Every model is wrong. Some are useful.

All models are shit. Some of them are useful tho

I think anyone who uses the word "literally" to mean anything other than "in a literal sense" is a moron who never actually thinks about what the words coming out of their mouth mean, and I always will.

To be perfectly fair, you can't "prove" or "disprove" a theory. You can only discover new evidence that supports the theory or another competing theory. Multiple competing theories can be equally accepted as correct.

If you consider gross misuse (i.e. mixing up "theory" and "hypothesis") to be a valid form of etymology (e.g. making new words), I have a question to axe.

(I apologize to linguists' families who now have to clean up bodily fluids and/or arrange a funeral.)

A law describes what happens, a theory explains why. The law of gravity says that if you drop an item, it will fall to the ground. The theory of relativity explains that the "fall" occurs due to the curvature of space time.

In physics we call some results "laws" and some "theories." The difference has absolutely nothing to do with our certainty in the validity of the results.

Newton's Laws of motion are called that because they can be written as concise mathematical equations, and allof the content is there. Einstein's Theory of special relativity is just as valid, and even contains Newton's Laws as a special case, but the content of the theory can't be written in simple, concise equations. There are several equations included in special relativity, but they do not represent the entire content. For example, the most important statement of the theory cannot be written in equation form at all: "The measured speed of light in a vacuum will be the same for all observers in inertial reference frames, regardless of the relative speed of their reference frame."

Darwin's Theory of Evolution likewise cannot be written in concise statements (mathematical or otherwise), but our certainty in its validity is no less than in Newton's Laws.

Another important subtlety: I was careful to say that we are certain of the validity. People who don't know better are fond of saying that Newton's Laws are wrong. This is a fallacy. Scientific laws and theories can only be valid or not, they can never be true.
