[quote:BoatyMcBoatFace:MV8zNTQ0NDkzXzYzMzg1MjgwXzU3OUVFOUIw] [quote:Anonymous Coward 59686777:MV8zNTQ0NDkzXzYzMzg1MjE3XzE4MzhDNzVB] 1 electron carries 1 negative charge if we smash the electron into 1000000 equal pieces, each piece will carry 1/1000000 negative charge. Let's call it enertron. since enertrons carry the same negative charge, they repel each other. if we have a perfect bottle, which means no leakage, no react, like glass bottle to air. we put 1000000 enertrons into the perfect bottle, since enertrons repel each other, they put a pressure on the bottle wall. let's measure and call that pressure 1 vote. if we put 2000000 enertrons into the same bottle, the pressure on the wall should be 2 vote. now if 1 enertron is moving or vibrating, the rest all enertrons will share the force according to their distance. that is the mechanism of light/quantum. [/quote] So, basically: 1=1. Thanks for that. [/quote]
Original Message
If a star explodes, the radiation waves (X, gamma, etc.) would reach Earth at the speed of light (assume a constant "c" vakue).
But what about gravity? Gravitational waves weren't included in Einstein body of work.
Just recently, some gravitational waves were sensed, but no speed has been measured yet.
Are the gravity effects instantaneous?
