Is the universe finite?
Was the big bang located at a single point and did it involve a finite amount of energy?
Is space like the surface of a balloon (except 3D instead of 2D)
that is gradually expanding?
Does it have positive curvature so that if you continue along a straight line you might get back to the same place?
Are cosmologists at odds about the finiteness vs. infiniteness of the universe or has a consensus developed based on reliable observations?
I want to know what PF posters think so I'll try to construct a poll---this is my first attempt at a poll.
