Somehow the role of science theory has been taken to mean that which has to be studied and inwardly digested, that is not the case. The truth is that theory is a standard model of the universe that all other ideas can be compared with. Everyone would agree that a miriad of different ideas put forward by anyone with any thoughts on the matter would be useless as a model so one standard theory is how everyone can have ideas and compare them to that one model.
There is a difference between fact and theory.
The Moon orbits the Earth in space, that is a fact. If the theory were fact then it would be called the factual model of the universe.
The theory includes fact but not a lot so the rest is made up with what science calls the best possible explantion...and it is the theory that everyone can question but not the facts.
This causes a problem among scientists and everyone else because they have difficulty in sorting the fact from the theory.
The big bang is theory as no one was around at the time to know what happened and in fact no one knows whether there was anything before the universe so that is a best guess supported by seperate indirect fact.
The big bang singularity is theory as no one knows whether such a mass of the universe could be reduced to a point.
Curved space is theory as no one can directly show space is warped.
Stars form and creat new atoms, that is fact and can directly be shown to be factual.
There is a force called gravity that is fact.
What causes gravity is not a fact it is theory.
Stars do orbit black holes at far greater speeds than they should normally that is a fact, what happens inside a black hole no one knows as no one has been inside a black hole so that is theory.
So the test is whether something in the standard model can directly be shown to be fact in which case it is true or whether it cannot be directly shown to be true and then it is only theory.
Scientist and those who study theory have a personal interest in promoting all the theory as fact and that is why they do not differentiate and make clear what is fact and what is fiction.
In particular anything that can only be explained by mathematics is pure theory because fact has to be shown in reality to be the case.
Time cannot be shown to be factual in reality as it has no substance so has no influence on the universe at all.
Having cleared the air on theory it is the culmination of the ideas of many great scientific minds over the years who have also produced the factual scientific breakthroughs and as such is the best model for the theory we have.
