cause of inertia of masses

[kurious]

If dark energy accounts for the inertia of masses, then there is a possible explanation for the increase of mass with increasing pressure in general relativity, and the increase in mass with increasing speed in special relativity.In a mass under pressure, the atoms move faster and so would "collide" with dark energy and perhaps compress it more than at lower atomic speeds.Compression = pressure = source of mass in general relativity.The Hawking equation for the temperature of a black hole says that the temperature depends on its mass.If its mass depends on dark energy, then we could say that a 5 solar mass black hole has a very low temperature because of dark energy.Take away dark energy - the cause of the black hole's inertia - and the temperature of the black hole would rise.
Thus some black holes could be particularly energetic because there is not much dark energy in their immediate vicinity.
