I love these studies! They prove beyond a shadow of a doubt that without space travel Humanity is pretty much doomed. I can’t help but think of Star Trek. In that fictional universe there is no want, no need, Earth is a literal paradise. I wonder what would happen to that Universe if you kept everything else the same but eliminated warp travel from the story.
You’d have Universe 25. It wouldn’t be pretty. HA HA HA.
So what is the most important thing in the Star Trek Universe? Warp Travel. Beyond everything else. LULZ.
