Teorema de Liouville

Liouville's Theorem states that in certain idealized systems, such as an isolated and conservative physical system, the total "spread" or "volume" of points representing all possible states remains constant over time. Think of it like a fixed-sized traffic jam: even if cars change positions, the overall number and density of cars stay the same. In physics, this means the distribution of particles in phase space (positions and momenta) doesn't compress or expand as the system evolves, highlighting the conservation laws underlying classical mechanics.
