And light curves twice as much as one can expect by combining Newtonian gravity with special relativity. This was confirmed by Eddington during 1919 eclipse provided solid evidence for fresh off the press general relativity. This was picked up by press and made Einstein famous with general public.

One cool fact about it that’s often overlooked is that the Newtonian gravity comes mostly from curvature of time rather than space. Time ticks slower closer to the sun, and most of everyday objects travel mostly through time thus curving towards it. With the exception of light.
