We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
they make up a vast multiverse of possible universes. and up to 11 dimensions featuring wonders beyond a while imagination. and the leading version of string theory predicts a multiverse made up of 10 to the 500 universes. the one followed by 500 zeros a number.
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.
Alternate realities, together with alternate universes (and their own alternate realities), form the multiverse. In theory there are an infinite number of realities, ever branching with one for every infinite outcome. As of the 2370s Starfleet had records of 285,000 different quantum realities.
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
As a universe, a vast collection of animate and inanimate objects, time is infinite. Even if there was a beginning, and there might be a big bang end, it won't really be an end. The energy left behind will become something else; the end will be a beginning.
Since nothing we know of can travel faster than light, we may never be able to pass that barrier. Some ancient light from beyond the Particle Horizon may still reach us, but there's a boundary from beyond which even ancient light can't be seen called the Cosmic Event Horizon.
Georges Lemaître published a paper in 1927 that proposed the universe started out as a singularity and that the Big Bang led to its expansion [source: Soter and Tyson]. According to Einstein's theory of relativity, time only came into being as that primordial singularity expanded toward its current size and shape.
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.
Therefore, our universe is called the cosmos.
After the events of Infinite Crisis, the remaining Earths created by Alexander Luthor collapsed back together, combining elements to form one New Earth. However, the single universe was too small to contain the energy inside it and via Hypertime it began replicating—into 52 identical Universes: a new Multiverse.
The Twelve Universes (１２の宇宙, Jūni no Uchū), also called Multiverse referred to twelve massive celestial bodies which contain the entirety of the Dragon Ball multiverse, that exists into one singular universe. There were formerly eighteen universes but six of them were destroyed by the Zen'ō when he was angered.
As it stands, the universe is the largest object that we are aware of. There is nothing larger, and everything we can smell, hear, taste, touch, or see is a part of it.
It is impossible to destroy and create matter. Thus, everything that has existed still exists, and everything that will exist already exists, just not in the state(s) it did or is going to. And even if time is infinite you would not be born again.
In about 100 trillion years, the last light will go out. The bad news is that the universe is going to die a slow, aching, miserable death. The good news is that we won't be around to see it.
Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.
Pet peeve alert: contrary to assertions in some bad sci-fi, it is impossible to travel to a dimension. We can only travel in a dimension. In three-dimensional space, we can move along an x, y or z axis or some combination of those, but not to x, y or z.
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
We can't use a time machine to travel hundreds of years into the past or future. That kind of time travel only happens in books and movies. But the math of time travel does affect the things we use every day.
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
Einstein's general theory of relativity predicts that time ends at moments called singularities, such as when matter reaches the center of a black hole or the universe collapses in a “big crunch.” Yet the theory also predicts that singularities are physically impossible.
"When you see things in the really distant Universe, because of the expansion of the Universe, it takes longer for things to happen," she says. The effect is known as cosmological time dilation and it's far more powerful than the tiny time changes seen near Earth.
