In Aug 2020, when the what coffin box from what CN tried hard to disturb my normal research in PHF, piggy was thinking seriously about the problem of the so - called “massless particle” and argued fiercely with physicists there. At last, piggy was defeated by the what coffin box from what CN in the thread “the game of match sticks”:
Shortly after piggy left PHF, 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”.
And then, piggy came back to the a2k galaxy and kept on with research on that problem of the so - called “massless particle”. Then, piggy started the thread “How to understand the energy - momentum equation in a natural way” in the Relativity forum:
Piggy pointed out that the so – called energy - momentum equation E² = p²c² + (m0c²)² is actually a tricky math game and such representation as “for a massless particle, its energy E = pc” is just math game too. After analyzed carefully in math, its essence is as below:
If the energy – momentum equation reflects the stationary situation, it is just the mass – energy equation in stationary situation:
E0 = m0c²
If the energy – momentum equation reflects the dynamic situation, it is just the mass – energy equation in dynamic situation:
E = mc²
Since the energy – momentum equation E² = p²c² + (m0c²)² is considered generally applicable (to any particle), the stationary situation E0 = m0c² as well as the dynamic situation E = mc² is generally applicable (to any particle) too.
So, the energy of a particle should be calculated according to the energy – mass equation of Einstein only in physics. If you consider a particle is “massless”, then, its energy will be zero.
So, the so called “massless” particle is meaningless in physics. It does not exist in nature.
There piggy encountered an important guy: Mark.
He said: “@htam9876,
Human 'measuring' capabilities are 'limited' by the structure of their 'set' construct.
Understanding the 'Nature' of 'Everything' was my life's purpose, until I finally understood this.
It's been a great journey - And it led me to 'Now'.
I recommend all souls to partake in my journey - Should (And it will) the opportunity arise.
(Piggy likes to joke: if Mark is controlled by the First Order, that means the human civilization doomed. Haha)
And then, in this sense, the crisis of two conceptions of momentum automatically eliminated:
If you consider a particle is “massless”, then, its energy will be zero. According to the what equation E = pc, if E = 0, then p = 0.
Actually, it’s the same result as the calculation according to the classical conception of momentum p = mv. If you consider a particle is “massless”, m = 0, then, its momentum p = 0.
Such particle with no mass no energy no momentum is meaningless in physics. No game can be played on anymore.
So, piggy agrees that the classical conception of momentum p = mv applicable to all objects / particles: a pig, a rabbit, an elephant, a proton, an electron, a neutrino, a photon, etc.
(From the front view, people can’t draw a long nose. But it doesn’t mean that the pig head has no a long nose. It’s just the limitation of the method / angle of description. )

Piggy believes that except the First Law of Cosmos which created by the First Order (the local dark lords of the Jiangmen city and who who of the Class 914 of the No1. Middle School of Xinhui always try every means to confine piggy as a half - self payment watchman in their small business) never changes, history is ever developing.
