Why hasn't a space elevator been invented?
Why haven't we built a space elevator yet?
Should we build a space elevator? What are the most realistic ideas for building a space elevator? Why was the elevator invented? Could we create a space elevator using super-powered magnets? If a space elevator will be so useful and profitable, is there a cold war-like race to develop and build it going on right now? Who invented the elevator? What happened to spinning a space station to produce artificial gravity? Would a space elevator be required to be at the Equator? How was the first astronaut suit designed if no man has ever been to space then? What could have gone wrong with the SpaceX COTS Demo Flight 2/3? How did scientists/engineers get the requirements of the first space suit given that no man had been to space before? Was NASA planning on building more shuttles after 1985? Why are aeroplane wings not placed at their center of gravity even though they are only meant for the lift but have have elevators for pitching moments? Is it possible to create a space elevator using electromagnetic force fields? What happened to the space ladder program? How was the International Space Station built? When is a new commercial building required to put in an elevator? Why has the international space station not grown exponentially over the years? What material is the the exterior of the space shuttle made of? What determines how many elevators a building will have? Why doesn't NASA build a spaceship and leave it docked in the ISS to be used for exploration missions? Industrial Design: Why don't cars have "wing" windows anymore? Why doesn't NASA design new versions of the space shuttle? Why don't we launch trash into space? With advancement in technology, why doesn't NASA plan to build a cheaper to operate space shuttle? Why do a lot of elevators have mirrors on the interior? With all the things we are sending into space, don't we run the risk of making the earth smaller? Could we, at some time long ago, have discovered space travel? Why don't airplanes have bigger windows? Why can't we send the International Space Station (ISS) into deep space instead of burning it up in the atmosphere?
