However it pans out, surely we are going to have to find a way of traveling faster than light if we even want to consider exploring our galaxy, let alone the universe. I can't recall exactly what I was watching on the Discovery Channel but on this program they had identified this planet which could possibly support/host life, this planet is considered our closest possibility of finding life and is a mere ([surrender]) 100 light years away. Tiny in the scheme of things though. So even if we could travel through space at the speed of light it would take us 100 years to get there... and this is our closest relative!
