I thought that was why there's all that stuff talking about searching for a unified field theory or something like that.
F = ma is a very old equation that was never intended to apply to anything except material objects. Applying it to electromagnetic radiation is just outside it's realm of applicability.
So then the speed of light is what it is because it is?
I don't understand the question.
I don't understand the answer. I'm still confused what places the speed of light in a vacuum at 299792458 m/s
It is the basic nature of light to propagate at that speed. It doesn't have a "cause" that anyone knows. I'm not sure what your concern is.
I've just been wondering why light moves at the speed it does.
Because that is the speed that satisfies a derivation of Maxwell's equations I think - but I must check this - don't take it as gospel!
Think of a guitar string 1 meter long tuned precisely to middle C. Pluck it and it will vibrate at a very specific speed, no matter if you pluck it gently or hard.
Electromagnetic radiation in our Universe is the same as the plucked guitar string, its the frequency and propogation of the underlying dimensional reality that is our universe.

I tried to say the same thing...
