The original tower experiment to disprove that matter and antimatter are gravitationally repulsive.The concept of this experiment is flawed. It was assumed that as the photons fell down the tower they would gain gravitational energy and be blue shifted. What the logic does not take into account is that, as in the above experiments, the energy gained by falling within a gravitational field is the same as the energy lost due to gravitational time dilation. Overall, there is no energy gain. Therefore, the experiment proves nothing.
Something else occurred to me: what about Hawkin radiation? If antimatter graviticly repelled matter, wouldn't we expect black holes to emit more antimatter than matter in the form of Hawkin radiation? Could this be predicted / observed? Eeh, hope I'm not missing something obvious.
