 * 1) We know that the speed of light is the fastest speed in Universe No one can travel faster than light
 * 2) According to Stephen Hawking Time travel is Possible but if we can go in the past and does some changes in past then there is two time line created
 * 3) like if a person go in past and kill her grand father,then you imagine that if her grandfather was dead then can possible Your father and you born
 * 4)  First time line has no change in which we live
 * 5) second time line will created in     multiverse
 * 6) we know that the distance between on Universe is many light years far
 * 7) so we imagine that if we can do time travel than we can travel faster than light
