UW professor aims to make time travel a reality -- receiving a message milliseconds before it is sent!

Physicists, mathematicians, philosophers and that guy talking to himself on a street corner all have opinions about validity of time travel.

So does Dr. John Cramer, professor Emeritus of Physics at the University of Washington. He wants to make it a reality.

But Cramer's form of time travel is not the teleportation characterized by Hollywood and science fiction. As time travel goes, Cramer thinks in baby steps. He's working on the possibility receiving a message milliseconds before it's sent.

"I have to admit, this is pushing the envelope and often the envelop pushes back," says Cramer, a nuclear physicist who has worked on projects involving the Large Hadron Collider in Switzerland.
