No one knows how to....
thats why it's still just a theory.

If you could fold time...you could time travel...and acording to this (if I understood it properly) skip from dimension to dimension, and skip from place to place in an instant.
One dimension would have infinitant posibilities,another dimension would have different infininate possibilities....

But they have only started time from the big bang....so it spans alot further than they make out...(again if I understood it properly???)

the whole folding thing was number 3 with the ant and the bending of the paper so the ant could skip from one side of the paper to the other in a split second...

lol im probably completly wrong
