Faster than light signalling
University of Washington physicist John Cramer is attempting to send a signal backward in time using the bizzare world of quantum mechanics.
He will use two photons which are “entangled” and thus doing something to one has an immediate affect on the other no matter where it is in time and space.

Entanglement theory caused Einstein to discount a lot of quantum mechanics and to search in vain for a better description of reality. He called the concept of entanglement “spooky action at a distance”.
All current experimental evidence supports particle entanglement, which according to John Cramer means that effect can sometimes come before cause and the only way to explain that paradox is that there must be some sort of reverse time signalling occuring between entangled particles.
John Cramer says that if his experiment works then signals will be recieved before he sends them.
“If the UW experiment succeeds at demonstrating faster-than-light communication and reverse causation, the implications are enormous. Besides altering our concept of time, the signaling finding alone would almost certainly revolutionize communication technologies.”
“A NASA engineer on Earth could put on goggles and steer a Mars rover in real time,” said Cramer, offering one example.”

Nice teaser, but a bit scant on detail. Creedence could have been added if you’d mentioned the technology he’s using in this attempt, and the content of the message (ie is it a data-state he’s sending or something more substantial).
