Is the universe infinite?

I assume the first one would be the best explanation out of all three. I definitely do not agree with the idea of finite space though. It just doesn't seem to be right, for some reason. Although the first might be the best solution out of the three as separate solutions, #1 and 3 combined would create the solution that is accepted today.
Actually, #3 is the direct solution, with the finite age of our universe necessarily stemming from the fact that it's expanding. The light travel time isn't really significant, in other words, but the redshift is.
