Using math and physics, Ben Tippett, from University of British Columbia in Canada, has created a formula that describes a method for time travel. end-of China Cookie Depositing Machine Factory Tags: time travel, time machine, hg wells. "My model of a time machine uses the curved space-time to bend time into a circle for the passengers, not in a straight line. "While is it mathematically feasible, it is not yet possible to build a space-time machine because we need materials - which we call exotic matter - to bend space-time in these impossible ways, but they have yet to be discovered," he said. More than 100 years later, the LIGO Scientific Collaboration - an international team of physics institutes and research groups - announced the detection of gravitational waves generated by colliding black holes billions of lightyears away, confirming Einsteintheory. The four dimensions should be imagined simultaneously, where different directions are connected, as a space-time continuum.

"People think of time travel as something as fiction. That circle takes us back in time," he said. There is evidence showing the closer to a black hole we get, time moves slower," said Tippett. And we tend to think itnot possible because we don't actually do it.Using Einsteintheory, Tippett said that the curvature of space-time accounts for the curved orbits of the planets. "HG Wells popularised the term 'time machine' and he left people with the thought that an explorer would need a 'machine or special box' to actually accomplish time travel," Tippett said.The research was published in the journal Classical and Quantum Gravity. But, mathematically, it is possible," said Tippett.

While it is possible to describe this type of time travel using a mathematical equation, Tippett doubts that anyone will ever build a machine to make it work. "The time direction of the space-time surface also shows curvature.A US scientist has developed a mathematical model for a viable time machine - an advance that could bring stuff of popular science-fiction closer to reality. The division of space into three dimensions, with time in a separate dimension by itself, is incorrect, said Tippett. Ever since HG Wells published his book 'Time Machine' in 1885, people have been curious about time travel – and scientists have worked to solve or disprove the theory.In 1915, German scientist Albert Einstein announced his theory of general relativity, stating that gravitational fields are caused by distortions in the fabric of space and time. In "flat" space-time, planets and stars would move in straight lines. In the vicinity of a massive star, space-time geometry becomes curved and the straight trajectories of nearby planets will follow the curvature and bend around star
