The universe is huge. That means two things: 1. there is probably life elsewhere, 2. It is likely too far away to have reached us. Space is big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space. Thanks to Dr. Simon O’Toole for talking exoplanets with me! We also discussed the Drake equation but there wasn’t really room for it.
