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.
Scientific observations and experimental results are required for a theory to be scientific.
A "theory" is a scenario of what might be.
A clue is a datum - a fact. A "theory" tries to tell you what the fact means.
The fact that it's required to even begin to understand fundamental theory in all of them?
It is not a theory, it is a provable fact.

Fact
A significant theory is one that can be supported by relevant material, in which the theory you are proposing is in fact a possibility.
In science, a theory is, by definition, proven and accepted as fact.
The natural tendency of a moving object is to keep moving. And it doesn't really require energy to stop it; in fact, in theory, you can gain energy from it. What is required is a force.
