Universe's Entropy

Entropy is a measure of disorder or randomness in a system. In the universe, entropy tends to increase over time, meaning processes become more disordered. For example, when stars burn fuel, energy disperses and systems become less organized. The universe started in a highly ordered state after the Big Bang and has become more disordered since then. This increase in entropy is associated with the arrow of time, indicating that time moves forward as the universe evolves towards greater disorder. Understanding entropy helps explain why certain processes happen spontaneously and how the universe's complexity changes over time.
