In thermodynamics (a branch of physics), entropy is a measure of the unavailability of a system’s energy to do work. And according to a law - Entropy is always increasing.... we are all witnessing such a 'real life' system where all human energy is being wasted in trivial pursuits and the 'Real' energy for good work is invisible. Going by the stated LAW of nature, well... doomsday isnt far off...... how far??? that is the BIG question.
