MULTIVERSE
All that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. Multiverse, a hypothetical collection of potentially diverse observable universes, each of which would comprise everything that is experimentally accessible by a connected community of observers. The observable known universe, which is accessible to telescopes, is about 90 billion light-years across. Linde and Vanchurin have applied some reasonable rules to calculate that the number of universes in the multiverse and have totted it up to at least 10^10^10^7. Our universe is but one in an unimaginably massive ocean of universes called the multiverse. If that concept isn't enough to get your head around, physics describes different kinds of multiverse. The easiest one to comprehend is called the cosmological multiverse. A universe is everything that has been and will be observable from a certain point. The universe's shape is seen as a sphere or a regular dodecahedron (a twelve-sided polyhedron). The concept of the multiverse arises in a few areas of physics (and philosophy), but the most prominent example comes from something called inflation theory. Inflation theory describes a hypothetical event that occurred when our universe was very young less than a second old. Multiverse Originated by US physicist Hugh Everett in the late 1950s, this envisions our Universe as just one of numerous parallel worlds that branch off from each other, nanosecond by nanosecond, without intersecting or communicating. If you are an advocate of a multiple big bang multiverse, then that would mean that leaving our universe to travel to another would be just as impossible as travelling back to the time before the big bang that resulted in our universe even happened. No matter you've worn them both, in two separate parallel universes. The multiverse theory may be dressed up in scientific language, but in essence, it requires the same leap of faith. George Ellis, writing in August 2011, provided a criticism of the multiverse, and pointed out that it is not a traditional scientific theory. Brian Greene: A Physicist Explains 'The Hidden Reality' Of Parallel Universes It is possible that there are many other universes that exist parallel to our universe. Theoretical physicist Brian Greene, author of The Elegant Universe, explains how that's possible in the new book, The Hidden Reality. Multiverse theory suggests that our universe, with all its hundreds of billions of galaxies and almost countless stars, spanning tens of billions of light-years, may not be the only one. Instead, there may be an entirely different universe, distantly separated from ours and another, and another. One of the topics Hawking tinkered with toward the end of his life was the multiverse theory the idea that our universe, with its beginning in the Big Bang, is just one of an infinite number of coexisting bubble universes. The concept of the multiverse stems from the big bang theory Albert Einstein's once controversial, but now widely accepted, idea that the universe instantaneously expanded from a tiny point called a singularity. In physics, the word multiverse normally refers to one of three distinct and largely unrelated proposed physical models for the universe. None of which has been tested or confirmed by experiment, by the way. The three multiverse models are type one, bubble universes or baby black hole universes. According to a mind-bending new theory, a black hole is actually a tunnel between universes a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes. Than what if there is a bigger theory, yes there is and that is the megaverse. A Megaverse is a collection of multiple different Multiverses, either a finite or infinite amount of them, usually each having different properties and interuniversal laws, such as different cosmic events being possible, such as Big Booms. Megaverses are the third unofficial layer of Archverses, following Universes and Multiverses. While our Megaverse is 6.521 undecillion light years big, most Megaverses are significantly bigger than Multiverses! By Xeyons, their physical laws take effective in covered Multiverses, consisting of some laws from Inforium.
