Wormholes--Photons Arriving Before Being Sent
I was just watching a show on String Theory on PBS and recalled an interesting experiment a few years back. I can't find anything about the experiment, so maybe someone can point me to a source where I can read more about it (or give me names of those who worked on experiment so I can search for it).
A few years ago, some physicists were shooting photons through a block of lead and discovered that, of the few photons that made it through the other side of the block, some of them had exited the block of lead before they were shot into the front of the block of lead. That is, some of the photons arrived before they had ever left!
Does anyone know what I'm talking about? I'd like to read more about this because it was theorizied that these photons may have found a wormhole that enabled them to exit the block before they had ever entered it.
Thanks for your help.
