You seem to be treating this like photons are riding the wave. In the case of the two slit experiment, it is the wave function that is described as spreading to both points simultaneously. In other words, it describes the probability of finding a photon at once side or the other, not the...

Thanks. Should have checked this earlier. Lots of useful info here, like the fact that CMB is redshifted. I'll try. It's hard for me to do this easily because I'm usually considering them at the point of emission, at discrete energies, and detection, at discrete energies. Thinking of it...

Ok. So there's two ways we can see the redshift. How would we distinguish between the two in the case of stars? Still confused...

In the case of the bullet, yes. In the case of an individual photon, is that true? It seems that if the photon was produced by the same process in both cases, the only thing that would make it different is the space. Sean Carroll seems to corroborate this in the link I posted. He writes...

That's right. What matters in that case is the relative motion of the two objects. The total energy in the system is defined by this relative motion. The problem for me, is that, if you think about light, it doesn't behave like you'd expect. If I shoot a laser at speed c, it is speed c for...

Hi, I'm confused about how Doppler effect shifts the wavelength of light depending on the speed of the emitter. It makes sense from a classical point of view that the wavelength should shift. However, when I consider that light comes from photons, quantized energy, any shift in frequency...
