In astrophysics, entropy is a concept that describes the degree of disorder or randomness in a system, and it is rooted in the second law of thermodynamics. In general terms, entropy serves as a measure of the unavailable energy in a system to do work and is indicative of the system's tendency to evolve towards thermodynamic equilibrium.
