I don't know MOP, perhaps I've inadvertantly wandered into a realm here that is not what my first impression of it was.
After reading the home page and then several of the posted messages I thought I was in for some hard scientific dialog on the concept of time travel.
It seems the longer I linger here, the more I get the impression that the devotees of this site are more into exploring the etherial, esoteric and spiritual aspects of the subject, which to me is not really time travel at all.
I'm not trying to belittle anything or in any way discount anyone's beliefs, but I'm more into the hard science of things and perhaps this is not the forum for me.
The site you list above as a recommendation is just not my idea of what discussions about time travel are. The site has its place to be sure, it just isn't in the realm of what I call science.
For now, I'm looking for something a bit more concrete. Hard core if you will. My Idea of scientific theory is that it needs to be falsifiable in some manner. These discussions of multiversity as they apply to the concept of ever manifesting timelines based on our beliefs is in the realm of the spiritual or paranormal. They are not falsifiable in any way. By their very nature, they can only EVER be speculative.
That you for your hospitality and the time spent reading my ramblings.
