Aren't you just rehashing Morphic Field?

I don't know enough about Rupert Sheldrake's morphic field hypothesis. I've got him on my reading list. But as for what you ask, I suspect that you're right, at least in part or degree.

I believe that I'm dabbling in a 'filled out' morphic field concept. Where Sheldrake envisages a field that connects everything that exists at-the-same-time, my construct is not so much a field (which makes you think of a two-dimensional area (well, it does a non-scientist)) as a volume or space.

In a nutshell, then, I'm toying with the idea of everything at everytime being linked.
