      i agree with your sentiment completely, just to point out a small technicality:

      space elevators aren’t technically feasible. i’ve done the calculations a while ago and practically, the weight of the space elevator itself would be so much that it wouldn’t be able to carry its own weight. remember that it would essentially be a tower several hundred kilometers high. the highest buildings on earth today aren’t even a single kilometer high.

      i believe in spaceflight though
