Reply to comment by Zak_The_Slack in [WP] Faster than light travel has been proven impossible, that's why humans are so surprised when aliens turn up. Not as surprised as the aliens on the generational ship who say the planet was void of life when they set off, following a missile they had sent to wipe out the dinosaurs. by Wrooof

Didn't you mean "Be glad you did NOT meet..."?

And the missile the wiped out the dinosaurs fell 65 millions years ago, not 165.

100 million years later is enough time to colonise the galaxy at an acceptable rate I think we would either be long dead or the aliens would already be dead, known about or enslaved

Yea, but it was the only explanation I thought of.

Why would they wait 165 million years to start traveling to Earth, (assuming the missile goes the same speed as the the ship) to colonize the place?

Maybe they wanted to let Earth "cool down" after a total extinction event, but I doubt that 165 million years is even enough.

The missle accelerated faster to a fraction of c while the generational ship ramped it's speed up (and then down) slowly in comparison, since it was humungus in size?

That wouldn't make much of a difference over 65m years, since even at 1g acceleration you get to 10% of c in a few decades.
