“That means light is traveling infinitely fast. “This does not mean the energy velocity of light passing through this material goes to infinity, or faster than the speed of light through air,” Yang told us. “It’s only the phase velocity of light that reaches infinity.”

How to Make Light Go Faster?....
Headers, Ported and polished heads and fuel injection with a supercharger.......
Why would you want to make it faster. In my opinion, it already goes too darn fast as it is.
My old school.....back when it was UMR.
This has been done for years. Phase front (1/group delay) going faster than the speed of light does not violate General or Special Relativity, because it is just a statistical construct, not a real thing, going faster than light.
combine eggheads with grant money, mix well.
yields a bunch of jibba jabber with no practical use.
fail.
OK, say I'm a photon. I'm moving at the speed of light. For me, clocks do not move. I go from A to B in zero time, at least zero photon time. That's pretty fast. Actually that's infinitely fast.
And what do I care about your stinkin' "phase velocity"? I'm a particle. I just don't have any mass. You can't hold that against me.
I been pondering this for awhile myself .. I keep trying to hop under the blanket and beat the light, not much luck so far, bungy cords, superball propulsion rods, nope, my head is already in a vacuum,, forget that route. How anybody gets around this multiverse of ours during rush hour in the south bay is beyond me. :-]
Go ahead.. Grease that lightnin’!
What is “phase velocity of light?”
