I can't claim this concept, but suddenly it makes sense for me.
I believe it was a concept of Randy Wayne White, writer of fiction around Sanabelle Island. Rogue Nuclear Physicist, theory of everything and such.

So then, the basic premise is what happens at a fathom above?
Basically everything for those of us who exist below six feet above the ground.

So why do we really care about all the star shit going on above our heads?

Why should I fire a fucking grid miles above me around the planet?

The planet is below me and within six feet of the surface.
Why should I give a shit about anything happening above that plane?

If you seriously consider interdimensional reality you will realize it is extremely localized.

So, technically, anything beyond about 20 feet makes absotively no fucking difference to our current reality.

So, bottom line, fuck the stars, concentrate on your own head space, that lump of fat three feet above you ass.

Oh, and BTW, if we all focus using that lump of fat in this one fathom of space, we could possibly destroy a paradigm and bring about a whole new world and all that fairy tale stuff.

wtf? Why don't we give it a try.

Beaming out from the other fathom next to the fathom that was.
