The Moon Tube
Recently, researchers at Columbia University and Cambridge University announced that we can just build a space tube connecting the Earth to the Moon to help cutdown on space travel time and cost. They said this really casually, like it was a completely normal thing to say. Sure, they called it a “Spaceline” (which is, admittedly, much better marketing), and it’s actually a space elevator. But let’s be real — that’s a tube.
