@The_T @jleedev "blue shift" is when you're travelling fast towards something and it causes the light wavelengths to get shorter, where for example red things turn blue (i think)

@casey @jleedev I still don't get it but at least now I know I never will

@The_T @casey it's the Doppler shift except for light not sound

@jleedev @casey presumptuous of you to think I have any idea what that means
