It is impossible to prove, except with no friction in space due to the lack of gravity, fungal/bacterial spores simply float away. This could be why astronauts aboard the Russian space station Mir witnessed large, fungal/bacterial formations seemingly all over the spacecraft.

Four things the head of astronomy at Harvard Prof Avi Loeb says makes it highly unusual
1. its unusual trajectory coming from outside of the solar system
2. flattened shape like a pancake or pointy sails, which didn't align with typical asteroids or comets.
3. its incredible high speed and peculiar acceleration upon entering our solar system
4. Its ability to inexplicably leave our solar system with no obvious trail of gasses to act as propulsion...

the hydrogen gas hypothesis is grasping for straws since this actually can't be proved.

You would think that they would patch the holes so that the oxygen wouldn't all leak out.

Seriously, it shouldn't be any surprise that there are fungi and bacteria on a space station occupied by people. No surprise at all. If there weren't any fungi and bacteria, that would be surprising. That they are there should not be at all surprising.

Remember the "oumamua" interstellar visitor? It is going very fast -- something like 50 to 60 miles per second. At that rate, it would take many thousands of years to arrive from another planet with life and for that to happen, the "spores" would have to be accelerated to very high speeds by some mechanism that seems little more than science fiction.


A world authority - Prof Avi Loeb says oumamua could easily be millions of years old given the antiquity of the universe could be a relic from a long extinct civilisation traversing space before entering our solar system. With that in mind the spores might hitch a ride on comets or asteroids or objects like oumamua from other galaxies.


Do you really want to replace science with speculation?

It's one of the risks in sending probes crawling all over Mars, any contact with water and there's potential for cross contamination from earth.

It's not speculation. It's an alternative explanation that remains scientifically plausible as no conventional explanation currently makes sense.
