Could we picture the universe without entropy (in it)?

[QUOTE="Orodruin, post: 6042383, member: 510075"] This is wrong. The point is that there are many (many!) more microstates that satisfy the half-and-half condition than the all-separated condition. It is therefore much (much!) more likely that the system will remain in its mixed state. Let’s do the counting in the case of two blue and two white particles. For the separated state there are only two possible microstate. Both blue to the left and white to the right or vice versa. For the fully mixed state there are two independent possibilities for each color: blue1 left & blue2 right or blue1 right & blue2 left - and the same for white. This leads to a total of 4 possible microstates that are all-mixed. Twice the number of the all-separated case and we only had four particles! The effect is magnified many (many!) times as you increase the number of particles. [/QUOTE]
