Answer 1

As Sir Albert Einstein said,
if you move or travel with a speed of light that is 3,00,000 kilometres per second then the distance will be shorter for you (length contraction) and time will also slow for you (time Paradox and time dilation).
but what will happen if you move with more than the speed of light.
It means that the time will go in negative that means you will be able to go in past.
but it is not real,
first is that, you cannot attain a speed of light.
and second that, going in past is virtual for you and for me also.
