Ianahep, but maybe work backwards from gravity vs spacetime equations? I'm assuming gravity is the exchange mechanism that drives this, so if you needed x gravitational field to produce y displacement, then given y displacement you have some energy equivalent of x in mass?

A starting point is "stress-energy tensor" as a keyword to search.
