On a first glance, we all expect the transverse Doppler shift and
gravitational frequency shift to be in red. That is observed to have longer wavelength than the origination. This also means the observed photon has a lower energy. However, according to Lorentz Transform, we have E' = (E + B * P c) / sqrt(1 - B^2), where ** E' = observed energy ** E = energy of the source ** B c = speed of the platform when this photon left (vector) ** P = momentum of the photon at the source (vector) In a transverse condition, there are 90 degrees separating the dot product. Thus, B * P = 0 Thus, we are left with E' = E / sqrt(1 - B^2) Since ** E' = h f' ** E = h f, where ** f' = observed frequency ** f = frequency at the source ** h = Planck's constant Then, we have f' = f / sqrt(1 - B^2) Which means the observed transverse Doppler frequency is BLUE shifted despite an observed time dilation of dt'/dt = 1 / sqrt(1 - B^2) Now, since GR does not dwell on Newtonian explanation of gravity, the only way GR can explain a gravitational red shift is through time dilation. However, the transverse Doppler shift tells us that despite a time dilation, the observed blue shift is due to the increase in relativistic mass of the photon. Appling the same concept of time dilation actually gives an increase in relativistic mass, we should expect GR to predict a gravitational BLUE shift instead. |
