If the universe is expanding,?

Question

Then is there nothing on the other side. And what is nothing?

Answer 1

According to current theory, the universe is infinite, but, caves in on itself, kind of like a donut or funnel. So, if you traveled far and fast enough you would catch up to yourself. These theories were propageted by Einstein, and accepted by most scientists.

Answer 2

I am uncertain what you are driving at in this question. Yes, the Universe is expanding. We can only see part of it out to a distance of about 40 Billion Light Years. Our best optical and radio telescopes sort of fail us at that point. We can't get any useful information from them any farther out than that. This is not a limitation of space...rather a limitation of our current technology.

Now, seriously, how can you possibly expect someone to tell you what is beyond that, or explain something that they cannot even see to you? You don't expect that. Because, any answer you get will be a guess, some cute joke, or a theory.
Theories are a dime a dozen, and with one in hand you will starve before it does you one bit of good.

What "other side?" What makes you think there is a front and a back to the Universe? YOU SEEM TO BE TRYING TO EXPLAIN THE UNIVERSE IN EARTH BOUND TERMS.
Wake up. The Universe is vast beyond belief, and does not fit into categories which are suitable for earthbound logic and contemplation. You must first comprehend the vastness of space before you can ask intelligent questions about it.

Nothing is the "absence of everything, even air." You already knew that, but insisted on asking as if you held some special secret knowledge that other people do not know. Good. All of us are most exceedingly happy for you. Next I expect you will ask what will happen after the end of everything, or what was here before the beginning of everything. Those are meaningless questions also. Nobody knows. So don't waste our time.

Have a nice day.

Answer 3

There is no "other side" according to the expanding universe theory. It is difficult to explain because you have to think in more than 3 dimensions. The best explanation I have found is to imagine that you are a 2 dimensional being on the surface of a balloon. There is no up, away from the balloon, or down, into balloon. There is only the surface of the balloon. So in your 2 dimensional world there is no edge to the universe. There is no other side. But if the balloon is inflating then your universe is expanding.

Answer 4

I'm not sure what you mean by other side, but the universe is always expanding because there is no force to stop their momentum. Nothing is probably where no galaxies or any matter whatsoever has reached leaving as an empty area of space with no molecules or forces to give it characteristics.

Answer 5

You have a better chance of finding an answer to a question like this in a philosophy or religion text than in science. We haven't found answers to these questions yet. That doesn't mean that it's impossible to find them. But no one has a scientific answer yet. I make the distinction because plenty of people have answers, but none of them are provable through experimentation and the scientific method.

Answer 6

It is impossible for us to imagine the "nothing" beyond the universe, if we think of it as a 3 dimensional volume of space, which it isn't, or else it would be part of our universe.
You need to think outside that box!
