(guy that read all of these)
Dude, it's almost like if everyone commenting on it more or less understands what it is about, but everyone is explaining it.
I usually peruse comments of things I stumble upon and after enjoying the picture, move on to the comments for some entertainment.
You fucked me, you all fucked me.

This does NOT have anything to do with the Doppler effect, idiots. The Doppler effect is sound. This is making a joke on redshift/blueshift. Look it up. Although I'm sure the hundreds of physicists who came out to comment today would be glad to enighten you.

Hahaha... who is the idiot exactly? Red/blue shift IS Doppler effect. Doppler effect is just the apparent change of ANY frequency due to differentials in velocity between the emitter and the observer. Do you make this much of an ass of yourself regularly? If so please leave alias for future entertainment.

Surely a joke as obvious as this doesn't need explaining. We all know what the Doppler effect is.

If you were travelling at .386c, then what color would the white part of the sticker become?

For those who asked how fast you'd have to be moving for this to work, I'd put in the ballpark of about .368c (about 246,000,000 miles per hour.) That was calculated using 475 nm as my blue wavelength and 650 nm as my red wavelength. Answers may vary if you use different wavelengths.

any uber nerd here want to calculate how fast you would have to go for the sticker to turn blue...

It works based on red shift, where light waves are compressed if you are moving towards the light source, or the ligth source is moving towards you at incredible speeds. White/red lght will shift to blue if you are moving towards the source, we see this with other galaxies, and can use ti to tell if they are moving towards or away from us. It helps prove the Big Bang Theory.

The sticker is playing on the Doppler Effect. Most commonly encountered with sound, such as emergency vehicles. If you are at a standstill, and an ambulance or other emergency vehicle is coming towards you, it will sound higher pitched because the frequency increases due to the velocity of the vehicle (at least, relative to you). When it passes and goes away, it sounds low pitched because the frequency is stretched out due to the vehicles velocity (in relation to you). The same applies for light, but the changes are unnoticeable at any achievable speed.

satanisthesavior (11/06/2009) [-] When an object that emits/reflects light moves towards another object, the light waves are compressed in a similar manner to how sound waves are compressed as a firetruck drives towards you. The sound of the firetruck has a higher pitch. Likewise, the pitch of the light that os being emmitted/reflected gets to a higher pitch the faster the objects travel against each other. When the 'pitch' gets high enough, the red light being reflected or emmited will be percieved as blue. This is known as blue shift. Likewise, the same objects moving away from each other will result in a lower 'pitch', progressing down into the reds and infrareds, known as red shift.

i don't know why people rated this comment down. it's a joke about the same exact phenomenon that the bumper stick joke is about. it's true: if you travel fast enough toward a green object, it would blue-shift and green would be one of the potential hues it would appear to be.
good one! :D
good one! :D
