Time travel subtly intertwines with our measurement of time through clocks and calendars – artificial constructs we’ve put up. But how do we know time exists? How can we say for sure that time is passing by? Say, it did actually exist. When did the Universe\u2019s clocks start ticking? It is generally accepted that the concept of time came into existence after the Big Bang. But who put the batteries in that clock? <\/p>\n\n\n\n
Time has continued to confound physicists and philosophers for centures. Oxford defines time as an indefinite, continued, progress of existence and events in the past, present and future, regarded as the whole. And we\u2019ll take their word for it. What about time travel, though? What if you could go back in time and change your past? Or what if you could travel hundreds of years into the future and meet your great-great-great-something grandchildren? How exciting would that be?<\/p>\n\n\n\n
Early stories of time travel feature a character goes away or sleeps for some time, only to be reawakened in a future society. The idea of time travel first appeared in the Hindu Text, the Mahabharata<\/em>, in the 9th<\/sup> century BC. The Mahabharata mentions the story of a King called Raivata Kakudmi<\/em>, who travels to heaven in order to meet the Ultimate Creator Brahma. When he returns to Earth, he is shocked to have learnt that many years have passed. The Japanese tale of Urashima Taro<\/em> is one of a fisherman who visits an undersea palace, and on returning home, realises that 300 years have passed.<\/p>\n\n\n
