And keep in mind that no one - not even Stephen Hawking - is sure what happens when you cross over the singularity of a black hole.

If we, eventually, are able to harness these natural forces in this regard - as they've been around for quite some time - the range of their use would perhaps allow us to travel back before now.

That was my only point, whelp.
