Quick Summary

The "big chill" is a hypothetical scenario for the ultimate fate of the universe, also known as heat death. This occurs if the universe continues to expand indefinitely, leading to a decrease in density. Old stars would burn out, and new star formation would cease, resulting in a cold, dark universe with maximum entropy and no available energy. This scenario is a possible outcome of the big bang model, particularly if dark energy acts as a cosmological constant.1
