The term "theory" is only used to mean an assumption by laypeople. It is absolutely never used in science like this.
Germ theory, theory of gravity, Doppler theory, theory of special relativity, theory of the combustibility of oxygen, information theory, quantum theory....
...theory of magnetism, game theory, theory of general relativity, theory of heliocentrism, and many, many more are concrete facts, not these so-called "alternative facts" that exist only for people who really want to being Euclid's theorum is wrong and that there is only a finite amount of prime numbers. These things are not going anyways, they are not "tomorrow's conjectures," and I suggest you take the time to read what theories actually are and how science uses them instead of going on about things that are so blatantly false.
