The terms law and theory are used in science to refer to statements of truth that may change with better evidence or more data. A theory explains something, while a law describes it. For example, the theory of evolution by natural selection explains how organisms adapt, while the law of conservation of mass describes a fact. Laws are not set in stone and can be overturned, as some of Newton's laws demonstrate. Theories, on the other hand, are coherent groups of tested general propositions that are commonly accepted as correct and are used to explain and predict phenomena. They can be proven or disproven through scientific methods. Scientific theories are refined and expanded as we learn more about the universe, and occasionally, new evidence is so profound that old theories are discarded entirely.

What You'll Learn

Laws are simple facts and formulas that are universally applicable
The concept of laws and their nature has been a subject of debate among scholars for centuries. While there is no universally accepted definition of a law, it is generally understood to be a set of rules and guidelines that govern behaviour and are enforced through social institutions. These rules are often based on simple observations and can be proven mathematically or through experiments. For instance, Hooke's Law states that the amount a spring stretches is proportional to the force applied, which can be written mathematically as F=-kx.
However, it is important to distinguish between different types of laws, such as natural laws and legal laws. Natural laws, such as the laws of physics, are based on scientific observations and experiments, while legal laws are the rules and guidelines that govern a society and are enforced by social institutions. These legal laws are the focus of the rule of law, which is a system that promotes accountability, justice, open government, and respect for fundamental rights, including human, property, contract, and procedural rights.
The rule of law is built on universal principles that aim to ensure that laws are clear, publicized, stable, and applied evenly. This system is traceable to ancient scholars and is found in most major legal traditions. It emphasizes the importance of community commitment and the involvement of citizens in the law-making process, which increases the legitimacy of the laws. This participation can take many forms, such as collaborating with government officials, exercising freedom of speech and association, and holding governments accountable.
While laws are meant to provide a stable framework, they are not static and can be changed or overturned. This is because laws are based on our understanding of the world, which is constantly evolving. As new evidence or perspectives emerge, laws may need to be adapted or replaced to reflect these changes. For example, some of Newton's laws are known to be inaccurate, yet they are still referred to as laws due to their historical significance and practical utility.
In conclusion, laws are indeed built upon simple facts and formulas that have universal applicability. However, the complexity arises in the interpretation and implementation of these laws within the context of society and the natural world. The dynamic nature of knowledge and the need for flexibility in governance contribute to the ongoing evolution of laws over time.

Theories are based on laws, facts, testing, and evidence
Theories and laws are two distinct concepts in science, with theories explaining a phenomenon and laws describing it. Theories are based on laws, facts, testing, and evidence, and they can be proven or disproven. They are complex sets of statements that offer explanations for how a part of the universe works. For example, the theory of evolution by natural selection explains how organisms adapt.
Laws, on the other hand, are simple facts and formulas that apply universally. They are general descriptions of observations, often framed as mathematical statements. For example, the law of conservation of mass describes the fact that mass remains constant in a closed system.
The line between theories and laws can sometimes blur, and it is challenging to determine when a theory becomes a law. This is because theories and laws are not hierarchical, and they serve different purposes. Theories do not become laws with enough research, and they are not upgraded to laws when found to be correct. Instead, they are separate elements of the scientific method, evolving and refining over time as new evidence and discoveries are made.
Theories are adjusted or discarded based on new evidence, and new theories are developed to fit both new and old evidence. This process involves rigorous testing to ensure the validity of the new theory.
In summary, theories are based on a combination of laws, facts, testing, and evidence, and they provide explanations for observed phenomena. Laws, in contrast, are descriptive and do not explain why a phenomenon occurs. The relationship between theories and laws is complex, and they evolve independently of each other, with theories often building upon and incorporating existing laws.

Laws describe an observed phenomenon
In science, a law is a description of an observed phenomenon. It is a simple statement that is always true under certain circumstances, and it does not explain why the phenomenon exists or what causes it. For example, the law of gravity states that if you let go of something, it will fall, but it does not explain why this happens.
Laws are typically derived from a small number of mathematical assumptions and are often framed as mathematical statements. For example, Ohm's Law, which states that in an electrical circuit, amperage is equal to voltage divided by resistance, can be written as the formula I=V/R.
Theories, on the other hand, explain the phenomena described by laws. For example, the theory of gravity attempts to explain why objects fall when they are dropped. Newton's Theory of Gravity did a good job of this, but Einstein's Theory of Relativity provides an even better explanation.
It is a misconception that theories can be upgraded to laws with enough research. Laws and theories are separate elements of the scientific method, and they serve different purposes. Theories are complex sets of statements made up of facts, data, laws, and hypotheses, and they can be proven or disproven through scientific methods. Laws, on the other hand, are simple descriptions of observations that do not change.
It is important to note that both laws and theories can evolve and be refined as we learn more about the universe. For example, discovering new evidence may lead scientists to adjust a theory to fit the new evidence, or it may require the development of an entirely new theory. Similarly, while laws describe observed phenomena, the implications of a law may change if the circumstances change.

Theories explain the phenomenon described by laws
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Scientific theories are not guesses, but reliable accounts of how a certain natural phenomenon works. They are complex sets of statements, made of facts (or data), laws, and hypotheses. Theories are testable and make verifiable predictions. They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific contexts.
A scientific law, on the other hand, is a general description of observations or a unifying concept. It is a specific statement based on empirical data, and its truth is generally confined to a certain set of conditions. Laws are typically derived from a small number of mathematical assumptions. They do not explain why a phenomenon exists or what causes it. Instead, they describe what is observed. For example, the law of conservation of mass describes a fact but does not explain why it is the case.
Theories and laws are supported by a large body of empirical evidence that is accepted by the majority of scientists within that area of scientific study. However, they are not the same thing. While laws are descriptive, theories are explanatory. Theories explain the phenomena described by laws. For example, Newton's Law of Gravity mathematically describes how two different bodies in the universe interact with each other, but it does not explain what gravity is or how it works. It was not until Albert Einstein developed the theory of relativity that scientists began to understand the concept of gravity.
Theories can be modified and ultimately rejected if they cannot be made to fit new scientific findings. In such cases, a more accurate theory is required. However, some theories are so well-established that they are unlikely ever to be fundamentally changed, such as the theory of evolution. Similarly, laws are not set in stone and can be overturned if new evidence contradicts them. For example, some of Newton's laws are known to be incorrect, but they are still referred to as laws.

Laws can be overturned or changed with better evidence or more data
It is important to understand the difference between a law and a theory. In science, a law is a simple fact or formula that applies universally, describing an observed phenomenon. It does not explain why the phenomenon exists or what causes it. On the other hand, a theory explains a phenomenon and is a set of tested propositions commonly accepted as correct, used to predict and explain a class of phenomena. Theories are based on a variety of scientific laws, facts, testing, and other evidence, all of which fit together to explain how part of the universe works.
Laws and theories are separate elements of the scientific method and are not hierarchical. They are different tools used for different purposes. Laws are not set in stone and can be overturned or changed with better evidence or more data. For example, Newton's laws are not entirely accurate, yet they are still referred to as laws. As our understanding of the universe grows, theories may be expanded or refined, and occasionally, new evidence is so profound that old theories are discarded, and new ones are developed and tested.
The misconception that theories become laws with enough research is not accurate. Laws are a starting point for scientists to ask further questions and develop theories. For example, the law of gravity states that if you let go of something, it will fall. However, the theory of gravity attempts to explain why this happens. Newton's theory of gravity was widely accepted, but Einstein's theory of relativity provided a better explanation.
Theories are not upgraded to laws, and laws do not become theories. They are two distinct elements of the scientific process. Laws are descriptive, and theories are explanatory. For instance, the law of conservation of mass describes a fact but does not explain why it is the case. In contrast, the theory of evolution by natural selection explains how organisms adapt but does not describe a law.
In conclusion, laws and theories are integral to the scientific understanding of the world. They are separate but complementary, and neither is superior to the other. Laws can be overturned or changed when better evidence or more data are presented, leading to a refinement of theories or the development of entirely new ones. This self-correcting nature of science ensures that our understanding of the universe remains dynamic and responsive to new discoveries.

Frequently asked questions
Changing a law involves a lengthy process that varies across different governments and branches of government. In the US, a bill (a proposal for a new law or a change to an existing law) can be proposed by a sitting member of the U.S. Senate or House of Representatives, during an election campaign, or by citizens who petition their representative. The bill is then assigned to a committee, researched, discussed, and amended before being put to a vote. If the bill passes in one body of Congress, it goes through a similar process in the other body. Once both bodies accept a bill, they must reconcile any differences between the two versions. The president then considers the bill, and can approve it, veto it, or refuse to sign it, resulting in a pocket veto. If vetoed, Congress can vote to override the veto.
Scientific theories are modified or replaced when new evidence or interpretations of existing data emerge that better explain observations. This process can be controversial and may take time as scientists debate the interpretation of data and the relative merits of different theories. Eventually, the more accurate scientific explanation will be accepted. For example, Albert Einstein's theory of special relativity superseded classical mechanics by explaining more phenomena, including the movement of large objects and new observations relating to electricity and magnetism.
In science, theories are predictive models that explain observations, while laws are short excerpts of theories, often presented as formulas. Theories are tentative and subject to change as new evidence emerges, while laws are absolute and unchanging. For example, the famous law of science, f=ma, only makes sense as part of a larger theory of motion and force.
