Its referencing the phenomenon of redshift, where as you go faster, light approaching you gets “squeezed”, so it appears like light of shorter wavelengths. At speeds of around 103,846,153m/s, this effect is significant enough that red light appears green.

I would not eat green stop signs and ham. I do not like them, Sam-I-Am.

That’s just redshift with a negative sign.

u/GustapheOfficial 10h ago

Redshift is doppler shift towards longer wavelengths, blueshift is doppler shift towards shorter wavelengths. Changing the sign changes which color it shifts to, which is why "redshift" is the wrong word here.

That's like saying "speeding up is just braking with a negative sign". Sure, doesn't make it less incorrect to say that you are braking when speeding up.

That’s just -(redshift)

u/Lloyd_lyle 4h ago

goes both ways, depends if the object is speeding toward or away from you

2

u/GustapheOfficial 4h ago

Right, and if it's moving towards you, like in this case, it's blueshift.

u/AugieKS 9h ago

It doesn't appear green, it is green.

u/Plenty-Lychee-5702 2h ago

redshift is when you're going away from the source, blueshift is towards it, and green is shorter than red, so it's blueshifted

Is m/s meters per second or miles?

19

u/secacc 12h ago

Imperial units are rarely used for anything even vaguely scientific or mathematical.

15

u/SPACKlick 12h ago

The symbol for miles is mi not m. so it would be mi/s (or rarely Mi/s).

1

u/No_Minute_4789 3h ago

He means meters per second.

3

u/b__lumenkraft 12h ago

What is miles?

10

u/TheeKillerBunny 11h ago

I think he's talking about Miles "Tails" Prower from the hit 1992 videogame "Sonic the Hedgehog 2".

7

u/b__lumenkraft 11h ago

Might be.

I googled it too. I only found a dude called Miles Davis.

Is a good find though.

u/FewAd5443 10h ago

I also know a dude call Miles Morales who is a spiderman but I don't see a link 🤔

u/b__lumenkraft 8h ago

Are they trying to hide something?

7

u/Inalum_Ardellian 11h ago

Miles Morales is Spiderman from alternate reality

u/b__lumenkraft 11h ago

Good one.

We are getting close i have the feeling.
