Supplementary stuff to the chapter “the dynamic vs the gravitational vs the static”:
(In the X4 Theory, the released photon is in a very special matter state and it must be treated in a special way.)
The dynamic situation:
Light speed is an invariable in different inertial frames. That means the kinematic energy of a released photon does not change in different inertial frames: Ek = Ek’. Also its internal energy does not change in different inertial frames: E = E’. According to Energy – Space equation, the 3D physical space does not change in different inertial frames; according to Energy – Time equation, the time does not change in different inertial frames: L = L’; △t = △t’.
So, L / △t = L’ / △t’. Namely c = c’. It means light speed is an invariable in different inertial frames. No contradiction.
The gravitational situation:
If a released photon travels from the ground to the top of the Pizza tower, its gravitational potential increases. And its internal energy decreases (note: its kinematic energy also decreases). According to Energy – Space equation, the 3D physical space inflates. Its wave length stretches. This point could be verified by the gravitational red shift phenomenon. According to Energy – Time equation, time contracts.
At this moment, piggy wants to talk a bit about the light speed in gravitational field. We had some discussions in this respect in PHF:
Piggy agrees that light speed does not change in gravitational field.
It demonstrates that the employment of velocity to control space – time is not sufficient enough. Energy / mass might be a better player.
The static situation:
In my physical model, the released photon is a section of electromagnetic wave, different matter state from other elementary particles (spherical electromagnetic wave). It can’t sit, and must travels in light speed c. So, there is no a static situation for the released photon.
The cosmic environment situation:
If the cosmos is expanding, the mass density of the cosmos now is much smaller than that of billions of years ago. According to the mass space equation L ∝ 1/ρ, the 3D physical space of the cosmos is much different than that of billions of years ago. That means when light from a remote galaxy reaches the Earth today, its wavelength has been stretched significantly. Piggy has talked about this point ahead.
