Hello. I wonder what do you think about universe. What is universe? How big is it? What's its shape, form? Does it have borders? What's behind those borders? Who created universe? :confused::);)

dijana, you appear to be quite young, and I don't think this is a homework question. You are just curious. No one could possibly know how big the universe is, dijana. It is infinite. Nor could they know its shape, form, or borders. Why don't you Google 'universe' in wikipedia and find out what they say. Possibly, the same thing.

Tick

Well, no one can say for sure since no one actually knows what it is, where it ends, if ever it really ends...

So, you have different people believing in different things. For example tick said it is infinite. Other people might say it is still expanding, others would say that it has got it's limits, etc.

There are too many different views about the universe. What you can do is make research of your own, and fin the answer which seems satisfactory to you. If you happen to think of something that nobody mentioned before, but you are quite convinced the universe is like that, then it's good, you may be right.

But keep in mind that nobody knows what it is exactly, and many answers you find might be wrong, or be considered wrong by some people.
