>Contrary to popular opinion, uniformly distributed matter is unstable when interactions are dominated by gravity (Jeans instability) and is actually the least likely state, thus with very low entropy. Most probable states, with high-entropy, are those where matter is all lumped together in massive objects.

That means over time the system becomes more ordered and starts organizing itself into spheres.

I once brought this question up on physics stack exchange and basically the answers were either some form of rolling their eyes at me or dismissing me outright. The people who did answer the question stated that as particles organize themselves into spheres some other part of the universe gets hotter as a result and that the seemingly self organization I see going on with the solar system was just an isolated system.

This answer still seemed far fetched to me. It still looks as if some overall self organization is still going on if the universe gets hotter on one side and matter gets organized into solar systems on another side.

It took me 3 years to somewhat understand what entropy is. If you have loaded dice that always roll 6s then the dice rolling ALL 6s is the highest entropic state. rolling Random numbers would then be a low entropy state.

Entropy is simply a phenomenon of probability. As time moves forward, particles enter high probability configurations. Like rolling dice. As you roll dice more and more... rolling random numbers has a higher probability then rolling all 6s...

It just so happens that disordered arrangements happen to have higher probabilities in most systems. But if you look at a system of loaded dice or the solar system... in those cases Ordered configurations have higher probabilities. That's really all it is. The entire phenomenon of entropy comes down to probability and the root of probability is the law of large numbers.
