It's a photon. Photons always have speed = 1C.

- StevenHarlow 3y agoTechnically no, photons don't always have a speed of 1C, as C is the speed of light _in a vacuum_. In more dense matter the speed of light will slow down.
- uoaei 3y agoTechnically true and also completely irrelevant for this thread.

- rainbowzootsuit 3y ago"If the emitter is coming towards us that would blue-shift photons," is, I think, the point of the previous person's comment.

- lazide 3y agoBlueshift == relative speed difference, which manifests for a photon in the form of more energy in the form of a shorter wavelength no? Gamma rays being an extreme example. That much blueshift means that much more relative speed towards us. Redshift being the corresponding speed difference ‘away’.
