Experiment This Weekend To Measure Speed Of Gravity
An anonymous reader writes: "Is gravity an instantaneous phenomenon, as we were taught in high school, or is its speed, like all other Einsteinian phenomena, bounded by the speed of light? A radical new experiment, proposed by Sergei Kopeikin, and involving the Very Long Baseline Array, is set to occur this weekend, and results should be known within about two weeks."
I'm not sure about the speed of gravity (the force reponsible for attraction between two bodies) but I've noticed that the speed of anti-gravity (the force responsible for repulsion between two bodies) is roughly the speed of light. Everytime I see some hot babe in a bar and start walking towards her, she turns and runs away in the opposite direction when she sees me coming.
If independent verifcation of this experimental result is needed, I can get my buddies (who always guffaw when this happens) to pledge that these results are repeatble!
