Is the universe infinite?

  1. Apr 18, 2013 #1
    Hello, i have been watching documentaries and reading papers about the universe and i've noticed that there are many opinios on the size of the universe. Some say it's infinite and some say it's not. But if it's not, then it has to have a center. So my question is, is the universe infinite or does it have a center?

    It isn't true that if it is finite it must have a center.
