How disorderly is the universe?
Entropy – disorder – increases with time, according to the second law of thermodynamics. When it maxes out, the temperature will be the same everywhere across the universe. This will happen when stars and galactic cores stop producing energy and are so far apart that they do not interact. This heat death of the universe is a suggested ultimate fate of the universe in which the universe has diminished to a state of no thermodynamic free energy and therefore can no longer sustain processes that consume energy, including life. The current entropy of the universe could tell us how far it is from this ‘heat death.’
