How time travel could work: Scientists have uncovered a way to send messages into the past Time machines may seem better suited to science fiction than the physics lab, but experts say this futuristic technology could become a reality. Researchers have revealed how time travel could really work by using the laws of quantum physics. While their method won't let you hop back to the time of the dinosaurs, scientists say it could be possible to send messages into the past. The researchers even say this mind–bending technique would work just like in Christopher Nolan's sci–fi epic, Interstellar. In the...
