Question

Quizplus · Accepted Answer

The heat death of the universe is the theoretical scenario in which the universe reaches a state of maximum entropy in which all matter is evenly distributed and there are no more temperature gradients or energy sources to power any kind of work or force. This means that the universe would eventually become cold, dark, and unable to sustain life or any kind of activity. This is due to the second law of thermodynamics, which states that over time, any isolated system will tend to disorder and entropy.
