Document Summary
The warping of spacetime by a mass will cause the direction of a light beam to change. So gravity can change the path of a light beam: Solar eclipse of 1919: 1st experimental proof for einstein"s theory of general relativity, by sir. Experimental process: how solar eclipse of may 1919 verified einstein"stheory of general. Relativity took an image (photograph) of the sky (in jan/feb 1919, when same stars were visible in the night sky -in constellation taurus) know actual positions of the stars during eclipse: moon blocks sun. Will be able to see stars in constellation taurus. Eddington found that the stars" positions had shifted, by an amount exactly predicted by. We know mercury has an elliptical orbit the orientation of mercury"s elliptical orbit drifts slightly each orbit, at a specific angular rate this drift in orientation called the advance of the perihelion of mercury. Measured in fractions of a degree (arcseconds) per century.
