When you say a theory is close to becoming a law it seems like you don't at all know what you are talking about because they are completely different. I apologise if my tone offended you, which I did not intend, but your post, which claimed to be pedantic, seemed muddled.

No they don't. There is no Newtonian theory of gravity. Such a thing does not exist. Newton is actually quoted as saying something to the effect that any explanation of the source of gravity is up to god. That is to say he approached it from a purely mathematical stand point and left it there. With the caveat that he did say his math worked best if gravity was the same everywhere and instantaneous. Neither of which are explanations just limitations on the mathematics. I have no idea where you are getting this law of gravity except perhaps as a mistranslation.
Again only the law of gravitation exists. There is no such thing as either the theory or law of gravitation. There is the theory of general relativity which is sometimes called the theory of gravity. However, there is no accepted law or theory from Newton's day that deals with gravity, only gravitation. There certainly isn't two forms of the law of gravitation one dealing with the math and the other theory. Further, once again please avoid explaining things to me that both clearly need no explanation and which I have not brought into question to begin with. (ie. I clearly delineated the exact same relationship between theory and law as you did and yet you felt the need to explain it like I was wrong which is highly annoying)

I'm not talking about Newton, I'm talking about our theory of gravity, how we understand (or don't) gravity to work.
If you're going to complain about me misinterpreting your posts about things you know, I going to complain about you misinterpreting my posts about things I know as I'm very much more a historian of science than a scientist and part of my thesis was on British science.
I was talking about our "theory" of gravity as a subset of relativity not Newton's though I probably didn't make that clear as gravity is really a subset of a larger theory.

We'll have to disagree there but probably because I'm using law as having two different meanings which is confusing. When I say a theory is almost a law I mean a theory is almost as metaphysically certain as a law. A condition which I theory can approach asymptotically but never actually reach.
|
While I accept that as a valid standpoint I'm going to have to strongly disagree as my own position is completely opposite.
Quote:
Perhaps but everyone inside the scientific community does it when discussing things with people outside the community because its easier than trying to explain the subtleties of meaning given to the term theory. It serves as a quick and easy way to distinguish a theory that isn't likely to ever change from something more fluid like super-gravity or string theory.

Fair enough. I'm too used to my own group of geeks and nerds who know all the terms.
Quote:
Again I was not implying you could change a theory about why into a mathematical law through evidence. Though the two approaches can give equivalent results and as such there are methods to translate from one to the other. I was implying that certain theories have advanced to the point of nearly the same metaphysical certainty as mathematical laws like 1+1 = 2.

Yeah I think this is more a philosophic difference than a semantic one as I don't hold that theories can approach that but I can see how you could.
I didn't mean to offend you but I geniunely misinterpretated your post.
