Last I read, it appeared that it was impossible to create a completely convincing simulation of the Universe. The Earth seemed flat because it looked so big. While particle physicists have yet to directly see any of these particles, they are pretty sure they exist. Is our universe infinite in size and contents? There being an infinite amount of time does not mean that you will exist again, in the same way that just because the real line is infinite does not mean that the number 1 occurs more than once. But, big as that is, it still isn't infinite. u/doorkn00b. The pattern for this is Jesus Himself. It is unlikely that we will ever be able to directly observe what happened in the first moments after the Big Bang, let alone the moments before. Is the universe infinite or finite? Do the numbers of galaxies, and even of universes, have no end? Now, one expert believes this could be the key to life after death. Eventually these lumps of matter will drift so far apart that they will slowly disappear, according to some models. He wrote on Q+A site Quora: “Life after death exists as a global phenomenon, but my life ends when the entropy of the system … Therefore, I am immortal and I shall never die in one sense, as there will always be another 'me' born again, and so the cycle repeats itself an infinite number of times. Astronomer Royal Martin Rees has previously said the next major breakthrough will be realising there are many universes, and ours is just one particular patch in space and time. There are a number of proposals for various ways of applying measure theory to an infinite expanding universe, but there's no way to select which one is the right one. But I always say that we don't know for sure that this happened. Maybe it won't happen until a near infinite amount of time has passed, but if the Universe is truly infinite, won't everything that is possible to happen happen an infinite amount of times? I have a theory on life and death: if the universe is infinite and never ending, then the same thing has to happen over again, eventually. The Cosmic Microwave Background (or “CMB”) has been a fundamental factor in every model of the Universe since it was first observed in 1965. It's incredibly ordered and regular and requires very few numbers to describe everything.”, Our forward-time flowing universe could have a perfect reflection that also extends out in reverse from the event we call the Big Bang (Credit: Alamy). The Big Rip is considered possible. But there have always been shortcomings with the theory. This mysterious stuff accounts for about 85% of the matter in the universe. Please see our Privacy Notice for details of your data protection rights. For example, take lotto numbers. Having the same quantum processes is the main constraint behind cloning a person’s mind, as there is no way to induce the same reactions. Morning Edition is asking questions about the universe, part of an effort to put things in perspective. Is The Universe Infinite . Our expanding universe could start to contract, returning to that dense state and starting the bounce cycle again.”. Penrose calls the patterns left behind by evaporating black holes “Hawking Points”. The expanding Universe theory says that the Universe could expand forever [that corresponds to a 'flat' Universe]. And then you’ve got a universe really dominated by photons (particles of light).”. Two possiblities exist: either the Universe is finite and has a size, or it’s infinite and goes on forever. Lets say the numbers 1-19-23-45-46-53 are the numbers that popped out of the lotto machine. With a bounce rather than a bang, Steinhardt says, distant parts of the cosmos would have plenty of time to interact with each other, and to form a single smooth universe in which the sources of CMB radiation would have had a chance to even out. In fact, it’s possible that time has existed forever. Both possibilities have mind-bending implications. In the Medieval dark age people thought the world was flat. It’s a faint, ambient radiation found everywhere in the observable Universe that dates back to that moment when the Universe first became transparent to radiation. We hear from scientists who ponder what shape the universe has and whether it is truly infinite. In astrophysics and physical cosmology, Olbers' paradox, named after the German astronomer Heinrich Wilhelm Olbers (1758–1840), also known as the "dark night sky paradox", is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe.In the hypothetical case that the universe … But more recently, another of Steinhardt’s collaborators, Anna Ijjas, developed a model in which the Universe never gets so small that quantum physics dominates. Neil Turok has also been exploring another avenue for a simpler alternative to inflationary theory, the “Mirror Universe”. What would an Infinite Universe Mean? Because there are a finite number of possible universe histories, there are an infinite number of occurrence of each one. "and the observable universe in finite," It is finite until The End, then it is entirely gone. To mark the end of a turbulent year, we are bringing back some of our favourite stories for BBC Future’s “Best of 2020” collection. Discover more of our picks here. I'm not saying it is; I'm under the impression we don't know for sure whether it is or not. However, in an infinite and eternal universe, it could be possible that an exact remake of your consciousness is created, which would allow you to live again, according to Mr Jacholkowski. And it is these that make up dark matter, according to those who support the Mirror Universe theory. If however there is an infinitesimal probability of something happening, then in an infinite universe there would only be a finite number (for example 1) of those things. I asked this last night but didn't get much of a response. The physics world has, however, remained largely skeptical of these results to date and there has been limited interest among cosmologists about even attempting to replicate Penrose’s analysis. Since there "infinite" possible Earths, there are infinite possibilities for humans there, wouldn't that mean, that ultimately, there IS an Earth(if Universe is infinite) that basically EVERYTHING is the same as our Earth? What we know with certainty is that the Big Bang occurred 13.8 billion years ago, meaning that is the age of the universe. Aristotle argued that there is no such thing as an actual infinity. Multiverse bombshell: There could be infinite versions of YOU, Time travel breakthrough: Experts solve paradoxes of time travel, Life after death is REAL if infinite universes exist, physicist claims, Infinite universe could provide life after death, ‘No white lights or angels’: THIS is what happens when you die, Life after death: Man believes he visited the AFTERLIFE, "Sooner or later a copy of myself will be realised somewhere else.”, “There may have been many big bangs, not just one. A infinite universe, with infinite matter implies infinite possibilities. Sort by: Top Voted. Inflation offers a way to solve this so-called “homogeneity problem”. If the end of the universe is the big freeze then it could prove that yes the universe us infinite. The usual story of the Universe has a beginning, middle, and an end. When Jesus died on the cross and was laid in a tomb, His physical body was completely … “Something had to connect those two regions of the Universe in the past. Therefore we live in a special time – the only time in history when we may be scientifically certain of both the beginning and the end of the universe. Both possibilities have mind-bending implications. Next came “the graceful exit”, when inflation stopped. In the 19th century, Doppler tried to explain an unusual phenomenon about electromagnetic waves: if and observer moves towards or … Just because the Universe is eternal doesn't mean that everything possible will happen. dose that mean that an infinite number of me is living every second of my life, happening at the same time somewhere in the infinite universe.. nobody know, i know that. Our observableuniverse expanded from one tiny homogenous region within that primordial hot mess, producing the uniform CMB. A universe smaller than the observable. “You have to think in terms of something like a googol years, which means a number one with 100 zeros,” says Penrose. But rather than being the beginning of space and time, that was a moment of transition from an earlier phase during which space was contracting. But it seems to fit the data pretty well, and is what most people would say is most likely.”. Our mission is to provide a free, world-class education to anyone, anywhere. “I take one thing away from the observations of the last 30 years, which is that the Universe is unbelievably simple,” he says. Do stars and spaces go on forever? “Just as Earth is a very special planet among zillions of others, so—on a far grander scale—our big bang could have been a rather special one.”. The theory says spacetime should be warped by primordial gravitational waves that ricocheted out across the Universe with the Big Bang. This Big Bounce model says this is how the Universe must be.”. Archived. However, the Cosmos is infinite, see: answer to Does anyone really believe that the cosmos was caused by a "big bang"? For the next 380,000 years, the Universe was so dense that not even light could move through it – the cosmos was an opaque, superhot plasma of scattered particles. Doesn't that mean there are infinite possibilities for there to be another Solar System, exactly like ours, with an Earth EXACTLY like ours, with people, JUST like us. ... Do you think you will eventually live again when atoms and particles form exact same universe … When hyper-massive black holes collide, the impact creates a huge release of energy in the form of gravitational waves. As the Universe expands and cools to near absolute zero, those black holes will “boil away” through a phenomenon called Hawking Radiation. Sometimes it's too weak, and the universe implodes again before anything can form. ", Life after death: THIS is the process you will go through when you die, Life after death: Scientist’s claims 'you’re going to this place’, Life after death: Chaplain reveals communication from beyond grave, Life after death: Shocking research reveals what happens when you die, NASA news: Space agency shows ‘galactic firework display’, Meteor BREAKTHROUGH: Oldest material ever discovered in meteor, Universe is ALIVE: Consciousness pervades through cosmos down to atoms. Can infinities be nested—infinities of infinities? This could mean there are an infinite number of branches and multiverses stemming from the Big Bang – possibly even before. So what are your thoughts? The universe carried on expanding and cooling, but at a fraction of the initial rate. These are 2 separate questions, and must be answered individually: 1. The Bible teaches the life we live after we die will be real—just as real as this life, if not more so. Express. Our universe is not the universe — there might be others. With this in mind, Turok sees no place for a multiverse, higher dimensions, or new particles to explain what can be seen when we look up at the heavens. All of these theories sit outside mainstream cosmology, but all are supported by influential scientists. Until then, the story of our universe, its beginnings and whether it has an end, will continue to be debated. READ MORE: Life after death: THIS is the process you will go through when you die. It’s not a particularly dramatic ending, although it does have a satisfying finality. We will use your email address only for sending you newsletters. “It’s the only particle on that list (of particles in the Standard Model) that has the two requisite properties that we haven't directly observed it yet, and it could be stable,” says Latham Boyle, another leading proponent of the Mirror Universe theory and a colleague of Turok at the Perimeter Institute. “The entire picture of what we know nowadays, the whole history of the Universe, is what I call one ‘aeon’ in a succession of aeons.”. I wholeheartedly believe that the universe that we live in is infinite. Penrose says at this point, the Universe begins to look much as it did at its start, setting the stage for the start of another aeon. “Each constituent of this ‘multiverse’ could have cooled down differently, maybe ending up governed by different laws. He wrote on Q+A site Quora: “Life after death exists as a global phenomenon, but my life ends when the entropy of the system of atoms forming my body is subject to a drastic rise. The remainder seems to be made up of something we cannot currently see – dark matter. The CMB is a major source of information about what the early Universe looked like. And, indeed, that it may even have an end. For the first 380,000 years of the current aeon, these would have been nothing more than tiny points in the cosmos, but as the Universe has expanded, they would appear as “splotches” across the sky. So what are your thoughts? The Mirror Universe offers all that – and might also solve one of the Universe’s big mysteries. The “Big Bounce” theory agrees with the Big Bang picture of a hot, dense universe 13.8 billion years ago that began to expand and cool. [1] An actual, or completed, infinity seems to be literally a contradiction in terms; it seems to entail an end of something without an … The photo that summed up our place in the Universe, Is there a hidden code that rules the Universe. Two possiblities exist: either the Universe/ space is finite and has a size, or it's infinite and goes on forever. • Did "dark stars" help form our universe• The photo that summed up our place in the Universe• Is there a hidden code that rules the Universe. Scars left by the Big Bang in a weak microwave radiation that permeates the entire cosmos provides clues about what the early Universe looked like (Credit: Nasa), “I have to confess, I never liked inflation from the beginning,” says Neil Turok, the former director of the Perimeter Institute for Theoretical Physics in Waterloo, Canada.Â. Theoretical physicists are increasingly finding that inflation theory fails to account for the spread of matter and energy observed in the Universe (Credit: Nasa/ESA), “Inflation seems to be the thing that has enough support from the data that we can take it as the default,” says Mack. Second, we live in a universe. Mass and energy would be so diluted that it will be very empty, close to absolute zero Kelvin temperature with the occasional lonely particle flying about. “It’s a rather prosaic, conservative idea described at all times by classical equations,” Steinhardt says. Join one million Future fans by liking us on Facebook, or follow us on Twitter or Instagram. I'm not saying it is; I'm under the impression we don't know for sure whether it is or not. That’s possible but not likely. Mainly because of 2 reasons. It predicts that another universe dominated by antimatter, but governed by the same physical laws as our own, is expanding outwards on the other side of the Big Bang – a kind of “anti-universe”, if you like. I think that it is relatively safe to say that no matter how good our microscopes get, we will never really find "the smallest thing in existence". “It can only say that the observable Universe might be like this or that or any other possibility you can imagine, depending on where we happen to be in the multiverse. Physicists have been examining the ‘many worlds’ or infinite universe theory for decades, and one expert believes it could be the key to life after death. LIFE after death could in some form be possible if the infinite universe theory is proved to be true, one physicist has claimed. If the end of the universe us the big rip then either if us could be right but I guess we won't live … In some variations, an infinite number of universe histories occur simultaneously at great distances from one another. what do you think If the universe is infinite in extent, then an actual infinity, or an infinite actuality, exists. But even with tweaks like this, inflation makes predictions that have, at least thus far, not been confirmed. In the example in the article, in 22 billion years the Universe will be completely … (There might even be a “mirror you” pondering what life looks like on this side.). This Universe ends in another 125 billion years, at our current acceleration of expansion. If the universe is infinite, that would mean there is an infinite number of 'me' out there. But it could also be finite, because it could be that the Universe has a very large volume now, but finite, and that that volume will increase, so only in the infinite future will it actually be infinite. Theoretically, this could mean there are an infinite number of versions of you based on infinite combinations of decisions taken during a lifetime. To understand why exactly I believe this way lets take a look at the small, rather than the large. “The inflationary paradigm has failed,” adds Paul Steinhardt, Albert Einstein professor in science at Princeton University, and proponent of a “Big Bounce” model. Are there different kinds of infinite universes? If you liked this story, sign up for the weekly bbc.com features newsletter, called “The Essential List”. He theorised there could have been more than one Big Bang which leads to many universes, and ours was simply lucky. I agree that it is likely that intelligent life will be around for many millions of years more, but eventually the universe will kill us all. Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. If the end of the universe if the big crunch then that would toss your argument if the universe being infinite into the toilet. 4 years ago. The Universe we can currently see is made up of clumps of particles, dust, stars, black holes, galaxies, radiation (Credit: NASA/JPL-Caltech/ESA/CXC/STScI). “And if a bounce happened in our past, why could there not have been many of them?” says Steinhardt. IF the universe is infinite Thread starter Oldfart; Start date Sep 23, 2010 Sep 23, 2010 It began with the Big Bang 13.8 billion years ago when the Universe was tiny, hot, and dense. Well, the story starts out with an Austrian mathematician and physicist called Christian Doppler. “The hope is not necessarily that we're going to see the beginning more directly, but that maybe through some roundabout way we'll better understand the structure of physics itself.”. Steinhardt and Turok worked together on some early versions of the Big Bounce model, in which the Universe shrunk to such a tiny size that quantum physics took over from classical physics, leaving the predictions uncertain. Physicist Adam Jacholkowski, former particle physicist at CERN from 1983-2015, believes that if the infinite universe theory is correct, then there is bound to be an exact carbon copy of your brain where the quantum processes are the same too. “Hopefully it will be possible in the future to clone our minds but it is rather a kind of science fiction as this cloning will be never perfect due to possible quantum processes in our minds, impossible to reproduce. “The theory is completely indecisive,” says Steinhardt. However, in an infinite and eternal universe, it could be possible that an exact remake of your consciousness is created, which would allow you to live again, according to Mr Jacholkowski. The universe is enormous and seems flat to scientists again. The problem here is that there's no uniform way to apply probabilities to an infinite, expanding universe. “In that case, it is plausible that there is one in our future. The Universe will become a cold, uniform soup of isolated photons. Perhaps the Big Bang was more of a “Big Bounce”, a turning point in an ongoing cycle of contraction and expansion. that’s why most have no hair! “Life is an emergent property of complex systems and goes away if the opposite process to emergence takes place (collapse of complexity). Home of the Daily and Sunday Express. Steinhardt, who was one of the original architects of inflationary theory, ultimately got fed up with the lack of predictiveness and untestability. But there are other potentially observable phenomena such as primordial gravitational waves, primordial black holes, right-handed neutrinos, that could provide us some clues about which of the theories about our universe are correct. – user2735 Nov 26 '12 at 22:09 If the universe is infinite, and there is a possibility different from zero for us to find ourselves not been contacted by our doppelgänger yet, then that scenario is happening just right now, with 100% of certainty. “There may have been many big bangs, not just one. Penrose has been working with Polish, Korean and Armenian cosmologists to see if these patterns can actually be found by comparing measurements of the CMB with thousands of random patterns. ”It's the one I teach in my classes. In fact, our universe could be just one of an infinite number of universes making up a "multiverse." We won't be in a state of dreamlike consciousness, but we will fully exist in body, mind and soul. I have a hard time believing that the universe is infinite. If you add up all the known mass in a galaxy – stars, nebulae, black holes and so on – the total doesn’t create enough gravity to explain the motion within and between galaxies. This means that, at present, we know that the universe i… 2. This is the currently selected item. “Inflation says there’s a multiverse, that there’s an infinite number of ways the Universe might come out, and we just happen to live in the one that is smooth and flat. So there would be an infinite number of galaxies and planets in an infinite universe. A handpicked selection of stories from BBC Future, Culture, Worklife, and Travel, delivered to your inbox every Friday. Close. But while certain types of gravitational waves have been detected, none of these primordial ones have yet been found to support the theory. Two possiblities exist: either the Universe is finite and has a size, or it’s infinite and goes on forever. Physicists have been examining the ‘many worlds’ or infinite universe theory for decades, and one expert believes it could be the key to life after death. See today's front and back pages, download the newspaper, order back issues and use the historic Daily Express The universe we live in may not be the only one out there. And that is probably the model of the Universe that we feel closest to now. "If time is infinite," Time is finite. Or, it could be more like a point of reflection, with a mirror image of our universe expanding out the “other side”, where antimatter replaces matter, and time itself flows backwards. If there is a boundary to the universe it must be finite. If recurrences occur an infinite number of times, some of those … In every direction scientists point a radio telescope, the CMB looks the same, even in regions that seemingly could never have interacted with one another at any point in the history of a 13.8 billion-year- old universe.Â, “The CMB temperature is the same on opposite sides of the sky and those parts of the sky would never have been in causal contact,” says Katie Mack, a cosmologist at North Carolina State University. It is also a tantalising mystery for physicists. Dr Rees writes in his new book, ‘On The Future: Prospects For Humanity’: “What we’ve traditionally called ‘the universe’ — the aftermath of ‘our’ big bang—maybe just one island, just one patch of space and time, in a perhaps infinite archipelago. Perhaps the most challenging alternative to the Big Bang and inflation is Roger Penrose’s “Conformal Cyclic Cosmology” theory (CCC). : Read about our approach to external linking. However, due to the inflation of the universe, as well as the apparently accelerating expansion of every observable corner of the universe, the most distant light we have been able to detect is from roughly 46 billion light-years in every direction. In less than a billionth of a billionth of a second, that pinpoint of a universe expanded to more than a billion, billion times its original size through a process called “cosmological inflation”. Both of these phenomena are so powerful, Penrose says, that they can “burst through to the other side” of a transition from one aeon to the next, each leaving its own kind of “signal” embedded in the CMB like an echo from the past. However, in an infinite and eternal universe, it could be possible that an exact remake of your consciousness is created, which would allow you to live again, according to Mr Jacholkowski. “I say no. Infinite means .. limitless or endless in space, extent, or size; impossible to measure or calculate, so I could say yes the universe is Infinite. Like the Big Bounce, it involves a universe that might have existed forever. Is the universe infinite or do we say that because we have not traveled to or seen its walls yet? Both possibilities have mind-bending implications. “The main reason that it didn't die at birth is that it was the only thing people could think of to explain what they call the ‘scale invariance of the Cosmic Microwave Background temperature fluctuations’.”. Shredded and extruded back into our container Universe. The Mathematical definition of ‘Infinity and beyond’ has all the Maths Experts scratching their heads …. … What is the meaning of infinity. The infinite universe theory dictates that every time a decision or action is taken, a new branch of a timeline is created where an alternate decision is made. Universe bombshell: There could be infinite versions of YOU, scientist claims THERE could be an infinite amount of universes and each person on Earth could exist in …  “That’s the number of years or more for the really big ones to finally evaporate away. Radiation burst out in every direction, and the Universe was on its way to becoming the lumpy entity we see today, with vast swaths of empty space punctuated by clumps of particles, dust, stars, black holes, galaxies, radiation, and other forms of matter and energy. For starters, the fact that we know the observable universe to be 93 billion light-years across is astonishing — that’s a great story in itself, and you can read about it extensively here — but how do we know it? The growing number of these competing theories suggests that it might now be time to let go of the idea that the Big Bang marked the beginning of space and time. Physicists have been examining the ‘many worlds’ or infinite universe theory for decades, and one expert believes it could be the key to life after death. The problem might have to do with the Big Bang itself, and with the idea that there was a beginning to space and time. Are there an infinite number of independent universes? Now only the Flat Earth people believe that the Earth is flat. The initial answer to whether the universe is infinite or finite is a resounding… we don’t know. Something had to tell that part of the sky to be the same temperature as that part of the sky.”. DON'T MISSLife after death: Scientist’s claims 'you’re going to this place’Life after death: Chaplain reveals communication from beyond graveLife after death: Shocking research reveals what happens when you die, “There is also another possibility that if the concept of an infinite multiverse is correct, sooner or later a copy of myself will be realised somewhere else.”. First, the observable universe is the one we have size estimates for, because I repeat, we don’t even know if the entire universe is infinite or finite, so size measurements don’t make any sense. “At large scales, it is not chaotic. Or, the Big Bang might be a transition point in a universe that has always been – and always will be – expanding. Every time something happens, there is a new branch created. “As we develop new theories and new models of cosmology, those will give us other interesting predictions that can that we can look for,” says Mack.
