One more point of similarity between Einstein's theory of relativity and Indian mythology

Einstein's theory of relativity states that if you travel at the speed of light, time moves at a different pace. So, if you leave earth at the speed of sound, and then return in an hour, many years would have passed on Earth. Here is a story from India mythology that illustrates the same concept. (This version is of the story is from Wikipedia).

Kakudmi's daughter Revati was so beautiful and so accomplished that when she reached a marriageable age, Kakudmi, thinking no one upon earth was worthy of her, went to the Creator himself, Lord Brahma, to seek his advice about a suitable husband for his daughter.

When they arrived, Brahma was listening to a musical performance by the Gandharvas, so they waited patiently until the performance was finished. Then, Kakudmi bowed humbly, made his request and presented his shortlist of candidates. Brahma laughed loudly, and explained that time runs differently on different planes of existence, and that during the short time they had waited in Brahma-loka to see him, 27 catur-yugas (a cycle of four yugas, totalling 108 yugas, or Ages of Man) had passed on earth (see time dilation theory). Brahma said to Kakudmi, "O King, all those whom you may have decided within the core of your heart to accept as your son-in-law have passed away in the course of time. Twenty-seven catur-yugas have already passed. Those upon whom you may have already decided are now gone, and so are their sons, grandsons and other descendants. You cannot even hear about their names.[2] You must therefore bestow this virgin gem (i.e. Revati) upon some other husband, for you are now alone, and your friends, your ministers, servants, wives, kinsmen, armies, and treasures, have long since been swept away by the hand of time."
