Random question. Why haven't we made a spinning space station yet to simulate gravity? Would fluids still work? Does the spinning actually work?
1/ is hard to build in space (big pieces that need to be assembled)
2/ needs to be big enough not to make everyone sick (the diameter must be quite large for the gradient of gravity not to be too noticeable)
3/ Not very useful when one of the main points of having a space station is to do ~zero g experiments
