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
Outside the bounds of our universe may lie a "super" universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own.
But knowing the Universe goes on beyond 45 billion lightyears still doesn't tell us whether it's finite or infinite. One thing's for sure: the Universe does not have an edge. There's no physical boundary – no wall, no border, no fence around the edges of the cosmos.
The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there's no center they're expanding from and no outer edge to expand into anything else.
Space was created in the Big Bang. Our universe has no edge or boundary - there is no 'outside' of our universe (see question 1). It is possible that our universe is part of an infinity of universes (see question 5), but these universes do not necessarily need a 'space' to exist in.
If you traveled in a straight line, you could travel forever in time, but you'd only be able to reach a very small proportion of even the observable Universe. Everything beyond our current cosmic horizon — beyond the limit of what we can presently see — is forever beyond our ability to reach.
Can we travel between multiverses? Unfortunately, no. Scientists don't think it's possible to travel between universes, at least not yet. “Unless a whole lot of physics we know that's pretty solidly established is wrong, you can't travel to these multiverses,” Siegfried says.
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.
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.
Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.
Thanks to dark energy and the accelerated expansion of the Universe, it's physically impossible to even reach all the way to the edge of today's observable Universe; we can only get a third of the way there at maximum.
This means the unobservable Universe, assuming there's no topological weirdness, must be at least 23 trillion light years in diameter, and contain a volume of space that's over 15 million times as large as the volume we can observe.
There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
Answer and Explanation:
There is no current name for our Universe, other than simply "the Universe", although we have names for our own home in the cosmos. Earth is part of the solar system of planets revolving around our Sun. The Sun is one of hundreds of billions of stars in the Milky Way Galaxy.
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.
Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
Some theorists have even argued for more, up to an indefinite number of possible dimensions. Other physicists suggest that experimental results have thrown cold water on the case for higher dimensions, leaving us only with the familiar three dimensions of length, width and height, plus the dimension of time.

"There's really no sense of time." At the edge of the observable Universe, there's something else happening, according to Katie Mack, an astrophysicist at the Perimeter Institute for Theoretical Physics in Canada. The Universe is expanding from the Big Bang, and that expansion is stretching time too.
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.
There's a wealth of evidence that the Universe began in a Big Bang around 14 billion years ago. We can see distant galaxies racing away from each other, and the space around them is filled with cosmic radiation whose intensity and spread are consistent with that expected from the aftermath of the Big Bang.
The number of possible parallel Universes tends to infinity, but does so at a particular (exponential) rate, but the number of possible quantum outcomes for a Universe like ours also tends to infinity, and does so much more quickly.
There is currently no conceivable way to get to these if they exist, and they may only be possible, not actual. To travel between realities, they need to be in proximity. To be in proximity and not interact, they need to be incompatible. If it is a compatible universe you could travel to, it is already here.
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big ...
