I learned about entropy is chemistry, can someone please explain how this term is used in physics? Thanks.

Entropy is a measure of the disorder or randomness in a system. In the universe, entropy is constantly increasing due to the second law of thermodynamics, which states that the total entropy of a closed system will always increase over time. This means that the universe is moving towards a state of maximum disorder and randomness.
The concept of entropy is closely linked to the beginning of the universe. According to the Big Bang theory, the universe started as an incredibly hot and dense state, with very low entropy. As the universe expanded and cooled, entropy increased, leading to the diverse and complex structures we see today.
Entropy plays a crucial role in the formation of stars and galaxies. As gas and dust particles in the early universe clumped together due to gravitational forces, they released energy and increased in entropy. This process eventually led to the formation of stars and galaxies, which continue to evolve and increase in entropy over time.
Entropy is closely linked to the fate of the universe. As the universe continues to expand and increase in entropy, it will eventually reach a state of maximum disorder, also known as the heat death of the universe. This is when all energy is evenly distributed and no work can be done, resulting in a static and lifeless universe.
While it may be possible to locally decrease entropy, such as in living organisms that maintain internal order, the overall trend is towards increasing entropy. According to current theories, it is not possible to reverse or decrease entropy on a universal scale. However, this is still an area of ongoing research and debate in the scientific community.
