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.
