This is Einstein's General Theory of Relatitivity = gravitation. Since both the left and right sides of the equation are symmetric under interchange of indices ...

The equivalence principle is the statement that all bodies fall the same way in a gravitational field. This fact was well known to Galileo and he (supposedly).
Bergman (1968), for example, says that “This (equivalence) principle cannot be eliminated without destroying the theory (of general relativity) as a whole.”.
In that local inertial frame, all the laws of physics are the same as they are in special relativity. (electrodynamic, hydrodynamic, strong+weak nuclear, ...)!! ...
Figure 3: Gravitational dilation example. As an example, let Bob be on the Earth and Alice fly off into space. Each measures a time (τA or τB).
Two different forms of time dilation, namely, the kinematical time di- lation of special relativity and gravitational red shift are coupled together.
Space-time curvature effects local structure of light cone, and the behaviour of null geodesics. Since gedanken experiments of Special Theory of relativity (STR) ...
And time passes more slowly for someone in a stronger gravitational field than it does for someone in a weaker gravitational field.
Note. Einstein proposed that gravity is not a force, but a curvature of spacetime! He hypothesized that free particles (and photons) follow ...
I began this paper by criticizing the 'conventional wisdom' that the relativity and equivalence principles apply to general relativity because ...
