# Theory vs. Law

The scientific method is the comprehensive method of checking the validity of the various phenomena and statement.  In science we came across two terms, theory and law. The theory is the well-substantiated explanation of natural phenomena, the evidence backs it, and at the same time, it is testable and false. Contrary to this, a law is the concise statement comprising of facts. In other words, we can say that law is the established absolute fact.

## Key Differences

Theories explain the phenomena and try to back them with logic and evidence. Contrary to this, law defines the phenomena in a general way.

The theory is the well-substantiated explanation of natural phenomena, the evidence backs it, and at the same time, it is testable and false. On the other hand, the law is the universally accepted statement based on truth; it also describes what nature does under different conditions.
A theory may get outdated or replaced by the other one while the law doesn’t get replaced.

### What is Theory?

A theory is a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained. The theory is backed by certain prove and can be testable and false able. It is based on the proven factors after the strong research, and the scientific results came up with the similar results after checking it numerous times. As science is the search for truth, the theory is the answer to it which response to the answers like why and when. According to the experts, the theory is the set of principles about the phenomena; they are the group of facts that can be tested through the proper channel. A statement backed by some evidence doesn’t turn out the theory immediately; it is cross checked by the different scientists. The scientist does the repetitive experiments, and then the collective proposition leads to the theory. A good theory should have the quality to explain the different components of the scientific method, observation, and the experiments such words that they are even understandable by the layperson.

### What is Law?

A law is a solid state based on facts, according to the belief of some of the scientists, it is said that law comes in hierarchal order in the scientific method followed by the hypothesis and the theory. Another famous definition of law tells that it describes what nature does under different conditions. The law is an absolute statement that is based on facts, and it explains the phenomena in the general way rather than doing it specifically. The law can’t be outdated or discarded as it turns out to be the universally accepted truth. In rare cases, certain additions were made in the law, but most of the time it remains unchanged. Newton’s Law of motion, Boyle’s Law, and Charles Law are some of the prominent laws in the history of science. According to some of the scientists, when the strong evidence backs a theory, and the hypothesis get supported in different conditions, then it turns out to be the law.
