I personally believe thats not possible
See, time is a dimension which we can in no way control, The 2nd or 3rd law of thermodynamics, I think rpkash will know is, the entropy of the universe always increases! That is heat is always released, a cold coffee can never get hot. How is this related?
Well, thats how time is, if you did 'move' the 4th dimension (time) then you would be disturbing the 3rd dimension space in the past. Which is clearly not possible. It might lead to the Chaos theory, you know the butterfly effect!
Please rpkash, I think you know what I am talking, if not look it up and explain, Im getting wrinkles in my brain!
