Want to debunk? - The speed of darkness is faster...
Discussion
There is a video up on gizmodo by Michael Stevens where he makes a whole bunch of claims around the speed of light. Mostly he is using illusions to draw false conclusions. The sad thing is that it seems people are falling for this bunk. This makes me angry and a bit sad.
Why is the speed of darkness faster than the speed of light?

There is - they got back together in 2011

Did you watch the whole film? He seemed to do a good job of introducing ideas for things that seem to move faster than light and showing why they were not actually doing soWhy is the speed of darkness faster than the speed of light?

Seen a few vids on youtube regarding this and the question is attempting to 'prove a negative' as such.
Darkness is just the absence of light and does not possess any 'speed' qualities as there are no 'physical entities' so to speak.
The usual experiment shown is with a lazer light shone at the moon from earth. If this lazer light were say 200mm in diameter and one were to pass your finger over the front of the emission and watch as the 'shadow' of your finger 'goes' across the moon, the shadow will 'appear' to travel faster than light speed.
Although it is not the darkness that is 'travelling' across the moon, it is the absence of light emitted from earth at the point where your finger is blocking it that is giving rise to the illusion that the shadow is 'travelling'.

I thought Einstien disagreed - time would slow down slightly?eldar said:

Only if it were 'information' that were travelling.No 'information' is moving with a 'shadow' , it is simply the lack of information being received by any static point on the moon at a given time.
Similar to a line of LEDs turning on or off in sequence. Each LED is stationary, but the light emitted from each is not in 'motion' relative to the path of the on-off sequence... just that our brains turn this in to an illusion of movement.
The other experiment that often gets used is by not using a 'shadow' but instead a person sat on earth uses a strong lazer beam and rotates the angle of the source so that the beam 'scans' across the diameter of the moon.
Again if done fast enough it would seem the reflection of the beam across the moon surface travels faster then light.
But again, a reflection from a stationary point on the moon is not 'something' travelling in the same direction as the 'scan'...if it were the light that was transmitted to the moon itself, then you would not see the reflection, it would be travelling along the circumference of the moon in the direction of the 'scan'.

Yeah, that's the sausage! 
I should have noticed the mis-spelling, I often write up posts in word before copy&paste in to the web browser... I'm now off to kill my spell-checker as to why it never picked up "lazer" !!

Agreed, I'd thought, wrongly, that you were saying light could travel faster than light...No 'information' is moving with a 'shadow' , it is simply the lack of information being received by any static point on the moon at a given time.

Your brain's failure to pick up "lazer" is slightly more worrying.I should have noticed the mis-spelling, I often write up posts in word before copy&paste in to the web browser... I'm now off to kill my spell-checker as to why it never picked up "lazer" !!

How do you explain dark suckers then?
