Extract: Astrophysicist Ron Mallett believes he’s found a way to travel back in time — theoretically. The tenured University of Connecticut physics professor recently told CNN that he’s written a scientific equation that could serve as the foundation for an actual time machine. He’s even built a prototype device to illustrate a key component of his theory — though Mallett’s peers remain unconvinced that his time machine will ever come to fruition.
