There is a possibility that the Universe is finite but unbounded - similar to the surface of a sphere; e.g. if you shoot off at near-light-speed in a particular direction, in a few trillion years you arrive back at your starting point from the opposite direction. While I can't actually visualise what that "looks like", I can just about comprehend it.
However, when I consider the possibility that the universe might be infinite and unbounded (so no matter which way you head, all you find is more universe) - THAT I simply cannot comprehend - but I have to accept that it might actually be true.
