Time Travel

We all know after big bang which happened around more than 4.8 billions year ago, the universe started expanding from that very moment and new galaxies were formed. Everything changed after big bang. We had now periodicity for everything what we call as time. We know the time when big cloud was bursted. But our scientists are in serious confusion what was there before big bang. They are in dilemma and wants to know whether time itself has beginning or not? Frankly up till now know one know origin of time. We have specific period of everything. We have a particular time span of birth, death, sunrise,sunset, changing of seasons, harvesting of crops etc. Time ties us in string which covers full life cycle. But what if this time itself is a part of this string? What if this Time has time span too? Modern physics says time is not absolute, it is always relative which means in comparison. Great scientist Einstein concluded that since they measured the speed of light to be the same. in all frames of reference, but the distance the light traveled differed among watchers, moving at different speeds, and since distance is speed multiplied by time(D=S*T), so,  Einstein wrapped up to a conclusion that different viewer see time differently. Now what our ancient texts had said on this? In hindu mythology there is a story which was described in Mahabharata . Kakudami was a great king. his 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 musicians, so they waited patiently until the performance was finished. Then, Kakudmi bowed humbly, made his request and presented his shortlisted list of candidates for her daughter. 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, A cycle of four yugas, totalling 108 yugas, had passed on earth. This story clears that our ancient people know about the modern concept of time. Even in bible and many others religious books we have traces of time travel. So to know the modern concepts of time there is nothing bad in consulting our old text books. May be then we get to know about the things which are still to be revealed...
