When I read thermodynamics in my college coursebook since then I had got a new idea to explain the ultimate fate of universe according to Second Law of Thermodynamics. According to second law of thermodynamics "the entropy(measure of disorder) of a closed system is always increasing and reaches the maximum thenafter a state of equilibrium is reached then entropy of such system doesn't change anymore". So univetse can also be considered as a closed system and self contained like a upside black hole according to Dr. Hawking's work. So the entropy of the universe is increaing now. All the phenomenon that are going in the universe like formation of stars, death of stars, evolution of we like creatures, collisin of galaxies etc. increases the entropy of the universe and finally from billions of years from now a state of equlibirium is reached. In such a condition each point in the space will have same temperature and pressure so that no further evolution occurs. How is my idea. Please someone suggest me how can i prove it mathematically by using the laws of physics?
