- What are you assuming about population growth rates here? If you
- assume exponential growth, even a HUGE finite size can be overwhelmed
- before you know it. Even if the universe were infinite, however, the
- total size of the universe is not the real limiting factor. The real
- limiting factor is the speed of light. If you can only move into new
- space at the speed of light, the volume of space you can use grows as
- the cube of the amount of time at most. If the population is growing
- exponentially inside that volume, it may very quickly catch up.
