OK, I understand. Thanks.

This is really not far from the standard von Neumann interpretation

I think this ties in with my theory that "consciousness is randomness"

Perhaps the wormholes constitute a clock in some way?
Just daydreaming ;)

I think that this general concept is compatible with Hitoshi's theory, but
he realizes the evolution of histories by a different formalism, and he
the "jump leading to a moment of consciousness" as the classification of a
of quantum particles as a local system (center of mass, category)

In a discrete view your sheets become lattices, and we have multiple weakly

Different sets of links on the same set of nodes, perhaps?

if you could present a discretized version of the many sheeted theory it
would make it more clear to
everyone and might make correspondences with Hitoshi's and other theories
more clear --
just a pie-in-the-sky suggestion ;)

But it's all bits and bytes ultimately, Matti. Infinite dimensional math is
a shortcut for some purposes,
but also obscures things sometimes IMO. I say this as a mathematician who
spent many years studying
functional analysis etc.
