That's what I thought as well. This would seem to contradict Mr. Lawrence's previous conjecture that time within a hollowed out sphere positioned at the center of a planet would experience time more slowly than time experienced near the surface of a planet. Since the effects of gravity (i.e. acceleration) would essentially be null at the center of any planet, wouldn't time speed up relative to time being experienced at the surface? What am I missing here? Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
