I have identified the factor that controls movement from the past to the present. It has occurred naturally, and can be duplicated electronically, and reversed. The future is an abstract concept, and does not exist beyond the here-and-now. This is not the fantasy of quantum physics, and it is certainly not occult nonsense. I can put you in Gettysburg, PA, in 1863, but it won't be cheap.
Aside from the ability to retroactively correct past mistakes, imagine the economic opportunities.
