The laws of physics are models that we use to predict and describe the behaviour of the universe. These models are imperfect and are based on our observations of the world. While it is difficult to define what would constitute breaking a law of physics, there are examples of old laws that have been proven wrong and new discoveries that may break current laws. For instance, Newton's law of gravity is unable to completely describe the orbit of Mercury, and there are ongoing experiments with subatomic particles that have produced results that contradict the Standard Model of physics. Additionally, there are extreme scenarios, such as black holes, where the laws of physics break down and our understanding is limited. While it is unclear if anything can truly break the laws of physics, advancements in our understanding of the natural world and new evidence will continue to shape and refine these laws.

Quantum particles can violate classical physics but are described by quantum physics
The "laws of physics" are models that we use to predict the future behavior of the universe and to describe its past behavior. These models are imperfect and are based on our observations of the world. Classical physics, for example, can describe many aspects of nature at a macroscopic or optical microscopic scale but is insufficient for describing them at very small submicroscopic (atomic and subatomic) scales.
Quantum particles can appear to violate classical physics, but they are simply described by a different set of laws: quantum physics. Quantum mechanics arose from theories that sought to explain observations that could not be reconciled with classical physics. For example, Max Planck's solution to the black-body radiation problem and Albert Einstein's explanation of the photoelectric effect in 1905. These early attempts to understand microscopic phenomena led to the full development of quantum mechanics in the mid-1920s.
Quantum mechanics has been enormously successful in explaining the features of our universe at small scales and with discrete quantities and interactions that cannot be explained by classical methods. It is often the only theory that can reveal the individual behaviors of subatomic particles that make up all forms of matter, such as electrons, protons, neutrons, and photons.
The relationship between quantum and classical particles is complex. In certain limits, a quantum particle can behave like a classical one, as expressed by the Eherenfest theorem. Classical particles can be thought of as decoherent quantum particles, where information is copied out much faster than the timescales it takes to change. However, quantum and classical particles are governed by different principles and described by different equations. While classical particles have a local reality and always take the path of least action, quantum particles are mathematical descriptions that take every path.
While it may seem that quantum particles violate the laws of physics, they are simply governed by a different set of laws that better describe their behavior at small scales.

The laws of physics are based on our observations of the world and can't be violated
The laws of physics are based on our observations of the world and are models that help us predict the future behaviour of the universe and describe its past behaviour. These models are imperfect and are subject to change with new evidence. For example, Newton's law of gravity, which has been used for calculations for sending people to the moon, has its limitations and does not explain the orbit of Mercury. This led to the development of general relativity by Einstein, which provides a more comprehensive description of gravity.
While the laws of physics are based on our observations, it is important to note that they are not set in stone and can be updated or replaced as we gain new knowledge and understanding. The term ""law" in physics has a loose definition and can refer to observed properties of the natural world, fundamental ideas that form complex theories, or outdated concepts no longer applicable. As we gather more evidence and make new discoveries, we may need to modify or even overturn existing laws to accommodate new findings.
However, it is worth mentioning that the laws of physics, as we understand them today, have not been violated or broken. While there may be phenomena that seem to contradict our current understanding, such as the behaviour of subatomic particles or the nature of black holes, we cannot conclude that the laws have been broken. Instead, these anomalies present opportunities for further investigation and the potential development of new laws or theories that better explain these observations.
It is also important to distinguish between the "breaking" of laws on a macroscopic scale and the behaviour of quantum particles. While it may be true that certain laws can be violated at the quantum level, these are still governed by the principles of quantum physics. The laws of physics, as they apply to our everyday experiences and observations, have not been broken by humans or any other known entities.
In summary, the laws of physics are based on our observations of the world, and while they can be updated or replaced with new evidence, they have not been violated. The concept of "breaking" a law of physics may be misleading, as it implies a violation of established principles, when in fact, it could indicate the discovery of new phenomena or the need to refine our understanding.

The laws of physics are imperfect and are updated when new evidence is found
The laws of physics are not set in stone and are subject to change as new evidence comes to light. While the laws of physics are based on observations of the natural world, they are not always perfect and can be updated or replaced when new evidence is found. For example, Newton's law of gravity is incredibly useful and powerful, allowing us to calculate artillery ranges and even send people to the Moon. However, it is incomplete and cannot fully describe the orbit of Mercury. It was later updated by Einstein's theory of general relativity, which provides a more universal and accurate description of gravity, especially in extreme scenarios such as around black holes or when calculating GPS coordinates.
The definition of a "law of physics" is somewhat loose and can vary among physicists. Sometimes, it refers to observed properties of the natural world that have been consistently true over a long period. In other cases, it is associated with fundamental concepts that form the foundation of vast and intricate theories about the cosmos. The term can also be used for ideas that are no longer applicable. Despite these varying definitions, scientific knowledge, including the laws of physics, is always provisional and subject to change based on new evidence.
This evolution of knowledge is evident in the ongoing exploration of black holes and the Big Bang. There are singularities associated with these phenomena where the laws of physics break down, and we do not yet fully understand what occurs in these extreme situations. Additionally, the concept of tachyons, hypothetical particles that travel faster than light, challenges our understanding of physics. While tachyons may not exist, the idea highlights the potential for particles that move forward in time relative to particles traveling at or below the speed of light.
The discovery of unknown forces or particles that do not conform to existing laws of physics further underscores the imperfect nature of our current understanding. For instance, recent experiments with muons have revealed unexpected behavior that deviates from the predictions of the Standard Model of physics. This has led scientists to speculate about the existence of unknown particles or forces, possibly linked to dark matter or dark energy, that could reshape our understanding of the universe.
In summary, the laws of physics are not absolute and immutable. They are refined, updated, or replaced as new evidence emerges through scientific exploration and experimentation. This ongoing process of discovery and revision allows us to deepen our understanding of the natural world and the cosmos.

Newton's law of gravity is incomplete and doesn't fully describe the orbit of Mercury
The "laws of physics" are models that we use to predict and describe the behavior of the universe. These models are imperfect and are based on our observations of the world. While Newtonian mechanics and classical thermodynamics have been confirmed billions of times without any discrepancies, there are cases where these laws appear to break down. For example, Newton's law of gravity, while highly accurate in many cases, does not fully explain the orbit of Mercury. This is because Newtonian theory assumes that in a system with one star and one planet with a close orbit and no other massive bodies, the planet's orbit would remain constant. However, this does not align with the observed behavior of Mercury's orbit.
This discrepancy between Newton's law of gravity and the orbit of Mercury suggests that there are additional factors at play that are not accounted for in Newton's theory. In fact, even Einstein's theories struggle to fully explain Mercury's orbit. This indicates that our understanding of gravity and orbital mechanics may be incomplete, and there could be unknown forces or particles that influence the behavior of celestial bodies.
One recent experiment involving muons has also challenged the known rules of physics. Muons are subatomic particles that can penetrate objects, and they are created when cosmic rays penetrate Earth's atmosphere. In the experiment, physicists measured the decay of muons and the resulting movement of smaller particles. They found that the wobble of the muons did not match the predictions of the Standard Model of physics, which encompasses everything we know about particles' behavior. This discrepancy suggests the presence of unknown forces or particles that are not included in our current understanding of physics.
These examples demonstrate that while we cannot "break" the laws of physics in the traditional sense, we can discover exceptions or limitations to these laws that prompt us to refine and improve our understanding of the universe. As we continue to make observations and conduct experiments, we may uncover new phenomena that challenge our existing theories and lead to breakthroughs in our understanding of the natural world.

There are places and times, like black holes and the Big Bang, where the laws of physics break down
The "laws of physics" are models that we use to predict the future behavior of the universe and to describe its past behavior. These models are imperfect, and we know it. Thus, it does not make sense to speak of breaking the laws of physics. However, there are places and times where the laws of physics break down, such as black holes and the Big Bang.
Black holes are some of the most extreme objects in the universe, capable of tearing stars apart and bending spacetime. They appear to undermine the very laws of physics as we know them. This is known as the Black Hole Information Paradox. The problem arises from how black holes consume matter from the universe, from dust and gas clouds to whole star systems, and then emit it back out as radiation. This process, known as Hawking Radiation, results in the black hole losing mass. Essentially, the black hole is reversing entropy, which is not supposed to be possible according to the laws of physics. Entropy is a measure of how chaotic something is, and it always increases; it cannot decrease.
The concept of singularities, such as black holes and the Big Bang, is another example of where the laws of physics break down. Singularities are problematic because various quantities, such as density, become infinite, and infinity is not a physical quantity. Our current understanding of physics, including the theory of general relativity, cannot accurately describe what happens at the center of a black hole or during the initial moments of the Big Bang due to the presence of these infinities.
In the case of the Big Bang, the interaction energies and strengths are extremely high, exceeding the approximations that we typically use. This situation calls for a new theory of physics capable of handling such high-energy regimes. It is important to note that when physicists say that the "laws of physics break down," it does not imply that there is no possibility of discovering laws to describe these phenomena. Instead, it acknowledges that our current understanding of physics has not yet progressed far enough to provide satisfactory explanations.
