Universe (as a thermodynamic system)

The universe as a thermodynamic system is like a vast, interconnected energy network where energy and matter are constantly interacting. It follows principles similar to those governing engines and refrigerators, such as increasing entropy, which means systems tend to move toward disorder. Over time, energy disperses more evenly, leading to a gradual cooling and the eventual "heat death" of the universe. In this view, the universe's evolution involves transformations and exchanges of energy, governed by physical laws, shaping the large-scale structure and dynamics we observe today.
