It seems to me that it would be extremely shocking if antimatter fell up. Having a bit of antimatter in an elevator, one could then tell, without looking out, whether the elevator was stationary in a gravitational field, or accelerating in the absence of an external field -- in contradiction with general relativity, which says they have to look the same. |
