That’s possible but not likely. The Bible teaches the life we live after we die will be real—just as real as this life, if not more so. 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. Do the numbers of galaxies, and even of universes, have no end? that’s why most have no hair! Are there different kinds of infinite universes? “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. Mainly because of 2 reasons. 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. Are there an infinite number of independent universes? But, big as that is, it still isn't infinite. 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). Second, we live in a universe. 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. Archived. 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.”. This Universe ends in another 125 billion years, at our current acceleration of expansion. The pattern for this is Jesus Himself. Two possiblities exist: either the Universe is finite and has a size, or it’s infinite and goes on forever. I'm not saying it is; I'm under the impression we don't know for sure whether it is or not. “I always regarded inflation as a very artificial theory,” says Roger Penrose, emeritus Rouse Ball professor of mathematics at Oxford University. While particle physicists have yet to directly see any of these particles, they are pretty sure they exist. “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. Rare quantum fluctuations are predicted to cause inflation to break space up into an infinite number of patches with wildly different properties – a “multiverse” in which literally every imaginable outcome occurs. But it seems to fit the data pretty well, and is what most people would say is most likely.”. One idea put forward by proponents of inflation is that theoretical particles made up something called an “inflation field” that drove inflation and then decayed into the particles we see around us today. Our mission is to provide a free, world-class education to anyone, anywhere. “Each constituent of this ‘multiverse’ could have cooled down differently, maybe ending up governed by different laws. Because we live in three dimensions, 250 times the radius means (250) 3 times the volume, or more than 15 million times as much space. Our universe is not the universe — there might be others. Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. To our small world the vastness of the universe seems infinite, without an end in sight or in our imagination. The CMB is a major source of information about what the early Universe looked like. The initial answer to whether the universe is infinite or finite is a resounding… we don’t know. “And if a bounce happened in our past, why could there not have been many of them?” says Steinhardt. ", 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. 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 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". • 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. 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. Neil Turok has also been exploring another avenue for a simpler alternative to inflationary theory, the “Mirror Universe”. The universe is finite. Both possibilities have mind-bending implications. Now, one expert believes this could be the key to life after death. In the 19th century, Doppler tried to explain an unusual phenomenon about electromagnetic waves: if and observer moves towards or … 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 … “Something had to connect those two regions of the Universe in the past. Two possiblities exist: either the Universe/ space is finite and has a size, or it's infinite and goes on forever. “I say no. 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. But even with tweaks like this, inflation makes predictions that have, at least thus far, not been confirmed. Both possibilities have mind-bending implications. 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. 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 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 that case, it is plausible that there is one in our future. Morning Edition is asking questions about the universe, part of an effort to put things in perspective. Is the universe infinite or do we say that because we have not traveled to or seen its walls yet? As the Universe expands and cools to near absolute zero, those black holes will “boil away” through a phenomenon called Hawking Radiation. Penrose’s model predicts that much of the matter in the Universe will eventually be dragged into ultra-massive black holes. 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. 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. 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. He theorised there could have been more than one Big Bang which leads to many universes, and ours was simply lucky. 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. 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. Next came “the graceful exit”, when inflation stopped. “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. 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 possibilities have mind-bending implications. 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. Or, the Big Bang might be a transition point in a universe that has always been – and always will be – expanding. I'm not saying it is; I'm under the impression we don't know for sure whether it is or not. 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. If the end of the universe us the big rip then either if us could be right but I guess we won't live … Now only the Flat Earth people believe that the Earth is flat. IF the universe is infinite Thread starter Oldfart; Start date Sep 23, 2010 Sep 23, 2010 We won't be in a state of dreamlike consciousness, but we will fully exist in body, mind and soul. If the end of the universe is the big freeze then it could prove that yes the universe us infinite. Steinhardt, who was one of the original architects of inflationary theory, ultimately got fed up with the lack of predictiveness and untestability. [1] An actual, or completed, infinity seems to be literally a contradiction in terms; it seems to entail an end of something without an … Is The Universe Infinite . “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. So there would be an infinite number of galaxies and planets in an infinite universe. Khan Academy is a 501(c)(3) nonprofit organization. A infinite universe, with infinite matter implies infinite possibilities. Other times the force is too strong, and the universe expands so rapidly that the laws of physics are entirely convoluted, and nothing has a chance, especially life. "and the observable universe in finite," It is finite until The End, then it is entirely gone. Because there are a finite number of possible universe histories, there are an infinite number of occurrence of each one. Posted by. Without some mechanism to even out the temperature across the observable Universe, scientists would expect to see much larger variations in different regions. Sort by: Top Voted. I asked this last night but didn't get much of a response. 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. It’s not a particularly dramatic ending, although it does have a satisfying finality. 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. No matter if the Universe is infinite in time and space, nothing impossible can occur. I asked this last night but didn't get much of a response. When hyper-massive black holes collide, the impact creates a huge release of energy in the form of gravitational waves. “At large scales, it is not chaotic. This is one big motivation for some recent finite universe models, e.g. "If time is infinite," Time is finite. Sometimes it's too weak, and the universe implodes again before anything can form. … 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 Universe will become a cold, uniform soup of isolated photons. 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 problem here is that there's no uniform way to apply probabilities to an infinite, expanding universe. We hear from scientists who ponder what shape the universe has and whether it is truly infinite. Last I read, it appeared that it was impossible to create a completely convincing simulation of the Universe. See today's front and back pages, download the newspaper, Our expanding universe could start to contract, returning to that dense state and starting the bounce cycle again.”. 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. 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. These are 2 separate questions, and must be answered individually: 1. 2. “It’s a rather prosaic, conservative idea described at all times by classical equations,” Steinhardt says. 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? “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. ... Do you think you will eventually live again when atoms and particles form exact same universe … In the example in the article, in 22 billion years the Universe will be completely … The Cosmic Microwave Background (or “CMB”) has been a fundamental factor in every model of the Universe since it was first observed in 1965. And then you’ve got a universe really dominated by photons (particles of light).”. “The inflationary paradigm has failed,” adds Paul Steinhardt, Albert Einstein professor in science at Princeton University, and proponent of a “Big Bounce” model. Aristotle argued that there is no such thing as an actual infinity. Can infinities be nested—infinities of infinities? 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. 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. 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. 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).

It is also a tantalising mystery for physicists. If the universe is infinite, that would mean there is an infinite number of 'me' out there. The problem might have to do with the Big Bang itself, and with the idea that there was a beginning to space and time. “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. 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 … The universe is enormous and seems flat to scientists again. 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. 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 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’.”. 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. When things finally cooled enough for the first hydrogen atoms to form, the Universe swiftly became transparent. 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? However, scientists think that the universe is flat like a pancake. “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.”. 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?
