Lightning Knight posted:Isn't the problem with this that even not going faster than light, one could still colonize other planets given a sufficiently large time scale (i.e. millions of years), and given the age of the universe (i.e. billions of years) this implies we fundamentally misunderstand something about the galaxy or that somehow there has not been intelligent life before us? I think his point is that it may not be practical to do it even the slow way. That entropy and interstellar radiation etc mean you just can't build a craft capable of slowboating it between the stars over a couple of centuries without it failing.

LeoMarr posted:I thought entropy wasnt such an issue because there is no heat dissipation in space Entropy used here in the sense of "Stuff wears down and breaks" Lightning Knight posted:I don't follow. Could you elaborate? That it may not just not be possible to build machines with the kind of reliability that would be required over centuries of slower than light travel. That all the fancy handwavy, basically magic, Nanotech self-repair you see in SF shows are not compatible with the actual laws of physics.

N.b. I am not definitely saying it is/isn't possible. Don't know enough to say. But it's definitely a possibility.
