I've read somewhere that gravity travels at the speed of light.
Has this been measured? If so doesnt anyone find it bizarre?
If so it would mean if a the sun vanished (and all its mass) it would still have a gravitational effect until minutes later when the abscence-of-gravity wave would reach a planet (and it would straighten it path towards the exterior of the solar system), right?
Are there Doppler effects of effects related to massive objects that are traveling fast?
If gravity propagates, and can alter the trajectory of light, why cant gravity not alter the trajectory gravity?
Does one feel more gravity when a planet is between himself and the sun(beyond the planet+sun), meaning that sum of the gravity-ishess travelling on either side of the mid body gets curved and reaches you? (I guess not otherwise black wholes would have so much gravity that even gravity would not escape )
