Entropy - the “ clock ” of the universe Entropy is a measure of disorder. Low Entropy - high order, High Entropy - high disorder. Entropy is a measure of disorder. Low Entropy - high order, High Entropy - high disorder. The total entropy of the Universe, which is an isolated system, is always increasing. The total entropy of the Universe, which is an isolated system, is always increasing. The total entropy tend towards a maximum, corresponding to complete disorder. Simultaneously, the available energy of the Universe tends towards a minimum. The total entropy tend towards a maximum, corresponding to complete disorder. Simultaneously, the available energy of the Universe tends towards a minimum. This means that a time must finally come that no energy being available for us - “the heat death of our Universe.” This means that a time must finally come that no energy being available for us - “the heat death of our Universe.” “The three ages and death” by Hans Baldung Grien, simulates the above. “The three ages and death” by Hans Baldung Grien, simulates the above.
