (horribly understated) word big to describe it. Andrei and co say the minimum time before the acceleration ends is "strikingly soon, cosmologically speaking". 7. 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. (Utopia) What if the reason for this is The Doctor himself? 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. When this happens, it will pull everything in the universe inside it turning into the biggest ever black hole. [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]. 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. The universe has basically sat down on the sofa, pulled up a blanket and is about to nod off for an eternal doze.". By saving humanity and ensuring that they survive and prevail no matter what, he makes them so "indomitable". But the surprising thing is that they do not slow down. 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.) {\displaystyle \Omega } This theory is about the Universe expanding so much that it rips itself apart. 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. According to this theory, gravity will eventually cause this expansion to slow to the point where it halts and begins to contract instead. Recent calculations say this will happen in about 22 billion years. Eventually the time that stars existed will be no more than a blink in the eye. The Big Crunch hypothesis is a symmetric view of the ultimate fate of the universe. Rather, it is increasing gradually. ), defined as the average matter density of the universe divided by a critical value of that density. {\displaystyle 1} At the time of the Big Bang, a point of almost infinite density exploded, creating galaxies that are still further apart. Einstein and his contemporaries believed in a static universe. Each possibility described so far is based on a very simple form for the dark energy equation of state. 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 . = The expansion speed of cosmic objects like galaxies, clusters, etc. This theory is about the Universe expanding so much that it rips itself apart. Many theories have been given so far on how our universe will be destroyed. In this theory, an unseen force called dark energy is causing the accelerating expansion of the universe that weve observed. Galaxies drift apart like forlorn lovers, and the all-encompassing night between them becomes wider and wider. They had to change their names somewhere in between for unknown reasons but I believe these two movies take . 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]. The "Bible" Theory, This is the Creation theory and has .

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. 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. is supposed to slow down after some time under the influence of gravitational force. Many theories have been given so far on how our universe will be destroyed. This article is copyrighted by IBTimes.co.uk, the business newsleader, IBT UK Morning Brief - Let the best of International News come to you. "In fact, they can be compared to geologic timescales," they say. 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. As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. Because no more work can be extracted, the universe is effectively dead. 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. As a result, the tendency of all objects in the universe to move away increases. This bubble will expand in all directions at the speed of light and wipe out everything it touches. The Big Bounce is a theorized scientific model related to the beginning of the known universe. That is, as they are moving away from each other, the speed of their moving away is increasing. [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. Youd never grow old. (1) Edwin Hubble discovered that the universe was . 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. Big Crunch. How are galaxies moving away faster than light? They make it to the furthest reaches of the universe, surviving until the end. Imagine the same scenario: Gravity slows the expansion of the universe and condenses everything back into one single point. In this scenario in 22 billion years, all things will be torn apart, including planets, atoms, and even time. It will always be here. 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. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. 1. When I say long, I really mean long, there is not enough bandwidth to say how long it might be. Some scientists theorize that billions of years from now, the universe will tip over the brink. The laws of physics will be different, and there might even be life. 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. 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. 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. If you fix one end of a piece of string to a stationary object and pull the other end. 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]. 2.5 Number Five: The Big Bounce. It says that due to the continuous expansion, all the elements that make up the universe, from atoms to galaxies, will be broken. According to the physics, the number of new universes will always outnumber the old ones, so in theory, the number of universes is increasing. A large part of black hole theory involves the cannibalization of stars or even entire galaxies as they fall into the holes event horizon. . > Nevertheless, new possibilities are arriving with surprising rapidity. 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 . Gravity poses a problem. [16] This scenario, in combination with the Big Rip scenario, is gaining ground as the most important hypothesis. [8], If This is the default option given the best data we have today. Dark energy is an expansion-dominating cosmological constant. The universe follows the same rules as any thermodynamic system, and they all end up the same way: with heat evenly distributed throughout. Lets discuss this briefly. The sum of the angles of a triangle exceeds 180 degrees and there are no parallel lines; all lines eventually meet. They claim the universe did not end. 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. Image . The same paradox happens if you have eternal life. 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. It actually might not end, its just so far ahead in the future we don't know. 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. 1 The Big Bounce is somewhat like the Big Crunch but this one is somewhat of a positive theory. A universe is anything and everything in existence. The Big Crunch is the opposite of the Big Bang, which explains the origin of the universe. There are four competing theories of how the universe will end, no one knows. The force of that compression can very well cause another big bang/ explosion, and another new universe kicks off. If you give an email address, you may receive an email notifying you when someone else has added a comment to the same page. Think of it as an alternate universe (though its really the same universe with different properties). 2.4 Number Four: The End of Time. All existing stars will eventually burn out leaving only black holes behind. 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. {\displaystyle \Omega <1} 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. 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. If you're looking for just the end of Earth, you should look at End of Life on Earth. {\displaystyle \Omega >1} The theory states that continued expansion of the universe will cause the fabrics of the universe to tear apart. and in the Adam Project they're married have a son but he's dead. But still, this wouldnt be the final state of the universe. 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. And at that moment no power can be used. Even without dark energy, a negatively curved universe expands forever, with gravity negligibly slowing the rate of expansion. The geometry of the universe is, at least on a very large scale, elliptic. We could be locked in an endless birth, death, rebirth recycle. There are three possibilities of the shape of the Universe. 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. And this universe-wide cataclysm could burn them alive, tear them apart, or feed them to the space lions that live between universes. 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]. Enter Albert Einstein's Theory of Relativity and Edward Hubble's research into . Observations of the stars and galaxies indicate that the universe is expanding. All the material in the universe will explode. 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. 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. 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). All messages will be reviewed before being displayed. It has also been referred to as the Big Chill or the Heat Death by some. Corbis. This theory requires the Universe to be either flat or negatively curved. 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). You live an infinite time, so anything that is possible is guaranteed to happen (and happen an infinite number of times). {\displaystyle \Omega } If the average density of the universe exactly equals the critical density so that The Big Bounce is a bit more optimistic in that it says the universe will never really end. 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 . As long as . 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. The geometry of such a universe is hyperbolic.[9]. 1 The Eternal Universe. It would just be that one instant in time. The Universe is only 13.5 Billion Years old, it still has the vast part of his life ahead of us. A true vacuum exists so long as the universe exists in its lowest energy state, in which case the false vacuum theory is irrelevant. In a closed universe, gravity eventually stops the expansion of the universe, after which it starts to contract until all matter in the universe collapses to a point, a final singularity termed the "Big Crunch", the opposite of the Big Bang. Even then, he says the universe will have free particles still existing. With an infinite amount of time, anything that could possibly happen has a 100 percent probability of happening. 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. One of the most fascinating things about the universe is how little we really know. By far the most accepted explanation is The Big Rip Theory. The Big Bang theory states that the universe began as a very small, incredibly dense and hot ball of matter. If this happens repeatedly, it creates a cyclic model, which is also known as an oscillatory universe. General Relativity: The World Ends in Ice. 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 it doesnt matter: In a multiverse, our universe is just one of many. Okay so 13 going on 30 and the Adam Project both star Jennifer Garner and Mark Ruffalo! In simple terms, this theory states that the universe will continuously repeat the cycle of a Big Bang, followed up with a Big Crunch. 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. It is also possible that all structures will be destroyed instantaneously, without any forewarning. . Many have explained it in many ways. 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). Assume we live in a universe that never ends. To get around this problem, scientists take a section of the universe and just calculate probabilities for it. You can decline to give a name which if that is the case, the comment will be attributed to a random star. Just look at galaxies, which contain almost everything and house supermassive black holes in their centers. Up until the beginning of the 20th century, the universe was believed to be infinite and ageless. Even though time itself could run out in other universes, in a multiverse, new universes are being born all the time. In a multiverse scenario, with infinite universes, these universes may spring in or out of existence. In order to best understand the false vacuum collapse theory, one must first understand the Higgs field which permeates the universe. 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. From then on, the beginning of the universe and its possible end have been the subjects of serious scientific investigation. 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. But what if time lost momentum and just froze? Its anyones guess. The theory does, however, require that the acceleration of the expansion either remains constant or slows down. In a closed Universe, you could, in . At some point, it will be close to zero. Assuming you were still alive to experience this (in billions of years, long after the Earth is gone), youd never realize anything was amiss. 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 . 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. Eventually, this bubble will destroy everything in the 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.
