There is no loss occurring at all. The energy is just changing from being highly ordered (matter) into it highly disordered ("normal" energy). So, you disintegrate a cube of wood...no more cube. But the energy which makes up that cube is still present. If you were to reconstitute the cube, the energy would also still be there, just back in the form of the cube.

Where a slight dilemma comes in for me, is that prior to the BB, 'nothing' existed. However, it seems that energy may have existed either in something like a Higgs field, or in the form of something that was symmetric which got broken. Even Branes contain lotsa energy. When they touch, we end up with a BB !
JJJ;
Matter can arise from nothing. The laws of thermodynamics actually predict it !
