    The universe as we know it appears to have three major components - ordinary matter (including e-m energy), dark matter, and dark energy. Current theory has the first two as constant. However so little is known of dark energy, no one can really answer - one idea is that it is proportional to the volume of the universe, so that it increases as the universe expands.

    How about entropy? The useful energy don't reduce?
