Fun idea: If you have an interstellar colony spaceship that takes (in total) 100 years to replicate and fly to its destination star (assuming the avarage distance between stars is 5 light years and the spaceship flies at 0.1c). It would (in theory) take less than 4000 years to colonize all of the milky way. That, without FTL.

And you could potentially speed it up if you can somehow build more than 2 within the 50 year replicating time.

Sort of screws with my mind considering it would take 1 million years for a .1c ship to cross the entire galaxy, but mkay i geuss?

Considering we went from smashing rocks to Landng on the Moon and having the ability to synthesize almost all chemicals in 1 million years, i don't see how we cant colonize the entire galaxy within 1-10 million years.

This would make a great Sci-Fi scenario.

Just speculation however.
