If the universe is constantly expanding, as it is believed to be doing, then it would take infinite energy to expand? If all that energy came from a finite area (which the big bang theory states), then how is it possible that infinite energy can come from a finite space?

But why do you believe that infinite energy is required for the expansion? Also, why do believe that energy is conserved when a universe is created?

J Lu

If the universe expands forever, it is actually infinite in extent so a finite energy density can add up to an infinite energy. But the energy (total) of the Universe need not be conserved!
