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. “I take one thing away from the observations of the last 30 years, which is that the Universe is unbelievably simple,” he says. 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 … However, scientists think that the universe is flat like a pancake. Nothing is ruled out that is physically conceivable.”. In the example in the article, in 22 billion years the Universe will be completely … But what if the Big Bang wasn’t actually the start of it all? Morning Edition is asking questions about the universe, part of an effort to put things in perspective. But there have always been shortcomings with the theory. Do the numbers of galaxies, and even of universes, have no end? Both possibilities have mind-bending implications. If recurrences occur an infinite number of times, some of those … The theory says spacetime should be warped by primordial gravitational waves that ricocheted out across the Universe with the Big Bang. 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. Do stars and spaces go on forever? The opaque superheated plasma that existed in the early moments will likely forever obscure our view. 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. Like the Big Bounce, it involves a universe that might have existed forever. 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. “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 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. If the end of the universe if the big crunch then that would toss your argument if the universe being infinite into the toilet. 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. “At large scales, it is not chaotic. that’s why most have no hair! We hear from scientists who ponder what shape the universe has and whether it is truly infinite. Every time something happens, there is a new branch created. The initial answer to whether the universe is infinite or finite is a resounding… we don’t know. But, big as that is, it still isn't infinite. Neil Turok has also been exploring another avenue for a simpler alternative to inflationary theory, the “Mirror Universe”. 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). Quantum physics also forces inflation theories into very messy territory. “The conclusion we come to is that we see these spots in the sky with 99.98% confidence,” Penrose says. Now, one expert believes this could be the key to life after death. Shredded and extruded back into our container Universe. So what are your thoughts? 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. Join one million Future fans by liking us on Facebook, or follow us on Twitter or Instagram. Two possiblities exist: either the Universe is finite and has a size, or it’s infinite and goes on forever. 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. But it seems to fit the data pretty well, and is what most people would say is most likely.”. If there is a boundary to the universe it must be finite. “I always regarded inflation as a very artificial theory,” says Roger Penrose, emeritus Rouse Ball professor of mathematics at Oxford University. Both possibilities have mind-bending implications. It’s not a particularly dramatic ending, although it does have a satisfying finality. 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. When Jesus died on the cross and was laid in a tomb, His physical body was completely … When hyper-massive black holes collide, the impact creates a huge release of energy in the form of gravitational waves. However, the Cosmos is infinite, see: answer to Does anyone really believe that the cosmos was caused by a "big bang"? The pattern for this is Jesus Himself. • 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. Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. Donate or volunteer today! 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? 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. Our expanding universe could start to contract, returning to that dense state and starting the bounce cycle again.”. Read about our approach to external linking. It is not random. ”It's the one I teach in my classes. 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”. [1] An actual, or completed, infinity seems to be literally a contradiction in terms; it seems to entail an end of something without an … That’s possible but not likely. I have a hard time believing that the universe is infinite.  “That’s the number of years or more for the really big ones to finally evaporate away. 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. what do you think “Each constituent of this ‘multiverse’ could have cooled down differently, maybe ending up governed by different laws. Infinite means .. limitless or endless in space, extent, or size; impossible to measure or calculate, so I could say yes the universe is Infinite. All of these theories sit outside mainstream cosmology, but all are supported by influential scientists. 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. And this would not only apply to you, but every other person, animal plant, atom, molecule and everything else which has ever existed in the history of the universe. Aristotle argued that there is no such thing as an actual infinity. 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 Mirror Universe offers all that – and might also solve one of the Universe’s big mysteries. “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 usual story of the Universe has a beginning, middle, and an end. The universe we live in may not be the only one out there. A infinite universe, with infinite matter implies infinite possibilities. 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.
