It is still valid. I honestly believe in Newtonian Gravity being the

description of gravity in the domain in which it applies.
I don't believe it. I demonstrated it when I did my labs.
You still believe it is the _best_ description of gravity. Tomorrow some
one
Einstein
may overhaul Newtonian gravity and explain that it is actually incorrect
because of [insert reason here].
General relativity, as demonstrated in the orbit of Mercury.
But even that cannot be entirely correct, as it is incompatible with
quantum
mechanics.
But it certainly makes Newton's formulation not-the-best.
Newtonian gravity is perfect at what it tries to describe.
Cool, it's perfect when it's perfect; otherwise, it's not.
Got it.
The very use of the term, perfect, should be removed from our
vocabulary. We don't ever have the perspective to even use it.
Anyway, it's not complicated or confusing, and you know it, John. I
hope you weren't implying anything. Theories evolve in our mental
space and not in perceptual space and we don't always know the
limitations, at first. In fact, it's actually the possession of a
good theory that allows you to then "see" better towards what is left
unexplained and to then go after that.
Sure, it's like a higher-order polynomial being a better fit than a
simpler one. Newton's equations lack some small high-order terms.
Einstein's are better.

It's nothing compared to a "friendly physics debate luncheon."To begin, we imagine broader reach simply because we lack perspective
to know better, when first proposing a theory. Then, as various
boundaries are unearthed in our perceptual space via experimental
results, we learn to recognize them and the initially imagined
boundaries contract a little. More encompassing theory may then be
discovered and applied to the same places where prior, more prosaic
theory also applies, but also now to deal with still more.
Of course, you know all this, as you don't need to worry about the
exact solutions to Schroedinger equations in 10^10 dimensional space
in order to use BJTs, nor would you chastise the use of practical and
much simpler theory, such as Gummel-Poon or EM or even just Shockley,
just because they are not perfect.
What you got, "it's perfect when it's perfect; otherwise, it's not,"
discerns nothing useful or new.
As didn't the line I was responding to.
Dang, you guys get serious.
