How far can we run?
Sometimes I think about the ultimate possibilities for humanity in the coming hundreds and thousands of years. It seems like this planet will at some point in time no longer be here or habitable. The next step is going elsewhere. If we go elsewhere, how far can we go and what will stop us from doing the same thing over and over until there is no where to run? I am not trying to be negative here but I guess that there must have been some ancient Greeks or Egyptians that must have imagined where humanity would be now after 5000 years. I guess my question is where is the ultimate destination for humanity?
