According to the theory of general relativity, mass causes spacetime to curve, and spacetime tells objects how to move. If you look at t...

Start with light speed (c) squared equal to velocity (v) squared: Divide both sides of the equation by c^2: We know that g is accele...

Here is my new and improved derivation of Christoffel symbols and the covariant derivative. We begin with the metric. Let's co...

Here is one way to derive the Riemann, Ricci and Einstein tensors:

Here's one way to derive the Lorentz factor: Here's how to derive the velocity addition (and subtraction) formula: ...
