And that given the size of reality - billions of worlds, around billions of suns - it is fairly likely that if this is possible, it has already happened. And if it has? Well, then the statistical likelihood is that were located somewhere in that chain of simulations within simulations. The alternative - that were the first civilization, in the first universe - is virtually no pun intended absurd. Read More on Huffington Post UK.
