Space and shit
i like the deeper purple and blue ones better
Apparently that's the most realistic conception of a OP's anus, aka black hole, without the Doppler Effect of course.
I think that's the name of the effect, i can't remember...
Doppler applies to any waveforms
Yes, it is most easily observable as we hear sound waves easily (a truck passing by)
But it has an effect on light waves as well, and as light travels, it undergoes a "red-shift" as the wave length is stretched depending on both perspective and things interacting on the wavelength (the black hole's gravity)
Source: My general understanding, correct me if i'm wrong but i think that's a high level understanding
Pape for your time
is there a minimalist-esque version of this, that would be cash
