- shiroiuma 3y agoI did too, but my point is that even if some planet is really "close" to Earth as far as climate, it doesn't matter because it's too far to get there. I really think that it would be technically easier to just build a bunch of O'Neal cylinders here near Earth orbit, than to build ships capable of colonizing a distant planet.
