Speed of light exceeded? CERN think it may be...

There is no such thing as 'dark', it is simply the absence of light.

Your not a discworld fan are you?

I belive that's a book by Terry Pratchett... nope, never read it. But light is energy, ie a tangible something that be switched on and off and measured; darkness is not. Close a box and it's dark inside; it doesn't need any input to sustain that darkness.

I thought the spin coupled pairs effect was debunked not long ago? What it amounts to is that it is still impossible to send information faster than the speed of light by this effect, and so doesn't contravene any physical laws. The error measured in the neutrino experiment is the equivalent of 18 metres, not massively greater than the speed of light, so it will be interesting to see where any errors are found to be hiding.

Are you saying quantum entanglement has been debunked recently or that it cannot be used to convey information faster than the speed of light ?

Hopefully the latter, as entanglement is still wonderfully baffling to me ....................and my White rabbit friend Harvey

Your of course correct in all that. Its just on of his mad theories that make the books so good.

So light is actually darkness, but lit up!
