Does anyone know any evidence besides time dilation and Lorentz transformation that support the correctness of the Minkowski spacetime model? Thanks!

I saw this solution a while ago: dN donates the number of photons in a certain space, f donates the occupation number, g donates the number of spin states, p donates the dimensional momentum, dt, dA, do, dE donate unit time, unit area, unit angle, and unit Energy. dN = f * g * (d3r * d3p) / (2*pi*h)3 Since d3r = c*dt*dA, d3p = p2*dp*do Intensity I = (E * dN) / (dt * dA * do * dE) = (c*f*g*p3)/(2*pi*h)3 Therefore, the change of the brightness of the stars when moving at velocity v is proportional to p3, which is the cubic of the doppler effect factor.

Thank you so much!

Sensei, could you please elaborate a little bit? Thanks!

When you are moving at a large velocity, v, the brightness of the stars changes. Does anyone know the ratio of the brightness of the stars in the primed frame to which in the unprimed frame?
