No, the deflection of the photon is an abstract concept that can only be
proven in the mechanism of mathematics.

I don't think you have understand me earlier in the previous post. You can
never observe the bending path of a photon directly. Only in a medium
filled with smoke, which reflects some photons, in a beam of laser you can
see the path of a photon takes. I also think you meant "a light beam in an
accelerated environment appears to bend when examined from flat space.

Your 2nd run is demonstrated by Michelson-Morley experiment. Again, from
the experiment, you do not observe the path of the photon taking a different
route. Rather, the diagrams of how a photon travels relative to other
frames of references are determined through common sense. Your 3rd run
involves acceleration and ALSO SPEED. How do you know it is not the speed
(also variable) that allows a bending path of the photon as MMX has already
authenticated?

To understand this problem, you must go through the math. Although the math
leading to the field equations are extremely complicated and requires
expertise in tensor calculus, after Schwarzschild presented a solution based
on the polar coordinate, everything becomes so simple. And since the motion
of a particle is mostly constraint to a 2-dimensional space, the whole
problem even simplifies further. Don't be intimidated by the math after
Schwarzschild metric comes around.
