If that is indeed the case then no matter how fast 2 particles are moving away from each other they can keep getting further and further apart forever and never meet each other again. And that's what a universe with infinite spatial extent means. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
