The heat death of the universe also known as the big chill or big freeze is a conjecture on the ultimate fate of the universe which suggests the universe would evolve to a state of no thermodynamic free energy and would therefore be unable to sustain processes that increase entropy heat death does not imply any particular absolute temperature.

Heat death of the universe reddit. It only requires that temperature differences. Most people theorize that the entire universe will end one day in a heat death or something else as a result of entropy. Nothing has energy to gain or lose compared to anything else.
