Once entropy reaches its maximum, theoretical physicists believe that heat in the system will be distributed evenly. This means there would be no more room for usable energy, or heat, to exist and the Universe would die from 'heat death'. Put simply, mechanical motion within the Universe will cease.
Will the universe end in entropy?
Entropy would continue to increase as well: Star formation itself will end in 100 trillion years as all the matter to fuel them is exhausted. Black holes will evaporate, matter itself will eventually decay into radiation and the universe will be a cold, lightless, lifeless place for the rest of eternity.
Does the universe prefer entropy?
Put simply, entropy is a measure of disorder, and the Second Law of Thermodynamics states that all closed systems tend to maximize entropy. ... Overall, the entropy of the universe always increases. Entropy also manifests in another way: There is no perfect transfer of energy.
