And that gravity is not a force, but the curvature of space and time.

I believe that the energy-momentum tensor describes the distribution of mass in spacetime.

And through Einstein’s equation it reveals to me the metric tensor.

I believe that the metric tensor expresses the curvature of spacetime.

And through it I can create the connection symbol.

I believe that the connection symbol adjusts for the changing basis vectors in curved space.

And allows me to define the covariant derivative.

Using the covariant derivative I can create the geodesic equation.
