If there was a universe without any mass, could the vacuum inside it have energy?

Photons have energy, but no mass.

I think it would be plausible for pure energy to exist without any mass. Mass is created from energy (think e = mc^2). Once that energy has been converted from mass, it can exist forever (which usually doesn't happen given that we live in a universe where mass exists and thus it usually absorbs and converts energy into something else).

I think the only way for that to happen would be for electromagnetic waves to be propagating through the vacuum. I'm hard put to think of how this could come about. Of course, if it had no mass, it could also have its own laws of physics. The rest is up to your imagination.

Energy is neither created nor destroyed, but it can change to one form to another............
the total amount of energy in the universe always remain constant.......
just follow this law of thermodynamics,,,,, u will get the answer,,,,, well energy will remain constant,,,,,,,, it will never end
