I have been recently wondering about black holes and the laws of thermodynamics. So I would like to ask: Can there be physical movement without thermal radiation in other words loss of energy in thermal form? Every particle in the universe that have mass will be in movement. I am in belief that black holes/singularity is not stationary objects so if they are in movement they should be radiating heat? If there is no particle without mass then there are no stationary particles in the universe? Hawking radiation equals thermal radiation and radiated energy from the black hole in this case? That would mean: E=mc2+Hawking radiation then? I bet this have been discussed earlier so if you can point me a link to an answer i will look there... Thanks!
