Karen Field reports that theoretical physicist Ronald Mallett is on a lifelong mission to build a time machine. His theory of a time machine, based on Einstein’s Theory of Relativity, involves creating a circulating beam of light and exploiting the energy to produce a gravitational field, at RF Designline:
Ronald Mallett, a professor of theoretical physics at the University of Connecticut, gave a mind-bending keynote speech on the physics of time travel to an enthralled audience at the Embedded Systems Conference here Tuesday morning, describing how black holes, blue giant stars, and worm holes (tunnels that connect the mouths of black holes)—some of the strangest things in the Universe—illustrate (at least in theory) the potential for time travel some day.
And that day, Mallett claimed, is not so far in the future as one might think.
“Time travel one of mankind’s oldest fantasies. But is it really possible? All of us have wondered what’s going to happen in the future, and we’ve contemplated the question, ‘What if I could back and change something in my past?” said Mallet.
