So if Time is relative then it could not be achieved every time accurate and when there will be some mistakes the time will lead us to travel in other dimension
Yes. By increasing speed upto the speed of light
No, time travelling isn\’t possible becz if we have to go in past or in future we have to rearrange the whole universe which is not possible to human, it is another fact by Einstein that if we travel at light speed the our time get slow but universe is in normal so when we stop we are in future but that is not time travelling we lose the past for future we get in future but we never return to past. ..so, over all its simple time travelling isn\’t possible
This was proved by Einstein by in the laws of Relativity
According to Einstein time is relative but not absolute
