Last time it got to the end without me getting a chance to ask my question. This time at the Science Cafe, mine was the first question: 'What do you make of the Fermi Paradox?'. The speaker's answer was that there are other civilizations, but they're all too far away. I think that the various answers to the Fermi Paradox are interesting, but I find none of them convincing. What's your answer to the Fermi Paradox?
