B Size of the universe

  1. Jan 2, 2017 #1
    If the universe is infinitely large, has it always been so? If space and time did not exist outside the big bang, was the universe at the time of the big bang infinitely large? Does this suggest the vacuum of space was infinitely large and the big bang is expanding within it?
