How Would a Real Space Elevator Work and Is It Even Possible to Build?

Kurzgesagt ponders the question of whether space elevators can be built and answers it as only they can. It’s fascinating to learn about the (obvious) benefits of having a space elevator—sending things to space becomes much, much cheaper!—but even if it’ll take forever and a half to build this mythical 22,370-mile structure (which we can’t yet with our current technology), it might be worth it just to better explore our options for exploring space.

The one factor that would prevent a practical space elevator is all the junk and other satellites that are up there now. I would think there would be a huge chance of something up there colliding with the tether. Satellites may be able to maneuver out of the way, but lots of stuff up there can’t.
