Theory against the law

Theory and law are interconnected. It is a common misconception that these two options can be used alternatively. Now let's take a closer look at each of them.

lawAccording to science, the law is a generalized statement established after a series of observations. The law has no explanations or exceptions if it is drawn up. This is an obvious fact, recorded after observations. A good example of this can be gravity. It is observed that the apple falls on the surface of the Earth. This is an indisputable fact. There are no exceptions to this observation. No one has ever observed the opposite or alternative phenomenon. Therefore, it is considered law. There is another misconception about the hierarchical level of law. A group of scientists believes that there is a hierarchy of hypothesis, theory and law, but this is only an erroneous statement. Laws are obvious and simple statements.

theoryA theory is an explanation of observational data presented in the form of a law. In simple words, theory is an argument in favor of the law. It can also be posed as an extended or developed hypothesis. A “hypothesis” is the probable cause of any observation. The hypothesis must pass various tests. If a hypothesis holds well in different conditions, it can be accepted as a theory.

Given the previous example of the law of gravity, in 1687, Sir Isaac Newton put forward the law of the inverse square in his journal. This was until then a hypothesis. This law has been tested by various scientists in the study of planetary motion. The hypothesis held well with some planets, but there were exceptions. At this stage, Newton's hypothesis was accepted as the theory of "gravitational theory." This theory was later replaced by Einstein's theory of relativity.

A theory can be strong if it has a lot of evidence of its support. It can also be regarded as a weak theory if the level of accuracy in its prediction is low. A theory can become obsolete over time and replace it with a better one. However, the law is a universally recognized fact. This is beyond doubt, and never fades away with a stretch of time.

1. The law is an observation, the theory explains this observation. 2. Theory requires experimentation in various conditions. The law does not have such requirements. 3. Theory may become obsolete over time. This does not apply to the law. 4. The theory may be replaced by another better theory, but this never happens to the law. 5. The theory may be strong or weak depending on the amount of evidence available. The law is a universally recognized fact.

## What is a hypothesis?

Understanding what a hypothesis is and how a hypothesis differs from a law or theory will help the definition of this term. A hypothesis is the opinion or assumption of one or more scientists in which they try to convey their belief about the effect of the phenomenon. Such an assumption is not factual and requires proof. Therefore, scientists conduct various experiments, experiments and in every way investigate the phenomenon. There are always disputes around hypotheses, and some scientists support them, while others, on the contrary, are opposed.

The hypothesis is still perceived as scientific knowledge all over the world, although it is known that it is not fully proven. So, for one phenomenon, several hypotheses can be put forward by scientists. Take, for example, the fact of the origin of planet Earth or the entire universe. There are many hypotheses and assumptions on this score, but not one has been proven yet. The first difference between a hypothesis and a law or theory is that science as a whole cannot exist without it, because thanks to it there is a movement in the development of the scientific environment. It generates new knowledge.

## Definition of law

The law is a hypothesis or assumption, which is confirmed by facts in mathematical or verbal terms. It describes the relationship of certain phenomena. Law is the goal of scientific knowledge. It is universal, and the sentences in it are true. That is, the existing law should act in this field of science in all cases the same way.

There is an identical concept to the law - the theorem. Both of these knowledge scientists have passed all the tests and have been proven, so it makes no sense to test them. This is what is recognized by the scientific world and is valid for everyone, without a doubt. The law and the theorem are related to the foundations of science, on the basis of which studies of other unexplored phenomena are carried out. The second sign, how the hypothesis differs from the law or theory, is that the first acts as a certain thought, point of view or idea. But the law is nevertheless confirmed by facts - this is a certain exact concept.

## Theory and its meaning

In a conversation, it is generally accepted that a theory is just words that are not confirmed by anything. In fact, a theory in science includes practical and laboratory research that confirms its description. Research can be carried out more than once by different scientists, but the rules and axioms will be confirmed. It cannot contradict, and knowledge is true. It is used by scientists for various studies of phenomena.

The theory includes principles, ideas, and ideas. It explains the relationships and properties confirmed by law in a particular scientific field, on which the explanation of the theory itself is based.

Law and theory do not differ too much from each other. In simple terms, the law is the concept of a specific exact case. A theory can cover several directions in one field of science at once.

## Differences between concepts

Now that the definitions are given to all three concepts, we can summarize and answer the question of how the hypothesis differs from the law or theory briefly. An assumption may translate into law or theory if facts and evidence are provided. The research begins with the scientist’s assumption, and after a while (sometimes centuries pass to find the truth), it transforms into one of two concepts. But on the contrary, the process cannot start. Law or theory will never become a hypothesis. This will be the third sign and answer to the question of how the hypothesis differs from the law or theory.
