WORMHOLE AND TIME-TRAVEL

ABSTRACT:
Things don’t happen in reverse? Why?
Sounds absurd - but why? Why, exactly, it is impossible to unbreak an egg? Why can’t we unmelt an ice? Similarly, why can’t we unburn the matches and unsprain the ankles? Why can’t we mix up yesterday and tomorrow? We only get older, not younger. Trees only get taller, they don’t return to acorns. Our sun only ever uses up its fuel, never returning to a cool ball of hydrogen. Time only goes in one direction but why is it impossible for us to reverse the clocks?
CONTEXT:
Like many of the stories about physics, this one starts with Isaac Newton. Newton’s laws are astonishingly successful at describing the world. They explain why apples fall from tree and why the Earth orbits the Sun. But they have an odd feature: they work just as well backwards as forwards. If an egg can break, then Newton’s law says it can unbreak.
It sounds like a simple question but to answer it, we need a deep study. Some scientist even say travelling to the past is impossible. In physics, time is described as a dimension much like length, breadth, and height. When you travel from your house to the school, you’re travelling through a direction in space, making headway in all the spatial dimensions- length, breadth and …show more content…

The first problem is size. Primeval wormholes are predicted to exist on microscopic levels, at about 10Centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes. Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly. But some research found that a wormhole containing “exotic” matter could stay open and unchanging for longer periods of
