Steven Vogt was asked what he thought about the chances of life
existing on Gliese 581 g. Vogt was optimistic: "I'm not a biologist,
nor do I want to play one on TV. Personally, given the ubiquity and
propensity of life to flourish wherever it can, I would say that, my own
personal feeling is that the chances of life on this planet are 100%. I
have almost no doubt about it."
