Given the right similar starting conditions in the DNA... It could be interesting.
What surprises me is that life can survive these trips. A rock ejected from the Earth would have to have tremendous heat during the escape velocity. Science is fascinating.
- mtdewcmu 13y agoThat's what I was thinking. That piece of rock must be very hot as it's flying out into space from a violent explosion. At least, that's how I picture it. It seems odd that the article was concerned about the danger of space itself, but never mentioned the exit from earth. Science is very fascinating, but this phenomenon of life successfully leaving earth and arriving on other planets has never been demonstrated, so it's more idle speculation than science.
- mathattack 13y agoI think they've at least seen them survive in space. I recall reading stories of microbes surviving near absolute zero. Bacteria and spores could survive a lot, but I would think they would have to be inside a mighty big rock to survive the heat.
- mtdewcmu 13y agoSome microscopic organisms are said to have survived exposure to space. But just because some of the pieces have been shown to be plausible, doesn't justify accepting the entire scenario.
- mathattack 13y agoI agree with you. I think this is a good statistics exercise too. What's more likely? That life emerges spontaneously in multiple spots of space, or that life survives inter-planetary (and perhaps inter-solar system) journeys?
- mtdewcmu 13y agoYou couldn't possibly answer that.
