Whats the speed of dark ?

[GrauGeist]

Black-out, mayhap?

Dunno...I haven't been en-light-ened yet...

 

[BikerBabe]

Dunno...I haven't been en-light-ened yet...

Oh - the light hasn't yet been switched on? Nothing new in that...*runs like he££*

 

[RabidAlien]

Ouch....that shot in the dark turned out to be a low (light) blow!

bikerbabe, while you are not actually measuring the speed of the void you can measure the decrease of the voidness of the glass. it's just the inverse of the fill speed. add one photon to a cubic meter of space and it is no longer a total void. thus the speed of dark is the same as the speed of light in the medium in question

Somehow, I've get the feeling that you all are trying to keep me in the dark here....

 

[Aaron Brooks Wolters]

Lucky, I really don't think you need us for that. Sorry, I'll go back to my little corner now.

 

[Geedee]

I've typed this bit in white font...to help you see it !

Dark, per se, is a human perception indicating the absence of acceptible energy photons striking the retinal cones and initiating chemical reactions therein. infra-red photons and or ultra-violet photons have too little and too much energy to initiate these reactions and are perceived as darkness by humans. red, green, and blue photons not entering the eye are also perceived as dark, as in a laser beam viewed laterally. even intergalactic space is filled with EM radiation and not dark except to human senses

Absolutely !..an iluminating comment ......and I promise not to write in white font again !

Interesting comments there...so would for instance, you percieve 'dark' differently from me ...for example ...as dark would appear to rely on the state of ones eyes (rods / cones ...from what I can remember form school all those years ago !) to percieve ?

But is that glass half full or half empty?

What came first the hen or the egg?

 

[RabidAlien]

Was it a dark hen or a light hen?

 

[Wayne Little]

What came first the hen or the egg?

Wasn't the answer to this, global news the other day.......?

 

[BikerBabe]

What came first the hen or the egg?

The egg.
Dinosaurs laid eggs, the hen evolved later from the dinos.
That oughta answer that age-old question.
Personally, I think it was a dark egg, laid by a hippocroccofrog.

 

[Vic Balshaw]

So the Hippocroccofrog came first.................

 

[Wayne Little]

Ah... Now I get it..... No I don't.......I'm still in the dark... I think?

 

[mikewint]

GeeDee, yes you would, as in individuals whom are color "blind". if your red cones were nonfunctional you would percieve a room lit by red light as being "dark". the same principle as infra-red sniper scopes which "see" in the "dark". dark which is actually lit by nonperceived photons in the infra-red spectrum

Check this out, guys!

So...as Terry asked, this doesn't differentiate between African or European dark !. So we are no nearer or farer to getting to the bottom of this...and No, I have no idea dark actually has a bottom !
