Thinking of entropy as a measure of disorder, how do we distinguish order and disorder. Entropy should increase with time resulting in more and more disorder with the passage of time. The solar system evolved with time. Now, do we consider the formation of the solar system as getting ordered or disordered? If I have not misconceived it, the same question should also be relevant to formation of stars, galaxies as well as to formation of life on earth (through abiogenesis), all of which take/took huge amounts of time to be formed. So are these formations a result of getting ordered or disordered?
