?Beyond the universe! What is beyond the edge of the universe
The definition of beyond the universe implies that the universe has an edge, but scientists aren't sure if such a thing exists.
The answer depends on how one looks at the question, says Jesse Emsbach, a contributing writer to Live Science.
Someone asks: Can you go to a place where you can look "beyond the universe" the way one can look over a cliff edge or look out a window to see the outside of a building? The answer to this question is probably no.
The implication is that there is no 'edge', there is nowhere to go where the universe ends, and a person can look in some direction and see beyond the universe.
Big universe:
Paul M. Sutter, an astrophysicist at the State University of New York (Stony Brook University) and the Flatiron Institute, and author of How to Die in Space also provided an answer to this question.
Souter says in an article on Space that if the size of the universe is unlimited, then there is no need to worry about this question.
And he adds that there is certainly a part of the universe that is still outside our observation, as the universe is very old, and nothing can be known about the universe except through light, and despite the speed of light at which it travels, we did not receive light from every galaxy throughout the history of the universe.
The current width of the visible universe is about 90 billion light-years, and beyond that boundary is supposed to be a host of stars and other random galaxies, but beyond that we can't speculate.

Expansion of the universe:
Mac says that the actual size of the visible universe is 46 billion light-years in any direction, and although the universe began only 13.8 billion years ago, this still puts a limit on the size that humans can see. It is called the "visible universe."
Anything outside this ray of 46 billion light-years is not visible to the inhabitants of the earth, and it will never be visible, because the distances between objects in the universe increase at a faster rate than the arrival of light rays to the earth.
Moreover, the expansion rate of the universe was not uniform. For a short fraction of a second after the Big Bang, there was a period of accelerated expansion called inflation, during which the universe grew much faster than it is now. Entire regions of space cannot be seen from Earth for this reason. .
Mac adds that assuming the occurrence of inflation, the universe is actually 1023 times larger than the 46 billion light-years that humans can see, so if there is an edge to the universe, it is very far away and Earthlings cannot see it and they will never be able to see it.
