What is the speed of dark?

[sillysally]

So there exists a speed of light but how come I never heard of the speed of dark?

Isn't dark faster than light since it came first? Or did it? Which came first light or dark?

[mkirkpatrick]

Great thought SS,the speed of dark is absolute,while light is resolute?

Sal .... You could be on to something ... LOL

When we observe the light spectrum of a distant galaxy or cluster the colour ranges from Red, Yellow, Green, Blue. Purple, Indigo, Violet (I think)

Across this rainbow spectrum, dark lines are visible. These, shaped like a barcode, are actually the absence of light, the absorption lines. The distant object, emitting light across the whole spectrum did not emit any light in these absorption areas.

The absorption lines tell us a huge amount about the object emitting the visible light. This absence of light is instantly available, as you say, because nothing has to cross between the object and us. Zero time.

Infortunately they are not visible, tho still there, until the emitted light reaches us at the speed of 'c', and so enables us to contrast the absorption lines on the rainbow background.

Sal ... I hope this makes sense ... LOL

You were the inspiration behind this thought Graybeard, you get extra credit for this thread. What you say makes sense, although I never heard of those dark lines before, I am surprised to hear they are there.

Now, for the speed of light believers, go Planck off!

Sal ... from these little lines Scientist can tell exactly what each star, galaxy or cluster or nebulae is made of.

The reason is that the elements the object is made of, absorb the light that is theirs and let the rest emit.

Therefore the dark barcodes (the missing light) tell us exactly what the object is made of.


A truly 'something for nothing' at faster than light speed. The speed of DARK

Cool Austin ... I had to google that one. Wadda isit dat everybody is speakin da Latin lately ...

LoL! A lot of our language already is Latin. Psycho maximus.

You bring up a really good point Sally. During the spatial inflation, space was moving a whole lot faster than light. As Greg pointed out those dark bands don't represent movement, rather absorbtion.

Best,

Pat

Hold up, are saying that dark isn't a movement yet pre light space moved faster? If light doesn't play a part in the area of space, why do we use it as a universal measurement?
