Default Fast light

Read a piece today that claimed within a nano-structure light traveled instantaneously. The claim was that because it was not in a vacuum it did not violate Einstein. I did not understand most of it. I will try and remember to get more details tomorrow. (what lab etc)

I vaguely recall reading somewhere that electron tunnelling also happens instantaneously.

Isn't that because the electrons push each other?

"A European research project has demonstrated field effect transistors in which the gate (channel) is controlled via quantum tunnelling rather than by thermal injection, reducing gate voltage from ~1 volt to 0.2 volts and reducing power consumption by up to 100x. If these transistors can be scaled up into VLSI chips, they will significantly improve the performance per power of integrated circuits."

Interesting.
Quantum tunnelling - Wikipedia, the free encyclopedia

Edit:
Almost tempted to buy that article, €30 sounds a bit much for a peek though :-P

Einstein said he was wrong.

Quote:
Special relativity was the result of 10 years of intellectual struggle, yet Einstein had convinced himself it was wrong within two years of publishing it. He rejected his theory, even before most physicists had come to accept it, for reasons that only he cared about. For another 10 years, as the world of physics slowly absorbed special relativity, Einstein pursued a lonely path away from it.

More and more I am convinced that Einstein was an Alien or Alien human hybrid and not a pure Human being.

Either that or a time traveller from the future who saw that WW2 needed to be won so he came back and let the USA win.
