I don't expect anyone to get this, but it's worth a shot. Maybe someone will impress me. Mathematically relate Planck's Quantum mechanical equation and Einstein's equation of the law of conservation of energy to the heat death of the universe (Remember that the head death of the universe implies that all mass is eventually converted to energy-aka-burning up. In other words, use the 2nd law of thermodynamics). I know all of the equations, but I'm clueless on how to relate them. Please help!
