Einstein first published equations in 1915 with three predictions:
|
2 |
Bending of Light as it passed massive objects such as stars
-
Experimentally verified in 1919 by observation of star field near the sun during an eclipse
|
3 |
There is a small (43 seconds of arc per century -- with 3600 seconds of arc as one degree) shift in Mercury's perihelion not accounted for by Newtonian Gravity
-
Einstein verified that General relativity predicted this soon after publication of equations
|
4 |
"Blue" shift (frequency or energy change) of light as it falls down a gravitational field
-
In 1960, (5 years after Einstein's death) Pound and Rebka observed the two parts in 1012 frequency shift as photons fell 74 feet of the Jefferson tower of the physics building at Harvard
-
They used Mossbauer effect
