Below, this tramp in cosmos plays that math game in counter way. Perhaps more tricks can be displayed.
E = mc² is Dynamic mass – energy relationship in nature. It’s a basic natural property. (“Dynamic” means the particle is moving and hints it has momentum);
Next square both sides: E² = m²c ^4, namely: m²c² = E² / c², then, add a negative mark on both side: – m²c² = – E² / c²;
Add two Redundant items m²v² on both sides: m²v² – m²c² = m²v² – E² / c²;
Because m²v² = p², then, m²v² – m²c² = p² – E² / c²;
Because m = γm0, (pay attention here, it just means that you can consider the magnitude of the moving mass m is γm0, but not means the particle be rest). Square both sides: m² = m0² / (1 – v² / c²);
Then, m0²v² / (1 – v² / c²) – m0²c² / (1 – v² / c²) = p² – E² / c²;
A mathematical calculation: m0²v² / (1 – v² / c²) – m0²c² / (1 – v² / c²) = - m0²c²;
Then, - m0²c² = p² – E² / c²;
Transform it in math, then, E² = p²c² + (m0c²)².
It’s the so called energy – momentum equation.
If it’s the stationary situation, v = 0, so, no math game can be played. Then, it’s just a stationary mass – energy equation: E0 = m0c².
Gangster's philosophy 1:
In such a basic natural relationship between E and m, why we need a momentum factor artificially added to it? Either in math calculation or physics meaning, it’s just redundant. In philosophy, it’s just “absurd”. In society of human being, this kind of behavior is called “conspiracy”. It might cause a series of serious results, turn simple thing to complicated thing, which might not be solved in decades.
When we talk about the energy – mass equation E= mc², we are talking the basic natural relationship between energy E and mass m. And then, some conspirators artificially add in a momentum factor. After a series of math transformations, the so called energy – momentum appears. And then, the conspirators plot “for a massless particle, E = pc”. Their conspiracy successes. They obscurely hand over energy to momentum while kick mass out. But we originally talk about the basic natural relationship between energy E and mass m. This is the “gangster’s philosophy ”.
Gangster’s philosophy 2:
Some guys might say that “…And Einstein's energy relation for a photon comes down to E = pc, not c².” That guy doubts if Einstein’s energy – mass relationship is correct, why he believes in something extents from Einstein’s energy – mass relationship? This is also the “gangster’s philosophy ”.
