I think that guy is speeding

[-] Posadas@hexbear.net 10 points 1 year ago

He can go over c as a little treat.

[-] TonyTonyChopper@mander.xyz 8 points 1 year ago

1-2% the speed of light

[-] Chais@sh.itjust.works 18 points 1 year ago

For extremely low values of c.

is this a Doppler effect meme or something I'm stupid

[-] Skua@kbin.social 18 points 1 year ago

Yes, but rather than regular Doppler effect it's the relativistic one. The car is being blueshifted in the first panel and redshifted in the second but it's the same general idea as the change in pitch as a car passes

[-] MxM111@kbin.social 7 points 1 year ago

If it were relativistic, the car would be relativistically compressed in both panels, not just in the first.

[-] Skua@kbin.social 5 points 1 year ago

It's pretty easy to get the idea that redshift and blueshift would apparently lengthen and contract an object if you look at diagrams of it. I'm not going to fault a comic for not getting relativistic physics completely 100%
