hey. do any of you no about why gravity on earth is stronger than in space? that isnt really my question, and I no the closer the objects, the more pull force there is, but do u no if, and if so, what would be needed to be done to create an environment on earth (like a room) thats weightless like an environment in space? what kind of changes would need to be done and all? besides the elevator trick, any ideas on what has to be done?
