I have my own opinions as to the prevalence of life in the Universe, but I’m curious to hear what the rest of you have to say.

What do you think: is the phenomenon of life on Earth a cosmological fluke, or is the galaxy littered with inhabited worlds? Perhaps microbial life is commonplace while multicellular structures are rare–or maybe the galactic empire is stealthily watching and waiting for us to cross a technological threshold. And, of course, there’s always the possibility of stumbling across an alien beacon.

Ready, go!
