how to change a theory into a law?

Answer 1

A hypothesis becomes a law when it is proved practically and thus cross checked by at least two independent experiments, coming to same conclusion.
That is also thus the guideline or one of the guidelines of Nobel Prize nominee & also the winner of course. That is the reason why Einstein never got Nobel prize for his Relativity work (FYI, he got it for photoelectric effect), now after so many years his theory been proved by great follow up work by geniuses like Hawking, but still Einstein will not get a Nobel Prize for "it".Reason, because second clause for this elusive honor is that the person in question must be alive.. :)... Damn, Tough Luck..
Cheers

Answer 2

You're misunderstanding what are meant by "Theory" and "Law." One does not "become" the other.

A Law is a simple statement that is generally incorporated into (one or several) theories, and often becomes one of the "ground rules" on which the theory is based. A theory is generally a much broader framework; a coherent set of descriptions and explanations that may take up a whole book.

For example: Newton's Theory of the behavior of moving bodies takes up a whole book (the "Principia Mathematica"). Within that book are his three Laws of Motion, which act as ground rules that set the stage for the theory.

Once a theory has been regarded as a valid description and explanation of the facts, then the laws that form the basis of the theory are accepted as well. The theory doesn't "change into" the law; they are two separate things.

Answer 3

As the previous answer indicated, laws are hard to come by. Basically, they are theories that have withstood the test of time; so testing them is no longer or rarely done. Laws are axiomatic; no rational person can or will dispute them.

In the grand scheme of things: laws are indisputable and no testing is required, theories are still testable and test worthy, and hypotheses have yet to be tested...usually because they cannot be tested given current technoloty.

So, to answer your question...theory is not changed into law, it just sort of evolves over time into law.

Answer 4

The Laws of nature are set. We can only discover them we cannot produce them out of theory.
A theory is still considered speudo science ii it cannot be applied as a law.

Answer 5

Observation turns into a hypothesis. When things get a bit complex a series of hypothesis becomes a theory. Finally when we find that theory 'holds water' then the parts that hold proverbial water become laws.

I also like Brian K approach.

Answer 6

According to the scientific method laws are hard to come by most all of the scientific knowledge to date is still considered Theory.
