One can never get around the infinity problem. If the universe is finite, what lies beyond its boundaries? If the universe began in a certain place and time, where was that place and what was that time? If the universe will end, where will it go and what will be after it? The only answer there can be to all these questions is: Infinity. The universe, however one defines it, must be infinite in space and eternal in time. There is simply no other satisfactory answer.
