Is it possible there has been more than one Big Bang? Or that there could be another Big Bang? Or if there was a second Big Bang would we ever even know it happened?
Possibly, we don't know what came before the Big Bang. They could happen over and over or just once.
Hi Fraser, I have a problem with the idea that when we have the technology we will send self-replicating robots through-out the galaxy. To what purpose? In advance of human colonization? To gather raw materials? To make computonium? I'm not sure what the end game is in this scenario. Could you explain.
Computronium! Love it
