H-theorem

h-theorem is a mathematical idea about how things work in the universe. It shows a connection between how much energy is in a system and how that energy is moving around. h-theorem says that over time, the energy will spread out and become more evenly balanced. In other words, the energy in an area tends to even out. Imagine a room with two people. Over time, the energy in the room will become balanced and the two people will be just as energetic as each other. h-theorem helps us understand why this happens.
