Ok, imagine a fixed volume that could contain various forms of energy.
IE, a cloud of photons, a cloud of electrons, a cloud of protons, or a cloud of neutronium.

Also, imagine that the value of energy is the same in each case.

This may sound like a dumb question, but do we know if the total amount of energy within the volume will bend spactime the same way regardless of the form it takes?
