The Fermi Paradox is “the apparent contradiction between the lack of evidence and high probability estimates for the existence of extraterrestrial civilizations.” I don’t know if I buy this. I think the fact that we can imagine that there is life in space means that there is in fact life in space. In the end, I think the paradox comes down to this: at some point either we will take planes into space or something will come in planes from space. We just don’t know.
