Amelia asked the Naked Scientists:I deduced that it is not so much the weight of air pushing on all directions that hold the board up against the glass of water, but rather, the sum total of gravity pulling from other celestial bodies.
there are two main theories about the attraction of gravity one is that it is mediated by virtual particles in a similar manner to the electro magnetic force and the other that the presence of mass distorts space time so that objects take a different path thru it.
