Universe is finite or infinite?

Re: Universe is finite or infinite?

@queer

not to mention cosmic background radiation is contained within our universe, not what lies between multiverses as ajazali seems to think. i recommend picking up a book on modern physics before asking such questions on a forum - no one can direct you if you dont have the fundamentals right.

@Theorist

Huh? Did you read what you wrote here? CMR only proves there was some sort of a beginning, a BIG BANG. It doesn’t provide many clues to what the shape of the Universe might be. There are different mathematical models to explain possible shapes of the universe. We don’t really know but there are many theories. One of which is probably right but we can’t be sure unless we could observe it and maybe somehow test it. For us, finite may be as good as infinite since we can’t observe or test it yet. No, it’s not a belief. It’s called Science. It evolves, grows, and improves with time and brilliant minds.

If you people have read yourself what you are suggesting me then you should answer my questions. If you have not then how can you be that sure on what you say? Its either you don’t understand what you have read or it looks like an attempt to knock out the questioners.
Its pretty simple. Value of density of Universe is equal to value of critical density means universe is flat. Where as Theorist gave a video with theory of shape of earth. If its flat how come you say it doughnut shaped?

Maybe it annoys you more, I am almost sure that you people dont know that its determined or not that un-observable universe exists. But you can claim what is beyond the universe. strange. Now again if you have read what you suggest me then answer how come you know what is beyond the universe where you still have to know about un-observable universe?
