I still don't understand one thing. If you travel back in time there would be two of yourself. Is that correct? Or is it that if you travel back in time, you will see the same people as the future, the same age and everything, but back 50 years or so. Or will you go back 50 years from when you turn back the clock.
How would it work?

What exactly is 'Same Position'? Everything in the Universe is in motion so while it may be Planted in one spot for it's entire life, it also happens to be spinning through the cosmos at some incredible speed, riding upon this big ball we call earth. So each 'Reference Frame' throughout all life on this planet as well as others would be unique at each and ever moment. It may only seem that something is 'Still' within Space or Time for that matter, because of the lack of perception at that moment.
