How is bacteria in comets and asteroids relate to new sicknesses on earth?
Because if it hits the earth


those bacteria will travel down to earth and cause new diseases and bacteria.
Reply:Well, the problem there is that we have to assume that the bacteria etc can survive in the coldness of space or the het of a fiery comet.


That would be like your head surviving in my a s s while I fart.
Reply:Humans (and other animals, for that matter) would probably be weak against the germs because they have never encountered them before and have not had a chance to develop an immunity. That's part of why most people don't get the chicken pox more than once...because we've had so long to adapt to the disease.
Reply:if there is a unidentified bacteria on a piece of space rock or comet that manages to get past the atmosphere then it is a bacteria that humans haven not been exposed to and there for do not have an immunity to it yet.
Reply:to this point in time there has never been a bacterium or virus found on either a comet or an asteroid so the effect would be none.
Reply:We don't have samples back from comets or asteroids yet. And it's not at all likely that bacteria could remain viable in the vacuum of space.
Reply:It doesn't. Only if the comet/asteroid hit earth. Then the bacteria would've had to survive the freezing depths of outer space, survive without a host, and the several thousand degrees heat when it entered our atmosphere.
Reply:they all came from the same momma
