The Philosophy of the Energy – Mass Equation
Einstein derive the energy – mass equation E = m c² with method of Mass Point Dynamics. That means he worked it out from the second fundamental natural system of PRESENCE – PRESENCE.
Here energy E is internal energy. The energy – mass relation also could be considered as a “fundamental natural relation”. The fundamental natural relation is inherent property of matter. It’s the affair in the first fundamental natural system of PRESENCE – PROPERTY. So, there should be a method to derive the energy – mass equation E = m c² from the first fundamental natural system.
Next, I repeat some materials in this thread, exactly, the article of “Research on the Root of Special Relativity” for reference first.
In the Chen’s physical model of elementary particle: elementary particles can be divided into two big categories depending on matter state:
Matter state 1: Spherical electromagnetic wave. It’s the physical model for such elementary particles as electron, positron, proton, etc. Construct a model of spherical electromagnetic wave in this way: circle type of standing electromagnetic wave on any normal cutting plane of the small sphere. Then, the energy of the electromagnetic wave is confined on the small spherical surface (deposited).
Matter state 2: A section of electromagnetic wave travels in straight line in the speed of light c. It is the physical model of a released photon.
A question here is “what’s a rest photon?” With the help of the Chen’s physical model of elementary particle, we can understand it should be “spherical electromagnetic wave” or a part of a “spherical electromagnetic wave”.
Now, recall the simplified model of “spherical electromagnetic wave”: circle type of standing electromagnetic wave. We can imagine an equivalent section of electromagnetic wave travelling in circle. It can serve as the physical model of a “rest” photon.
Next, unfold the circle type of standing electromagnetic wave. We can imagine an equivalent section of electromagnetic wave travelling in straight line in a speed of c. It is the physical model of a released photon …
The former demonstrates the property of mass only, while the latter demonstrates the property of energy. It’s just that thing. The difference is the speed of light c. So, we can primarily consider the Energy – Mass Relationship as the comprehension of those two factors mass and the speed of light c, namely E = mc. But this is not yet sufficient enough because the internal energy is deposited in a spherical surface. The geometric relation between surface and line is square. Then, the exact Energy – Mass Relationship should be E = mc².
How lame this derivation all sounds. But it works.
Seems those two fundamental natural systems are an integrity.

Now piggy doubts whether the pig head understands physics or not as the what coffin box from what CN said in PHF in 2020:

In fact, shortly after piggy left PHF in 2020, a local guy stopped piggy on the street and insisted he had a physics question to ask me. Piggy just replied to that guy: “I know nothing about physics”. Bounce…
