We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
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.
The total size of the universe is unknown. Recent research suggests it may be infinite, implying that there could be an infinite number of galaxies. However, there is a limit beyond which we cannot see; because light from beyond has not had time to reach Earth since the Big Bang.
Quilted. The quilted multiverse works only in an infinite universe. With an infinite amount of space, every possible event will occur an infinite number of times. However, the speed of light prevents us from being aware of these other identical areas.
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction.
For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!
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.
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.
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.
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.
We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
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 shared universe, unlike the original DC Universe in comic books, has yet to cross over its common plot elements, settings, and characters. The reality of Earth One is designated as Earth-1 as part of the DC Multiverse.
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.
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.
The Sun is one among hundreds of billions of stars in the Milky Way galaxy, and most of those stars have their own planets, known as exoplanets. The Milky Way is but one of billions of galaxies in the observable universe — all of them, including our own, are thought to have supermassive black holes at their centers.
Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down.
According to the Book of Genesis, God created the universe - and all the heavenly bodies, the sun, the moon, and the stars - in six days. But according to contemporary cosmologists the universe began with a great explosion known as the Big Bang, after which the stars and galaxies slowly formed over billions of years.
According to this model, there are only three dimensions of linear direction: variations of up, right, and forward. In other words, height, length, and width. But even with all the practicality of Euclid's model, the concept cannot be mathematically proven, opening the doorway to another fourth direction.
So you don't necessarily have to look up but you can look out and see heaven. Heaven is a fourth dimension if you will," he tells Walters.
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.
According to NASA, time travel is possible, just not in the way you might expect. Albert Einstein's theory of relativity says time and motion are relative to each other, and nothing can go faster than the speed of light, which is 186,000 miles per second. Time travel happens through what's called “time dilation.”
In the Discursive Condition, then, time is finite because it can exist only as a dimension of events and is not an infinite and neutral envelope for them.
Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
