On Einstein’s view of gravitation, the earth moves in an elliptical path around the sun, not because a force is acting on it, but because the world of space-time is so disturbed by the presence of the sun that the path of least time through space is the elliptical path observed. There is therefore no need to introduce any idea of “force” of gravitation.
The more matter is present, the more space is curved. And so it happens that the light from a star just behind the sun will come bending round it, like a train round a railway curve, and fall upon our eyes or cameras–that is, when the sun’s glare is shut out during an eclipse–and we can see or photograph the star. It will appear to be shifted from its true position–how far shifted, Einstein has worked out. At the last eclipse the stars appeared where he had predicted.
