I guess I need to explicit with my sarcasm tags...

The mathematical treatments predicted things we have never observed
before. They pointed us in the right direction.

What is the parameter you have to adjust in SR to get the Compton
effect?
What is the parameter you have to adjust in SR to get the increased
half-lives of particles?
What is the parameter you have to adjust in GR to get the Mossbauer
effect?
What is the parameter you have to adjust in GR to get Mercury's orbit
correct?

Well, the last two aren't fair - you don't understand GR. I will be
generous in the assumption that you understand SR enough to answer the
first two questions.

I guess spacetime geometry doesn't satisfy you. I thought geometry was
your specialty...

Again, so what if a physical theory doesn't give you an answer to the
"Why?" question?

They explain, only so far. The reasons are buried within the theory,
but you are right - there is no answer to the ultimate "Why?"
question.

But again, so what? The theory works irregardless of being unable to
answer the ultimate question of Why Things Are.

I get the faint impression you don't understand the math behind E&M.

No.

Science is testable, philosophy is not.

I look to the math, because the math has yet to fail.

You do forget that math is based heavily in geometry. For many things,
R^3 - our flat Euclidian space, is the foundation. Geometry satisfies
me until it breaks, then I look further.

Verges but does not cross. You do realise that coordinate systems
don't always have to be orthogonal, right? It makes the math painful
because dot products of the unit vectors arent 0 anymore.

At any rate, science is testable, philosophy is not.

I think this is a very big deal for you. Dollars to doughnuts when you
asked "Why?" enough, you reached a point where nobody could answer
your question. At that point, you rejected everything because it
couldn't satisfy your insatiable desire for everything having a base
reason.

Either that or at one point someone tossed you an equation you
couldn't handle. Probably a combination of both.

Did you ever once think for a little while about how Einstein's ideas
were accepted? Did you know Einstein's ideas were fought against
viciously? Even after, but less so, after Eddington's expedition?

You are ignorant of history. I suggest you take an introductory
physics class, and spend some time in the library reading about
Galileo, Newton, Kepler, Corpernicus, Lorentz, Einstein, Planck, etc
and etc.
