Svetlost putuje unazad... i brze od - svetlosti
Potpuno nebulozno zvuci, a kad krenete da citate o eksperimentu koji je izveo profesor optike sa Univerziteta Rocester, Robert Bojd, tek vam onda nista nece biti jasno... Ne brinite, nije jasno ni mnogim naucnicima...

Uglavnom, izveden je eksperiment cije sheme i cak i animaciju mozete videti na linku datom dole - svetlosni impuls pusten je na barijeru od oprickih vlakana, koja je generisala kontra impuls cak i pre nego sto je inicijalni impuls dodirnuo barijeru. Taj kontra impuls je generisao novi impuls na kraju barijere, proputovao kroz barijeru nazad i ponistio inicijalni impuls...

Tako sam bar ja skapirao... :?

Uostalom citajte i pokusajte da razumete:

Light Travels Backward and Faster than Light

It sounds nuts, but a scientist says his team has made light go backward. And this is not a simple trick of mirrors.

Previous work has slowed light to a crawl. But in the new research, a pulse of light is given a negative speed and—as if just to make your head spin—the researcher says the experiment made light appear to exceed its theoretical speed limit.

If you totally confused, don't worry. This reporter doesn't get it either. Nor do a lot of really smart scientists.

"I've had some of the world's experts scratching their heads over this one," says Robert Boyd, a professor of optics at the University of Rochester. "It's weird stuff."
