In the Bayesian sense, I must now update my priors regarding life coming to Earth from another planet. I always gave that theory a very low probability, but now that its been demonstrated that some life can survive in space, I must admit the theory is somewhat more possible than I previously believed.
Also, does anyone know what "mm" stands for when they say these creatures are a maximum of 1.5mm long? I thought "millimeter" but that doesn't make sense in the context:
"They are never more than 1.5 mm long, and can only be seen with a microscope."
I can see things that are 1 millimeter with my own eyes, so what does "1.5 mm" mean? Could "nm" would have been nanometer, but that would be far too small, much smaller than a virus. I'm thinking they meant millionth of a meter?
