Well I relate more to your example of the balloon than all that other stuff as I'm not a physicist, however as you describe gravity in such a way, which is a clear contradiction of high school physics (name a force...gravity), then I'll ask you to explain the demonstration of atomic clocks being affected by gravity. The clock in the aeroplane being flown at high altitude being found to be at a different setting to that kept on the ground...

Does this also mean incidentally that the lifespan of the Mars Rovers that is being quoted as 3 months is in fact wrong because time does not move at the same rate on the surface of Mars?
