It is a problem when you dismiss theories or ideas without even bothering to read about them, especially in a thread about the scientific method. You question established science yourself, but seem very quick to dismiss an idea before investigating whether there is actually science behind it. Well anyway, we travel through space, and so do ice comets. The reason I questioned this in the first place comes from high-pressure deep sea drilling. In wells with temperatures above 200°C, we could still experience ice like hydrate plugging and lost circulation if glycol was not used in the mud or drilling fluid. That made me wonder if the extreme pressure from a massive asteroid impact could eject material containing water and living organisms, followed by rapid decompression and cooling, freezing and encapsulating microorganisms before sending them into space. And in theory, yes, that is possible. The part I find interesting is living microorganisms that can survive, repair themselves and reproduce again. Deinococcus radiodurans has survived years of exposure in space and remained viable. So if an asteroid impact can eject material without sterilising everything, and some organisms become protected inside rock or ice, then the idea is not really science fiction anymore. The real question is how long they could survive the full journey and still reproduce at the other end.
