“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. Next came “the graceful exit”, when inflation stopped. 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. 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. The pattern for this is Jesus Himself. Many competing Big Bang alternative stem from deep dissatisfaction with the idea of cosmological inflation. I have a hard time believing that the universe is infinite. “At large scales, it is not chaotic. Well, the story starts out with an Austrian mathematician and physicist called Christian Doppler. 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. The universe is finite. Express. I asked this last night but didn't get much of a response. • 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. Can infinities be nested—infinities of infinities? Both possibilities have mind-bending implications. How can the universe be infinite if it started expanding 13.8 billion years ago? “It’s a rather prosaic, conservative idea described at all times by classical equations,” Steinhardt says. Or, the Big Bang might be a transition point in a universe that has always been – and always will be – expanding. And that is probably the model of the Universe that we feel closest to now. But what if the Big Bang wasn’t actually the start of it all? Every time something happens, there is a new branch created. 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. Are there an infinite number of independent universes? The Bible teaches the life we live after we die will be real—just as real as this life, if not more so. 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. This is the currently selected item. Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. Perhaps the Big Bang was more of a “Big Bounce”, a turning point in an ongoing cycle of contraction and expansion. Aristotle argued that there is no such thing as an actual infinity. “Life is an emergent property of complex systems and goes away if the opposite process to emergence takes place (collapse of complexity). 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. To understand why exactly I believe this way lets take a look at the small, rather than the large. order back issues and use the historic Daily Express This means that, at present, we know that the universe i… Close. If the end of the universe is the big freeze then it could prove that yes the universe us infinite. (There might even be a “mirror you” pondering what life looks like on this side.). And it is these that make up dark matter, according to those who support the Mirror Universe theory. But in CCC, it never goes through a period of contraction – it only ever expands.Â, “The view I have is that the Big Bang was not the beginning,” says Penrose.  “That’s the number of years or more for the really big ones to finally evaporate away. that’s why most have no hair! So what are your thoughts? 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). “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. However, the Cosmos is infinite, see: answer to Does anyone really believe that the cosmos was caused by a "big bang"? Two possiblities exist: either the Universe/ space is finite and has a size, or it's infinite and goes on forever. 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. This could mean there are an infinite number of branches and multiverses stemming from the Big Bang – possibly even before. Archived. See today's front and back pages, download the newspaper, And, indeed, that it may even have an end. 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. The CMB is a major source of information about what the early Universe looked like. … Posted by. 4 years ago. So there would be an infinite number of galaxies and planets in an infinite universe. 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. "and the observable universe in finite," It is finite until The End, then it is entirely gone. Is the universe infinite or do we say that because we have not traveled to or seen its walls yet? A universe smaller than the observable. So what are your thoughts? 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. Perhaps the most challenging alternative to the Big Bang and inflation is Roger Penrose’s “Conformal Cyclic Cosmology” theory (CCC). Inflation offers a way to solve this so-called “homogeneity problem”. The universe we live in may not be the only one out there. newspaper archive. Shredded and extruded back into our container Universe. 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. 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. Lets say the numbers 1-19-23-45-46-53 are the numbers that popped out of the lotto machine. Like the Big Bounce, it involves a universe that might have existed forever. 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. When things finally cooled enough for the first hydrogen atoms to form, the Universe swiftly became transparent. Second, we live in a universe. The universe is enormous and seems flat to scientists again. 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. 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. The opaque superheated plasma that existed in the early moments will likely forever obscure our view. 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. 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”. If the universe is infinite in extent, then an actual infinity, or an infinite actuality, exists. 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. Without some mechanism to even out the temperature across the observable Universe, scientists would expect to see much larger variations in different regions. what do you think But it seems to fit the data pretty well, and is what most people would say is most likely.”. Conformal Cyclic Cosmology predicts that much of the Universe will be pulled into enormous black holes that will then boil away (Credit: NASA/JPL-Caltech). Our observableuniverse expanded from one tiny homogenous region within that primordial hot mess, producing the uniform CMB. “Do we really need to imagine that there exist an infinite number of messy universes that we have never seen and never will see in order to explain the one simple and remarkably smooth Universe we actually observe?” he asks. That’s possible but not likely. 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. If there is a boundary to the universe it must be finite. “I take one thing away from the observations of the last 30 years, which is that the Universe is unbelievably simple,” he says. The Mirror Universe offers all that – and might also solve one of the Universe’s big mysteries. IF the universe is infinite Thread starter Oldfart; Start date Sep 23, 2010 Sep 23, 2010 It is also a tantalising mystery for physicists. But there have always been shortcomings with the theory. 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. 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. Do the numbers of galaxies, and even of universes, have no end? 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. 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? We have to look for a better idea.”, Rather than being a beginning, the Big Bang could have been a moment of transition from one period of space and time to another – more of a bounce (Credit: Alamy). Both possibilities have mind-bending implications. In the example in the article, in 22 billion years the Universe will be completely … 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.”. In some variations, an infinite number of universe histories occur simultaneously at great distances from one another. When hyper-massive black holes collide, the impact creates a huge release of energy in the form of gravitational waves. 1.

The photo that summed up our place in the Universe, Is there a hidden code that rules the Universe. What would an Infinite Universe Mean? We won't be in a state of dreamlike consciousness, but we will fully exist in body, mind and soul. Sometimes it's too weak, and the universe implodes again before anything can form. 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 … Home of the Daily and Sunday Express. The Mathematical definition of ‘Infinity and beyond’ has all the Maths Experts scratching their heads …. Two possiblities exist: either the Universe is finite and has a size, or it’s infinite and goes on forever. 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. It’s not a particularly dramatic ending, although it does have a satisfying finality. If the universe is infinite, that would mean there is an infinite number of 'me' out there. Notably, there is no definitive mechanism to trigger inflationary expansion, or a testable explanation for how the graceful ending could happen. 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. The expanding Universe theory says that the Universe could expand forever [that corresponds to a 'flat' Universe]. “In that case, it is plausible that there is one in our future. 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.
