The laws of physics are models that describe and predict the behaviour of the universe. These models are based on our observations of the world and are constantly evolving as we learn more about the universe. While the laws of physics are fundamental to our understanding of the natural world, they are not absolute and can be broken or violated under certain conditions. For example, new experiments have revealed unknown forces that affect the behaviour of subatomic particles, challenging our existing understanding of physics. Additionally, there are extreme scenarios, such as black holes or the Big Bang, where the laws of physics as we know them break down, and we have yet to fully understand the underlying principles at play.

The laws of physics are models to predict future behaviour
The "laws of physics" are models that aim to predict the future behaviour of the universe and describe its past behaviour. These models are based on observations of the world and how things in the universe act physically. While they are essential tools for understanding the universe, it is important to acknowledge that they are imperfect and subject to change as new evidence emerges.
The laws of physics, as we know them, are constantly evolving as we make new discoveries and gain a more intricate understanding of the universe. For example, Newton's law of gravity, which has been incredibly useful for calculations such as artillery ranges and even sending people to the moon, has been found to have limitations. In certain scenarios, like the orbit of Mercury or the extreme conditions around a black hole, Newton's law breaks down, and we need to turn to more advanced theories like Einstein's general relativity to explain these phenomena accurately.
The concept of "breaking" the laws of physics is a complex one. On one hand, the laws of physics are based on our observations of the natural world, and as such, they can always be updated or modified in the face of new evidence. In this sense, the laws are more like guidelines or models that are constantly refined and improved upon. This is exemplified by the discovery of quantum mechanics, which revealed that certain behaviours of quantum particles could not be explained by classical physics, leading to the development of a new branch of physics that successfully described these phenomena.
However, it is essential to distinguish between "breaking" the laws of physics in the sense of discovering new phenomena that require an updated model and the idea of defying or violating the fundamental principles that govern the universe. While it may be possible to find exceptions or limitations to certain laws, the underlying principles of physics, such as the conservation of energy, are believed to be universal and unbreakable. No human or quantum particle can defy these laws because they are intrinsic to the very fabric of the universe and our understanding of it.
While the laws of physics are indeed models that can be refined and improved, they provide a foundation for our understanding of the universe and the behaviour of matter and energy within it. These laws, as we discover and refine them, allow us to make predictions about the future and interpret the past, guiding our exploration and discovery of the cosmos.

Quantum particles can violate classical physics laws
The laws of physics are models used to predict and describe the behaviour of the universe. These models are imperfect and are based on human observation of the world. While physics does not have "laws" per se, it has overlapping mathematical models and frameworks. These are called "theories".
Quantum particles do not violate the laws of physics; they are, in fact, perfectly described by quantum physics. However, they may violate classical physics laws. For example, in classical mechanics, the initial energy of a system can be checked, and when measured again after an evolution, the energy will remain constant. In quantum mechanics, however, a particle is described by a wave function, and its energy is proportional to its frequency. When a wave function is a combination of multiple sine waves, the particle is in a "superposition" of energies. When its energy is measured, the wave function seems to "collapse" to one of the energies in the superposition. This is known as superoscillation.
Superoscillation does not contradict any laws of physics, but when applied to quantum mechanics, it can lead to a paradox. In a thought experiment, Aharonov, Popescu, and Rohrlich exposed this paradox. They suggested that energy conservation could be violated in individual instances, which many physicists disagree with.
Additionally, an experiment with muons has revealed behaviour that does not align with the Standard Model of physics. The muons' wobble, or precession, did not match the expected calculations, indicating the potential involvement of unknown particles or forces not included in the Standard Model. This finding suggests that there may be aspects of the universe that are not accounted for by the existing rules of physics.
While quantum particles can exhibit behaviour that seems to violate classical physics laws, they are still subject to the laws and theories of quantum physics, which provide a more accurate description of their behaviour.

Laws of physics are based on observations of the world
The laws of physics are models that help us predict the future behaviour of the universe and describe its past behaviour. They are based on empirical observations of the world around us and how it works. These observations are then translated into mathematical models, which we call laws.
The process of formulating these laws begins with observations of reality, which are then translated into mathematical equations. When the maths is simple and elegant, these equations are called laws. For example, the laws of physics once stated that the Earth was the centre of the universe, and later, that the Sun was the centre of the universe. We now know that both these conclusions are wrong.
The laws of physics are also based on scientific observations and experiments, which are repeated under different conditions to reach inferences that can be accepted worldwide. These laws are continuously validated by the scientific community over time. Classical physics, for instance, deals with the observable universe around us, while atomic physics deals with subatomic particles and their interactions (quantum mechanics).
While the laws of physics are based on observations, they are imperfect models. For example, a recent experiment with muons has produced results that do not match the expectations of the Standard Model of physics. This has led to speculation about the existence of unknown particles or forces and the possibility that the rules of physics are inadequate.
In summary, the laws of physics are based on observations of the world, translated into mathematical models, and continuously validated through experiments. However, they are imperfect and may be revised or replaced as new evidence and theories emerge.

The laws of physics can be broken in black holes
The laws of physics are models that we use to predict the future behaviour of the universe and to describe its past behaviour. These models are imperfect and are based on our observations of the world. While some laws can be violated by quantum particles, there has been no verified "breaking" of the laws of physics.
Black holes are some of the most extreme objects in the universe, capable of tearing stars apart and bending spacetime. They are surrounded by much mystery and appear to undermine the laws of physics as we know them. This is known as the Black Hole Information Paradox. The paradox arises from the way black holes consume matter from the universe, from dust and gas clouds to whole star systems, and then expel it. This process of consumption and expulsion increases the mass and size of the black hole. However, black holes also slowly lose mass through a complex quantum effect around the event horizon, which turns the mass of the black hole into homogeneous radiation known as Hawking Radiation.
The problem with this process is that it reverses entropy, which is a cornerstone of physics. Entropy is a measure of how chaotic something is and it always increases, never decreases. When black holes consume matter and then expel it, they decrease entropy, which is not possible according to the laws of physics. This paradox suggests that black holes are capable of breaking the laws of physics.
However, a new theory suggests that ordinary black holes without a central singularity may obey the laws of physics. The singularity is the most mysterious and problematic part of a black hole, where our concepts of space and time no longer make sense. If black holes do not have singularities, they become much more ordinary. This theory may somewhat demystify black holes, but it also opens up new questions that remain to be answered.

New experiments can break the rules of physics
The "laws of physics" are models that help us predict the future behaviour of the universe and describe its past behaviour. These models are imperfect and are based on our observations of the world. As such, there is no definitive answer to whether the laws of physics can be broken. However, new experiments can reveal discrepancies or exceptions to existing laws, leading to the refinement or replacement of these laws.
For example, in 2021, an experiment with muons, a type of subatomic particle, revealed unexpected behaviour. The muons' wobble, or decay, did not match the predictions of the Standard Model of physics, which encompasses everything we know about particles' behaviour. This finding suggests the presence of an unknown force or particles that are not included in the Standard Model.
This discovery highlights the provisional nature of scientific knowledge. While the laws of physics provide a framework for understanding the universe, they are subject to change as new evidence emerges. For instance, Newton's law of gravity, while powerful enough to send people to the moon, cannot completely describe the orbit of Mercury. In such cases, more advanced laws, such as Einstein's theory of general relativity, are needed to provide a more accurate description.
Furthermore, there are extreme scenarios, such as black holes and the Big Bang, where the laws of physics break down, and we do not yet have a complete understanding of what occurs. These unknowns present opportunities for new experiments and theories to expand our understanding of the universe and potentially break existing laws of physics.
While it is unclear if any being can violate the laws of physics, the concept of tachyons, hypothetical particles that travel faster than light, challenges our understanding of causality. The existence of such particles would suggest a reversal of time's arrow for these particles relative to those travelling at or below light speed.

Frequently asked questions
The laws of physics are models we use to predict the behaviour of the universe. These models are imperfect and can be improved upon. For example, Newton's law of gravity is incomplete and does not account for the orbit of Mercury. In such cases, we can "break" the law and upgrade to a more sophisticated model, such as Einstein's theory of relativity.
Quantum particles do not break the laws of physics. While they may violate classical physics, their behaviour is perfectly described and predicted by quantum physics.
In certain situations, such as black holes or the Big Bang, the laws of physics break down, and we do not know what happens. In these cases, we may need to overturn existing laws or develop new ones to explain these phenomena.
Humans cannot break the laws of physics. These laws are based on our observations of the natural world and how things in the universe act. While we can discover new phenomena or improve our understanding, we cannot directly violate these laws.
The concept of "breaking" the laws of physics implies that we have a complete understanding of the universe and have defined all the rules, which is not the case. We are constantly learning and refining our knowledge, so instead of breaking the laws, we may discover new phenomena or develop more accurate theories to explain our universe.
