Comment on If a Space Elevator became a reality, wouldn't the cable act as a kind of wick for all of the unfiltered radiation from outside our atmosphere?

  Dearth means “a striking lack of,” as in “dearth of evidence.” (No evidence)

    It was supposed to say “death and” autocorrect had other ideas I guess.

      Its still funny to read this as you having a concern about the striking lack of distruction caused by space elevator collapse. Maybe the elevator debris all got thrown into orbit?

      Ooh, that makes more sense. Auto correct is getting shittier by the day. I’ve got a new conspiracy theory that it’s a push to get us to use voice to text more, to help train our robot replacements.

  By the necessities of its design a space elevator has to reach geostationary orbit, which would make it tall enough to wrap around the planet twice if it fell. Wouldn’t really matter if you built it on a west coast or not.

    A geostationary orbit is ~35,000km from the surface of the earth. The circumference of the earth is ~40,000km. It can’t wrap around once, nevermind twice.

      Ah thanks, I was a dingus and looked up the diameter instead of the circumference. Still doesn’t really matter where you build it. No matter what it’s fucking up a a good portion of the equator if it falls.

        It still can’t really fall. It’d be moving incredibly fast sideways. Fast enough to miss the Earth for a while. Geo stationary orbit is the point where orbital speed matches Earth’s rotational speed, so if it’s anchored at the ground, then it’s at orbital speed if at GEO. The higher the orbit, the slower the orbital speed. So using a higher orbit to maintain tension means it’d be traveling beyond escape velocity, held down by the cable. A break would release the mass into the solar system

      And not all would fall. Part of it would be launched outwards by inertia.

    Actually, a good ways passed geostationary orbit if I remember correctly. It needs centrifugal force to keep the cable taut, since it won’t be supporting its weight from the surface.
