What are the 3 confirmations of Einstein's general theory of relativity?

Question

I need to know this for a physics exam.

Answer 1

E=mc^2 is Special Relativity, not General. General is about gravity. There are more than three. Precession of Mercury's obit, deflection of Starlight, Gravitational time dilation of satellites, gravitation red-shift of gamma ray energy as measured by Mossbauer Spectroscopy, and decay of pulsar rotation speed come to mind. You'll need to read the book to find out which ones teach' expects to see to avoid being marked "wrong". That's just way it seems to be.
