I know that Dark Matter and Dark Energy are 2 different animals. My question is not related to the difference between the 2. My question is, if dark matter exists, and since matter has energy, then dark matter must have energy associated with it. So while I hear a lot about Dark Energy and Dark Matter, I hear nothing about the 'Energy of Dark Matter'. Except from the Brane Theorist's possible explanation that dark matter is gravitational energy from other Universes. But if Dark Matter consists of WIMP particles, what's the energy of such a postulated particle? Would it be the same as the energy of an 'ordinary' particle, like kinetic energy, or E =mc^2 energy?
