hi there!
Just wondering... if i have a photon moving in the z direction 4 momentum given by (0,0,1,1)
and I lorentz boost it in the z direction... would I get the same original 4 momentum (0,0,1,1) because i thought that boosting something at the speed of light means that it remains at the speed of light right?
in the case of the x direction (1,0,0,1) the lorentz boost in the x direction gives (cosh, -sinh, 0,1)... which isn't the original 4 momentum
could somebody kindly explain what exactly I'm getting wrong here?
Thank you!
