SUMMARY

This discussion focuses on calculating varying energy within a Schwarzschild metric for a non-rotating spherical mass distribution. The integration of energy is presented through a specific mathematical formulation involving the constants G (gravitational constant), M (mass), and r_s (Schwarzschild radius). The derived equations are dimensionally consistent and provide insights into energy changes in spacetime metrics, particularly in relation to radiating bodies. The discussion references Loyd Motz's paper on gravitational generation of electromagnetic radiation as a source of inspiration.

The Energy changing in a Schwartzschild Metric

It is not obvious how to integrate an energy in the Schwartzschild metric unless you derive it correctly. The way this following metric will be presented will be:

\int_{t}^{t'} c^2 d\tau^2 dt = \int_{t}^{t'} (1 - 2\frac{Gm}{\Delta E} \frac{M}{r_s} c^2 dt^{2}) - \frac{dt}{(1-2\frac{Gm}{\Delta E} \frac{M}{r_s})} - r^2 d \phi dt

This will be interpeted as

\int_{t}^{t'} c^2 d\tau^2 dt = \int_{t}^{t'} (1 - 2\frac{Gm}{E - E'} \frac{M}{r_s} c^2 dt^{2}) - \frac{dt}{(1-2\frac{Gm}{E - E'} \frac{M}{r_s})} - r^2 d \phi dt

And this metric is dimensionally-consistent to calculate the energy changes within a metric. Usually, in the spacetime metric, we treat it as a energy efficient fabric. This can be a way to treat a metric with a type of energy variation consistent perhaps with a radiating body.

I was inspired to find a more simple example of a varying energy from Loyd Motz' paperA Gravity Generation of Electromagntic Radiation and the Luminosity of QuasarsI can't link
 
Sorry.. was in a rush when I wrote this, I forgot my dummy variables, inserted now.
