I have to wonder if that "assumption" includes asteroids passing life between systems. That's what it sounds like, and to me, that's an absurd assumption. What proportion of asteroids will break orbit from its parent star? What proportion of those will contain any life at the beginning of the journey? What proportion of those will happen to be captured by another solar system containing a habitable planet? What proportion of those will still contain any trace of viable material after millions of years in transit? What proportion of those will happen to land on the planet habitable to that kind of life without annihilating it? I don't see how you could get 38,000 out of that.
Thats a cool pic of ISS!
How did someone manager to take a pic of that?
