Eddington found that the star had indeed shifted position, and by the exact amount predicted by the equations of General Relativity. This apparent shift of a star's light as it passed close to the sun on its way toward us was the first physical evidence in support of Einstein's General Relativity. And Mankind's basic understanding of light, matter, and time changed forever.

Since Eddington, every experiment to test Einstein's theory of General Relativity has confirmed it. Not a single experiment to this day has cast the smallest doubt on the unity of matter and space-time. And in science, that's saying a lot, because the very nature of scientific endeavor is to challenge the models we have. We are always trying to disprove Relativity, to look for a flaw, an inconsistency, but none has yet been found. It turns out that the universe is more connected, strange and beautiful than our limited human senses can show us directly.
