  Also known as the heat death of the universe, it’s the natural progression of the second law of thermodynamics — a state of maximum entropy where all mechanical energy has been converted to heat that can’t be used for work.

  As Tora highlights, this basically describes the natural outcome of the Second Law of Thermodynamics, according to which the entropy of the universe will keep increasing. As it does so things will tend toward thermal equilibrium in which temperature will be uniform and energy is dispersed among many tiny modes of motion, rather than concentrated in a few larger-scale modes such as now. It is basically the predicted death of the Universe.
