Physicists invented negative time and then try to understand its existence.
Time exists only in the third dimensional gravity reality ( like planets )
Time exists only as a result of the process which was explained in SRT and GRT .
Time doesn't exist outside third dimensional gravity reality.

" Einstein's theory of special relativity followed a series of perplexing experiments . . .
. . . . . . . . . .
Einstein showed that drastically revising the basic concepts of space and time
led to a consistent description of all these perplexing experiments . . . . ."

In the others words, according to Einstein
because the space and time different from Newtonian
is possible the phenomenons of SRT.
I give another interpretation:
the phenomenons of SRT are possible because behavior
of quantum of light allow them be appeared.
The behavior of quantum of light is the cause of SRT's phenomenons.

" Einstein's special theory of relativity is based on two postulates:
One is the relativity of motion, and the second is the constancy
and universality of the speed of light.
Could the first postulate be true and the other false?
If that was not possible, Einstein would not have had to make two
postulates. But I don't think many people realized until recently
that you could have a consistent theory in which you changed only
the second postulate."
/ Lee Smolin, The Trouble With Physics, p. 226. /
It means that speed of light is a constant but not an absolute constant.
The speed of quantum of light is independent ( doesn't depend on outside forces )
Quantum of light can itself change its speed ( by own impulse / spin )
Therefore SRT is theory about behavior of quantum of light

The concepts of space and time must be basic in physics.
But these conceptions didn't solve until now .
From the one hand, according to SRT, both space and time relative . . . .
From the other hand, according to SRT, 4D spacetime is an absolute continuum.
And nobody explains what negative 4D really is by ordinary logical language
and therefore . . . . . .

The speed of light varies it is not constant from an observers view. This is due to the varying force of gravity. I believe your opening posts were somewhat accurate in the geometry of a photon. The crests of the sine wave must stretch and elongate the photon's EM wave as it travels outward from gravity. Lets say it has had no force from gravity in several million light years, How long is it now? I don't know. But perhaps this is the CMBR we hear now. Now let that photon come toward earth. The force of gravity slows the front down and the length contracts. We measure the frequency, it's wavelength, ect. as if it was always this. There is no way to not to bring gravity into the measurement as all things have mass which have gravity, including our instruments for measurement. The difficult thing I can't understand is why the amplitude is constant?!Comment

The two postulates of special relativity are bound together.
1. - The laws of physics are the same in all inertial frames of reference.
2. - The speed of light c is the same in all inertial frames of reference.
