It's posts like these that show you don't understand what you are talking about.Based on physics within an environment that has gravity generated by celestial bodies, black holes and planets. But what about the void of space where the same material comprising all of the celestial bodies is present but is not in the form of celestial bodies? Would gravity still exist?
Some bacteria, lichens (Xanthoria elegans, Rhizocarpon geographicum and their mycobiont cultures, the black Antarctic microfungi Cryomyces minteri and Cryomyces antarcticus), spores, and even one animal (tardigrades) were found to have survived the harsh outer space environment and cosmic radiation.
This has nothing to do with the first paragraph. You'd get less crap if you could focus on something rather than these random spews of inchoate nonsense. And try sourcing stuff before you post it since it is just unsubstantiated drivel, otherwise.So at least one animal the tardigrade is able to survive the harsh out space environment.
That said, your claim is not backed up in the likely source of this information which you failed to quote.
page 30, by the way,Although we have demonstrated that some rock dwelling species are capable of partially withstanding the harsh environment of outer space or certain parameters of it for at least 1.5 years, the data are insufficient for drawing any consequences for the likelihood of Lithopanspermia
