I don’t think interstellar travel necessarily implies much better tech than we currently have. I mean, Project Orion style nuke-powered spaceships can get you there in a lifetime but unless you wanna nuke your colony whenever someone needs to leave you still might be stuck on the surface.

- marcosdumay 4y agoIt's a non-trivial number of nukes on every single launch. If it becomes popular, it will have a very noticeable effect on a planet. Nuclear propulsion isn't the only alternative we have for reaching low orbits. Land-powered rockets are probably much better, and there is always the odd high-elevation rail or space elevator (but those get bad fast on large planets).
