The laws of thermodynamics are key insights of former physicists that changed our perspective on thermodynamics. There are four laws of thermodynamics. The first law of thermodynamics states that heat is energy. The second law of thermodynamics is safe, according to one source, despite a new device that appears to break this rule. Another source suggests that breaking the original form of the second law might be possible by assuming that heat is the exchange of some kind of liquid. The 0th law states that there exists something like temperature, and it behaves like temperature. If this law were broken, we would live in a universe where temperature and hence thermodynamics does not exist.
| Characteristics | Values |
|---|---|
| 0th Law of Thermodynamics | There exists something like temperature, and it behaves like temperature |
| 1st Law of Thermodynamics | The law of energy conservation for thermodynamic processes |
| 2nd Law of Thermodynamics | Heat engines would work, temperature would couple to the electromagnetic radiation, and temperature would couple to phase changes in materials |

Breaking the second law of thermodynamics
It's worth noting that a device has been created that only 'appears' to break the second law of thermodynamics. However, the law remains intact.
The second law of thermodynamics is a fundamental rule of physics, and breaking it would have far-reaching consequences. While it might be possible to find loopholes or workarounds, the law itself is a cornerstone of our understanding of the universe and would be extremely difficult to break.

Breaking the first law of thermodynamics
Dark energy breaks the first law of thermodynamics. As the universe expands and more space is created, more vacuum energy bubbles up from nowhere.
The first law of thermodynamics states that heat is energy. However, this is often assumed, and the law is instead introduced as the law of energy conservation for thermodynamic processes.
If the first law of thermodynamics were broken, the universe would be indicted and tried by empirical observations.
To break the first law of thermodynamics, one would need to create a situation in which heat is not energy. This could be done by assuming that heat is the exchange of some kind of "liquid", as some 18th-century physicists used to do. However, this would have dramatic consequences, including:
- Heat engines, including steam engines, nuclear power plants, and refrigerators, would not work.
- Temperature would no longer couple to the electromagnetic radiation, meaning that fire would no longer exist or be warm, and neither would the sun.
- Temperature would no longer couple to phase changes in materials.

Breaking the 0th law of thermodynamics
The 0th law of thermodynamics states that there exists something like temperature, and it behaves like temperature. If this law were broken, then we would live in a universe where temperature and hence thermodynamics does not exist. This would mean that heat engines would not work, including all steam engines, nuclear power plants and refrigerators. Temperature would no longer couple to the electromagnetic radiation, meaning that fire would no longer exist or be warm, and neither would the sun. Temperature would also no longer couple to phase changes in materials.
To break the 0th law of thermodynamics, one would need to find a way to prevent the existence of temperature. This could potentially be achieved by disrupting the fundamental laws of physics that govern the behaviour of matter and energy. However, it is important to note that the laws of thermodynamics are based on empirical observations and are considered fundamental principles in physics, so breaking them may not be possible without completely reshaping our understanding of the universe.

Dark energy and the first law of thermodynamics
Dark energy breaks the first law of thermodynamics. As the universe expands and more space is created, more vacuum energy bubbles up from nowhere. The first law of thermodynamics historically corresponds to the insight that heat is energy. However, in contemporary literature, it is often introduced as the law of energy conservation for thermodynamic processes.
The second law of thermodynamics is safe and cannot be broken. A new device only 'appears' to break this fundamental rule of physics. However, breaking the original form of the second law of thermodynamics might be possible more reasonably. All we need to do is assume that heat is the exchange of some kind of "liquid", as some physicists in the 18th century actually used to do.
If the second law of thermodynamics were broken, we would see dramatic consequences:
- Heat engines would not work. This includes all steam engines, nuclear power plants and refrigerators.
- Temperature would no longer couple to the electromagnetic radiation. Fire would no longer exist or at least be warm and neither would be the sun.
- Temperature would no longer couple to phase changes in materials.
The 0th law of thermodynamics simply states: "There exists something like temperature, and it behaves like temperature". If that law is broken, then we live in a universe where temperature and hence thermodynamics does not exist.

The second law of thermodynamics is bent but not broken
The second law of thermodynamics is safe, despite appearances to the contrary. It might be possible to break the original form of the second law of thermodynamics by assuming that heat is the exchange of some kind of "liquid", as some 18th-century physicists did. However, this would have dramatic consequences, including the fact that heat engines, including steam engines, nuclear power plants and refrigerators, would not work.
Temperature would no longer couple to the electromagnetic radiation, meaning that fire would no longer exist or be warm, and neither would the sun. Temperature would also no longer couple to phase changes in materials.
However, the second law of thermodynamics is not broken by a new device that only 'appears' to break this fundamental rule of physics.
