When colonizing space there are at least the problems for humans:
1 – Space is a vast irradiated wasteland hostile to life.
2 – Humans would need the equivalent of a large, hollow, rotating asteroid, and some sort of drive to move it.
3 – Enough people for a colony: > 1200, but more is better.
4 – A vast store of supplies for during and after.
5 – Virtual immortality AND hibernation ability
6 – As near to perfect recycling as possible
7 – Energy to supply humans and the drive
8 – Movement even at one constant G of acceleration would make colonization possible, but at high speeds, despite the vast emptiness of space, impact with anything would be catastrophic.
9 – Yes there are lots of planets but how many:
… a) are around a class G star
… b) in a relatively low density (safe) arm of a galaxy
… c) have large outer planets to protect it from asteroids and worse.
… d) are in the habitable zone
… e) aren’t tidally locked
… f) have a rocky, watery, surface
… g) a molten core creating a magnetosphere
… h) that together are safe enough long enough to develop life
… i) have evolved an atmosphere of nitrogen oxygen
… j) and are at least relatively free of hostile elements, geology and life forms?
