Is the universe infinite? If not, then what's outside it?

Can we have an infinite universe for example? The answer is no, the universe is finite. Stephen Hawking in 'A Brief History of Time' (1989 page 44) describes the universe as being "finite but unbounded". The simplest answer is that as the universe is known to be expanding, it cannot possibly be infinite. To be precise, the dictionary definition of the word universe is "all that is. The whole system of things." In this sense the universe is not expanding into anything other than itself, for whatever it is expanding into is part of the universe, there being nothing else but the universe. However, for the sake of simplicity, I am referring only to our Big Bang expanding universe as 'the universe'. (Even if you happen to disagree with the Big Bang theory, the term 'universe' will still have the same meaning here, as it refers to 'our' universe only, and does not include whatever may or may not exist outside of it.)

As the definition of Universe is "the totality of all that exists", there. by definition, can be nothing that exists beyond 'universe' as if anything does exist, it is part of 'universe',
Now, there is a theory that multiple universes exist, but they do so in other dimensions or realities. Our universe though, is all which is contained within our own plane of existence. It includes anything that can be reached by any conceivable means of travel.

On the boundries of this universe is the boundry of another universe. If you go there, there are those viewing machines like they have on top of the Empire State Building that you put in a quarter and you can view your alternate self from that universe looking back at you.

There is no way to know. This is why: to see whatever lies beyond the edge of our universe (assuming something does) you would need light to travel there and back to us. Since the edge of the universe is as far as the light from our universe has travelled, some light would have to travel faster than that light to get ahead of it and return to us. Since nothing can travel faster than light, not even light itself, this is not going to happen. Therefore, there is no way to find out what lies beyond our universe.

"Universe is Infinite but bounded" as per Einstein's words.

Perhaps another universe or an alternate dimension. The Universe may go on and on forever OR our universe may be stuck in a snowglobe which is in turn stuck in another snowglobe which is in turn stuck in another snowglobe which is in turn stuck in another snowglobe which is in turn stuck in another snowglobe ...
