SCI FI of today becomes science of tomorrow
"Einstein once said "The relativistic analogy can be carried to its logical end. Since time begins to slow down with higher speeds,it can be shown that at the speed of light it stops totally and beyond that begins to run backwards! Similarly, matter having contracted more and more, ultimately vanishes. But Beyond the spped of light it is difficult to imagine negative matter with infinite mass.
Einstein was probably right when he said that the speed of light was the upper limiting velocity in the universe."

Professor Predicts Human Time Travel This Century
With a brilliant idea and equations based on Einstein’s relativity theories, Ronald Mallett from the University of Connecticut has devised an experiment to observe a time traveling neutron in a circulating light beam. While his team still needs funding for the project, Mallett calculates that the possibility of time travel using this method could be verified within a decade.
Black holes, wormholes, and cosmic strings – each of these phenomena has been proposed as a method for time travel, but none seem feasible, for (at least) one major reason. Although theoretically they could distort space-time, they all require an unthinkably gigantic amount of mass.
Mallett, a U Conn Physics Professor for 30 years, considered an alternative to these time travel methods based on Einstein’s famous relativity equation: E=mc2.
“Einstein showed that mass and energy are the same thing,” said Mallett, who published his first research on time travel in 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.”
To determine if time loops exist, Mallett is designing a desktop-sized device that will test his time-warping theory. By arranging mirrors, Mallett can make a circulating light beam which should warp surrounding space. Because some subatomic particles have extremely short lifetimes, Mallett hopes that he will observe these particles to exist for a longer time than expected when placed in the vicinity of the circulating light beam. A longer lifetime means that the particles must have flowed through a time loop into the future.
“Say you have a cup of coffee and a spoon,” Mallett explained to PhysOrg.com. “The coffee is empty space, and the spoon is 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.”
And according to Einstein, whenever you do something to space, you also affect time. Twisting space causes time to be twisted, meaning you could theoretically walk through time as you walk through space.
“As physicists, our experiments deal with subatomic particles,” said Mallett. “How soon humans will be able to time travel depends largely on the success of these experiments, which will take the better part of a decade. And depending on breakthroughs, technology, and funding, I believe that human time travel could happen this century.”
