Heat death of the universe

01The last stars will burn out in approximately 100 trillion years; after that, only stellar corpses remain for quadrillions more.
02Black hole evaporation via Hawking radiation means a stellar-mass black hole takes 10^67 years to vanish — the longest countdown in physics.
03In heat death, entropy is maximized: no information can be processed, meaning no thought, computation, or memory is physically possible anywhere.

In roughly 10^100 years, the last black hole evaporates and nothing happens again — ever. No temperature gradients, no usable energy, no events. The universe reaches perfect, permanent silence.
