Theory
A scientific theory is an idea that is supported by a hypothesis. Once the theory is proven to be permanently correct, it is a law or fact.
In short, a theory is simply a group of ideas. This group of ideas are used to explain a certain topic such as a fact, event, or phenomenon.
One of the most major influences of Albert Einstein was the fact that he made us enlightened about the theory of relativity. He also discovered the theory of light.
Particle theory, as opposed to string theory.
A "theory" is a scenario of what might be.
The opposite of theory is typically practice. While theory refers to a set of principles or ideas used to explain something, practice involves the actual application or implementation of those principles.
This is a fact.
One is based on scientific data the other is based on the unproven.
Evolution is both theory and fact. Moreover, the fundamental theses of the theory (common descent, natural selection) are so well supported by fact that they might as well be called fact.
A clue is a datum - a fact. A "theory" tries to tell you what the fact means.
It is not a theory, it is a provable fact.
theory can only be a best simulation based on a formula. Fact is material proof

Theories tend to Remain a Pseudo Fact, until proven otherwise, the theorist, is under no obligation to Prove his Theory, which makes anyone capable of writing a Theory, without using any Facts whatsoever. Of course it's always advisable to throw a few facts around within the Theory, to add some Credibility to your Theory. Remember if you could prove a theory as Fact, then it would no longer be a Theory, but a Fact.
