Scientific Laws: Immutable Or Theory-Driven Evolution?

Scientific laws and theories are two different concepts in the world of science. A scientific law is a description, usually mathematical, of a natural phenomenon, such as gravity. On the other hand, a scientific theory is a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses. This means that theories are supported by evidence and can be tested and used to make predictions. Theories do not become laws, but they can change over time as new evidence and observations come to light, leading to the proposal and acceptance of new or modified theories.

Scientific theories are supported by evidence and can be tested

The scientific method is a process of investigation that involves making a hypothesis, testing it, and then forming a theory. A scientific theory is a "well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses." In other words, scientific theories are supported by evidence and can be tested.

For example, the theory of evolution is supported by extensive evidence from fields such as biology, genetics, and paleontology. It has been tested through various methods, including fossil analysis, DNA sequencing, and observations of species in their natural habitats.

Another example is the theory of general relativity, which explains gravity. This theory has been supported by evidence from experiments, such as the famous Eddington experiment in 1919, which tested the theory's prediction that light would bend in the presence of a massive object like the Sun.

Even the most accepted theories in science are still subject to revision if new evidence emerges that contradicts or challenges the existing theory. This process of theory change often involves interpreting existing data in new ways, incorporating new results, and generating new predictions. It is a community effort that involves feedback, experimentation, observation, and communication among scientists.

It's important to note that while theories can change and evolve, they do not become scientific laws. Scientific laws provide a description, often mathematical, of a natural phenomenon, such as the law of gravity, which describes and quantifies the attraction between two objects. Theories, on the other hand, provide explanations for these phenomena and can incorporate multiple laws, facts, and hypotheses.

Theories are the end goal of science, not laws

The scientific process typically begins with a hypothesis, which is a guess of what might happen. Scientists then investigate this hypothesis, following a line of reasoning to formulate a theory. A theory is a "well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses." Theories are supported by evidence and can be used to make predictions. They are the end goal of science, not laws.

This is because laws and theories serve different purposes in science. A law is a description, often mathematical, of a natural phenomenon, such as the law of gravity, which describes the attraction between two objects. However, it does not explain what gravity is or why it works. That explanation falls into the realm of theory, such as the theory of general relativity, which explains gravity.

Both laws and theories are based on tested hypotheses and supported by empirical data. They are widely accepted within their respective disciplines and help unify a particular field. However, it is important to note that neither scientists nor nature "conform" to a law. A law does not dictate what scientists or nature must do.

While laws and theories are both essential in science, they have distinct roles and should not be considered interchangeable. Theories are the culmination of scientific inquiry, providing explanations and predictions about the natural world, while laws describe and quantify specific phenomena within that world.

Laws are descriptions, often mathematical, of aspects of the natural world

The laws of nature are descriptions, often mathematical, of aspects of the natural world. They are statements that are based on repeated experiments or observations, which describe or predict a range of natural phenomena. For example, the law of gravity describes and quantifies the attraction between two objects. However, it does not explain what gravity is or why it works in the way it does.

The formulation of modern and valid statements of the laws of nature dates back to the 17th century in Europe, with the advent of accurate experimentation and the development of advanced forms of mathematics. During this time, natural philosophers such as Isaac Newton were influenced by the religious view that God had instituted absolute, universal, and immutable physical laws.

Within metaphysics, there are two competing theories of the laws of nature. The Regularity Theory posits that the laws of nature are statements of the uniformities or regularities in the world and are mere descriptions of the way the world is. On the other hand, the Necessitarian Theory suggests that the laws of nature are the "principles" that govern the natural phenomena of the world. This means that the natural world "obeys" the laws of nature.

Regularists view statistical laws of nature as descriptions of the world, not prescriptions or disguised prescriptions. For example, Gresham's "Law" is purely descriptive and illustrates that laws of economics are not causal agents. They do not force the world to be a certain way. Similarly, laws of nature are not causal agents that force people to behave in a certain way. Instead, they are true descriptions of the events that occur in the world.

Mathematical models are used to describe the laws of nature in the virtual world and provide the source of the world's physics. These models are sets of equations that describe the possible actions that can take place in the virtual world and when they can occur. They are the enforcers of the laws of nature in the virtual world.

Theories can change, and this is a community process

Theories are a fundamental aspect of scientific endeavour, and they can indeed change. This process of change is driven by the scientific community's collective efforts and evolving understanding.

The scientific method involves formulating a hypothesis, which is then tested and, if supported by evidence, accepted as a theory. This theory then becomes a scientific law. However, it is important to note that a theory does not simply become a law; it undergoes rigorous testing and must be well-substantiated. According to the National Academy of Sciences, a scientific theory is a "well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses."

The key characteristic of scientific theories is that they are always supported by evidence and can be used to make predictions. They are not static but dynamic, evolving as new evidence emerges or when existing evidence is interpreted differently. This evolution of theories is a community process, involving the collaboration and contributions of numerous scientists over time.

For example, the theory of evolution, proposed by Charles Darwin, has undergone numerous modifications as new evidence has been discovered and interpreted. This process has involved the work of countless biologists, palaeontologists, and other scientists who have built upon and refined the initial theory.

Theories can also change through community engagement and collaboration. For instance, in community psychology, theories such as Kelly's ecological theory and Moos' social climate theory have been developed to understand the interplay between individuals and their social contexts. These theories recognise that communities are constantly changing and that this change necessitates adaptation. By involving the community in the research process, scientists can gather continuous feedback and make their theories more robust and applicable to real-world contexts.

In conclusion, theories are not static entities but rather evolving explanations of the natural world. The process of change is driven by the scientific community, which works collaboratively to interpret evidence, refine existing theories, and develop new ones. This dynamic nature of theories is essential to the advancement of scientific knowledge and our understanding of the world around us.

Scientific laws are based on accepted theories

Scientific laws are based on widely accepted theories. Both laws and theories are integral to our understanding of how the universe works. They are both accepted as true by the scientific community and are used to make predictions and advance technology.

A scientific theory is an explanation of the natural world that can be repeatedly tested and verified using the scientific method and observation. It is a well-substantiated explanation that incorporates facts, laws, inferences, and tested hypotheses. Theories are supported by evidence and can be used to make predictions. For example, Einstein's Special Relativity explains the relationship between space and time for objects moving at a consistent speed in a straight line.

A scientific law, on the other hand, is an observation. It is a specific statement based on empirical data, often reduced to a mathematical statement, such as E = mc^2. Laws are simple, true, universal, and absolute. They are the cornerstone of scientific discovery, and if a law did not apply, all science based on that law would collapse.

The process of developing a theory and turning it into a law begins with a hypothesis, which is a guess about what might happen. Scientists then investigate this hypothesis, following a line of reasoning to formulate a theory. Once the theory has been thoroughly tested and accepted, it becomes a scientific law.

It is important to note that theories do not become laws, even when supported by substantial evidence. They are distinct concepts, with theories explaining why something happens and laws predicting what will happen. For example, the law of gravity describes and quantifies the attraction between two objects, but the theory of gravity explains how gravity works and what causes it.
