Re: Bacteria on the outside of the International Space Station
#2I can't help but keep wondering if "life originated on Earth" might not be the last geocentrism.
It's only speculation at this point but it's one I've harbored for many years. Part of this is because of how common we've found organic materials to be in the universe, and part of it comes from how poorly other geocentric ideas have fared.

I'd love for this story to be true but it's almost certainly not, the bacteria must be terrestrial.
Cf. https://en.wikipedia.org/wiki/Tersicoccus_phoenicis "It has only been found in two spacecraft assembly clean room facilities..."
Maybe it's not T. phoenicis but it's not ET.
(However, if it somehow turns out to be alien, that seems to be to imply that interstellar space must be swarming with bacteria, yes? For the ISS to have encountered some already?)

Sure, but we aren't holding to this form of biological geocentrism for no reason. We've never seen any definite proof of life on any other planets. Given that science is an evidence-based methodology, it makes sense that we would assume Earth-based life is the only model of life until proven otherwise.

You're probably right in this case, but as for the last part consider that the Earth is a gravity well and the ISS has been in space for a very long time. Earth is going to draw in particles and the ISS has had plenty of time to catch them.

This theory is called panspermia for those who are interested.
Re: Bacteria on the outside of the International Space Station
#7Sounds slightly surprising, but the exterior of the ISS is not a sterile environment. There are thousands of ways terrestrial bacteria could have ended up there. I guess the interesting thing is that the bacteria seem to be able to survive the extreme environment. But that's hardly a new discovery about bacteria.

if we wanted to be perfect logicians we would assume neither but believe the geocentric case to be a likely possibility.
Re: Bacteria on the outside of the International Space Station
#9The suggestion that the bacteria is extraterrestrial in origin is absolutely ridiculous. Much, much, much more research is necessary before such a claim can be made. The speculation on Shkaplerov's part is hugely unprofessional.

What's there around ?
solar rays for sure. Enough gazeous particules ? but that's it isn't it ?
