Welcome to the physics category
I just posted my first page, which is on quantum entanglement and the possibilities of sending signals back in time. This is based on an experiment that Dr. John Cramer started a few years ago, and when I met him at Norwescon in 2010, I dragged him to the bar, fed him a beer, and did my best to pick his brain. That plus research equals this. Make sure to have a bottle of aspirin handy when you read it.
