If you were to take a blimp like structure and instead of filling it with hydrogen, or helium, or hot air, you instead "filled it" with vacuum, that is you removed everything from the inside (think mercury vacuum), would that structure float in earths atmosphere...This is driving me nuts, help me physics!
