The heat Death of the Universe is one of the consequences of the Second Law of Thermodynamics that states that the heat in the universe must eventually spread out. Life on Earth is possible because the Sun provides Earth's surfaces. The Earth also holds a vast reservoir of internal heat. The "heat-death" of the universe is when the universe has reached a state of maximum entropy. This happens when all available energy has moved to places of less energy. Once this has happened, no more work can be extracted from the universe. Since heat ceases to flow, no more work can be acquired from heat transfer. This same kind of equilibrium state will also happen with all other forms of energy. Since no more work can be extracted from the universe at that point, it is effectively dead, especially for the purposes of humankind. In the 1890's people began to realize that the heat in the Earth is still radiating out into the coldness of space and the Sun's energy is radiating out into the coldness of space. Eventually, billions of years down the road that heat energy is going to disperse and distribute evenly. The fate of the universe, therefore, must be for the heat to spread out uniformly, as in the second law. No energy transfer would be possible, as all the energy is taken up in matter at the exact same temperature. People experience time as one of the major variables in their lives. They try to deduce historical variables in their lives. They try to deduce historical aspects of things and time becomes an important parameter in those kinds of discussions. Time is considered an intangible physical quantity. However, what is the nature of this quantity, time? The second law of thermodynamics gives some tantalizing insights. Take the instance of a movie being played backwards. Many scenes are going to appear perfectly normal, but some forms of the motion would look very strange. For example, people diving out of a swimming pool, unbreaking an egg, unshooting an arrow, and so on. It all ties with this tendency of entropy to increase. The tendency of entropy to increase rather than decrease defines the arrow of time. It defines the direction in which time moves in people's everyday experience. Only the second law of thermodynamics incorporates this arrow of time. Somehow, the second law defines the direction of time. Whether that is a cause or effect, or whether people are merely describing some aspect of the natural word, scientists who think about energy also think about

The second law of thermodynamics states that any isolated system's entropy always increases. The heat death of the universe is a theory on the final fate of the universe, which suggests that the universe would evolve to a state of no thermodynamic free energy and therefore be unable to sustain the process that increases entropy. The heat-death of the universe is when the universe has reached a state of maximum entropy. This happens when all available energy from a hot source has moved to a colder source. Once this has happened, no more work can be extracted from the universe. Since heat ceases to flow, no more work can be acquired from heat transfer. This same kind of equilibrium state will also happen with all other forms of energy (mechanical, electrical, etc.). Since no more work can be extracted from the universe at that point, it is effectively dead, especially for the purposes of humankind.
