Einstein was correct in his speculation that the speed of gravity equals the speed of light. Einstein speculated this but until now no one had been able to test it. Two scientists have recently "measured the amount that light from a distant star was deflected by the gravity of Jupiter as the planet passed in front of the star." This was done by Edward Fomalout, of the US National Radio Astronomy Observatory and Sergei Kopeikin, of the University of Missouri. This is a very important find for physics. Light is therefore basically not restricted except for the space time curvature, which in effect is gravity (to greatly oversimply using my limited understanding).
