Is the universe infinite?
Well we can't be quite sure about since we haven't discoverd all of it and we don't know everything about it but of course there are theories and observations about it. Like we know that universe is expanding, thanks to edwin hubble's works (you shoul really search about him and his work's) and the galaxies are getting far and far away from each other because of this expansion. Probably you've heard about The Big Bang Theory (there is even a TV show named after it!), according this theory, at first the universe was very very tiny, and it started expanding after a kind of explosion we call "the big bang" an its still expanding. Some scientists say it will keep expanding to a some point that all the galaxies will be pushed away so far from each other that the univers will be in a like "frozen" state. Not of course the matter will freeze but the galaxies will stop at some point. And some say the universe will collapse in some point because of the gravitational force. Well these things I wrote are not enough to understand what's going on in the universe. You should search yourself. Especially about the big bang theory and edwin hubble. I hope this was helpful.
