First, please tell me if following logic and assumptions are correct. The 4 forces of the universe generate all the changes in velocity of particles in the universe. The particles in the universe behave in such a way that entropy increases over time. Therefore, the 4 forces of the universe increase entropy.
But that raises the following questions for me. Had electromagnetism attracted like charges and repelled opposite charges, would the entropy of the universe decrease over time? Had gravity repelled objects of mass instead of attracting them, would entropy decrease over time?
If this is indeed the case that the opposite of the forces would decrease entropy, why would it so happen that every force happens to increase entropy? Is the increase in entropy itself the fundamental aspect of the universe and the forces fall in line with that or is something more subtle going on?
