Einstein must be spinning like a top (all except his brain which wasn't buried with him).
Read the source article, this extract does not do it justice......

"
""In this way, one can argue that that the wave packet travels with velocities much higher than the velocities of light,"All this means is that the shape of the wave changed. The velocity of energy propagaiton in any material is always less than c. Here they are simply talking about phase velocities which are related to wave shape, not energy propagation.

I would suspect they are just observing some lesser understood quantum mechanic, and mis-characterizing it.
I never was totally comfortable with the whole "Light is both a wave and a particle" explanation. Seemed like a similar cop-out to the whole dark matter idea when calculating the mass of the universe, or the entire understanding of 'strong' and 'weak' nuclear forces.

An elite subset of the Evolution list. See the list's explanation at my freeper homepage. Then FReepmail to be added or dropped. |

I did, the only thing I see is the "superlens" that will allow looking into a cell. And they admit that the "superlens" is a long way off.
My original question stands.

It's a little misleading to confuse the phase velocity with the velocity of light, though it's hard to explain the difference to someone who has not been formally trained in physics.

Of what importance is your original question? What is so special about seven years?

"the ability of negatively refracted light to seemingly defy Einstein's theory of relativity and move backwards faster than the speed of light."That's nothing. I had some stocks recently that moved backwards faster than the speed of light.
To: Brilliant
The phase velocity of a wave is the rate at which the phase of the wave propagates in space. This is the velocity at which the phase of any one frequency component of the wave will propagate. You could pick one particular phase of the wave (for example the crest) and it would appear to travel at the phase velocity. The phase velocity is given in terms of the wave's frequency and wave vector k by
v_\mathrm{p} = \frac{\omega}{k}
Note that the phase velocity is not necessarily the same as the group velocity of the wave, which is the rate that changes in amplitude (known as the envelope of the wave) will propagate.
The phase velocity of electromagnetic radiation may under certain circumstances exceed the speed of light in a vacuum, but this does not indicate any superluminal information or energy

What is so special about seven years?Because that's about the amount of time, IMO, that the comman man will wait for a revolutionary development, in even a trial environment.
After that it's forgotten about and loses funding.

Reminds me of...
Prosecutor: "Did you check for breathing?"
Defendant: "No."
P: "Did you check his pulse?"
D: "No."
P: "Did you, in fact, do ANYTHING to confirm whether the victim was, in fact, deceased?"
D: "No."
P: "Then how could you know he was, in fact, deceased?"
D: "His brain was sitting in a jar on my desk."
To: FreedomNeocon
Yeah, I understand that, but what kind of an analogy can you come up with that the average guy would understand?
