That's the same for everybody. Not sure math must dominate though.
Einstein once wrote of "mathematical torment" while pursuing the
unified field theory, his sense of the universe was subsumed by
math.
  IMHO math is the legalese of physics, and physics does require
precision of communication when ideas get complicated. Hand
gestures don't work (I just waved at you :).

Who said anything about certainty, I'm an old hound-dog doing
what comes natural, chasing a scent, I smell something fishy??.

>What conditions would make it not a constant?

It would become noticeable at higher speeds and energies.

  What occurs (to me) is a relativistically induced dimensional
deformation, that in simple SR terms, makes dimensions to have
different mesurements for a moving observer' compared to a rest
observer, along the lines of, (gamma = 1/sqrt(1 - v^2/c^2)),

  L' = L / gamma ((Lorentz Fitzgerald contraction))

  T' = T / gamma ((Time dilation))

  M' = M * gamma ((Mass increase with velocity))

The weak limit of GR is very nearly SR applied to Newton's
gravity. So this in a weak g-field is

  Acceleration = L/T^2 = G*M/L^2

Dimensionally, where SR is concerned, becomes equivalent to,

  Acceleration = 1/T = G/L^3,

where the M == 1/L, and the T == L are equivalent transformations.

  From that we obtain,

   G = L^3/T == L^2

meaning that G transforms like Length squared. But L is relative
therefore G ought to be as well, IOW's the measurement of G depends on
on the relative velocity of the observer, and is NOT a constant
in the same sense that "c" is found to be.

Pax, if you're ok with algebra then the above will be clear, if
anyone else who is reading this post thinks I'm misleading Pax
please inform her, I'm interested!

Ever get a thank you note from the government when you paid

The fourth kind aren't even in this universe.
