The heat death of the universe seems to be a logical consequence of the Second Law of Thermodynamics. Look for information about this theory and refute or support it

The Heat Death Theory relates to thermodynamics. It was formulated in 1862 by Lord Kelvin, Hermann von Helmholtz, and William John Macquorn Rankine. It states that over time, heat will transfer from warmer to cooler objects and will eventually lead to a drop in temperatures everywhere. Temperatures will continue to drop until everything is equal, in which case, life would cease to exist.
According to Freeman Dyson, gravity will prevent the heat death from ever occurring. Dyson relates the heat death to what he calls the cooking rule. “Generally, the rule says that any object gets warmer when it gains energy, and gets cooler when it loses energy” (Dyson 2011). Like a steak on a grill. If this were tr
ue all of the time, then the heat death theory could be considered true. But, this is not true for objects of astronomical size because gravitation is the main source of energy. Dyson uses the sun as an example. “As the sun loses energy by radiation, it becomes hotter and not cooler. Since the sun is made of compressible gas squeezed by its own gravitation, loss of energy causes it to become smaller and denser, and the compression causes it to become hotter” (Dyson 2011). Normally, as heat transfers from a hot object to a cool object, the hot object loses energy, or heat. Astronomically large objects, like the sun, are dominated by gravitation so as a hot object transfers heat to a cooler object, it gets hotter. According to this, the heat death theory is impossible because temperature in the universe continues to increase. “Gravitation gives us a universe hospitable to life” (Dyson 2011).
