Q: Aliens. Are they out there?
A: I’ve never been able to decide on this, but at the moment I am leaning towards yes, although quite possibly in some format that we would find quite disappointing or incomprehensible. Certainly no Klingons or beautiful green women. Arthur C. Clarke said, either we are alone in the universe or we are not, and either way the answer is terrifying – but it’s also quite amazing.
