Interstellar travel
On youtube’s Kurzgesagt a new video explains why humans can’t possible far outside our solar system, due the enormous distance. Only way out would be to somehow travel faster than light (ftl) which is of course currently impossible.Interesting to think about how this is ‘solved’ in science fiction stories:Warp speedOne way obvious way is to make ftl possible is something like warp-speed as we all now from Star Trek. Obvious because it’s basically you suddenly can travel faster than light due to some not in detailed explained process of the bending of light. It assumes spaces is uneven, so if you can travel somehow in a ‘direct line’ you can overcome the lightspeed-barrier. In many books and movies there’s a similar mechanism like in the later novels of three-body-problem. It’s somewhat boring as it basically means spaceships do go faster, they can go to any place in a somehow linear…
