Ronald Mallett, a professor at the University of Connecticut, USA has used Einstein’s equations to design a Time Machine with circulating laser beams.
According to professor Ronald Mallett the Time Machine could be ready for test with in next 10 years.
Time travel stories have been a staple of the science fiction stories and movies from a long time. We have a number of movies such as Terminator, 12 Monkeys, Army of Darkness, Planet of the Apes and lots of other movies. But no one ever thinks seriously about the possibility of Traveling in past or future.

Ronald Mallett is teaching Physics in University of Connecticut from 30 years. He considered an alternative to these time travel methods based on Einstein’s famous relativity equation: E=mc2.
According to Mallet, Einstein showed that mass and energy are the same thing and time travel is theoretically possible. Mallett has published his first research on time travel in year 2000 in Physics Letters.

‘The time machine we’ve designed uses light in the form of circulating lasers to warp or loop time instead of using massive objects.’

Mallett is designing a desktop-sized device that will test his time-warping theory. Some subatomic particles have extremely short lifetimes and by arranging mirrors, he could be able to make a circulating light beam, which should warp surrounding space. He says that he will observe the existing of these particles for a longer time when placed in the vicinity of the circulating light beam because .A longer lifetime means that the particles must have flowed through a time loop into the future.
Mallett explained to PhysOrg.com. That empty space is like coffee and the spoon is like the circulating light beam. When you stir the coffee with the spoon, the coffee or the empty space gets twisted. Suppose you drop a sugar cube in the coffee. If empty space were twisting, you’d be able to detect it by observing a subatomic particle moving around in the space.’
