The "observer problem" affects areas of knowledge which you, as an atheist, evidently reject on principle that your "reality" is only that which is physical.

Well, lets take your Many Worlds theory. Do you really believe that an infinite number of universes are coming into existence every moment?

Or do you believe the more plausible theory that wave functions collapse?

The many-worlds theory is Everett's, not mine. It is a bizarre consequence of quantum decoherence.

As Penrose noted (paraphrased) we need a new kind of physics, like quantum mechanics, Newtonian physics and Relativity - something that translates between them.

Meanwhile, I keep an open mind to geometric physics and theories of relativity and cosmology (Wesson, Vafa, Fineman, Tegmark et al).

In my view Everett's theory is nearly as untestable as last Thursday-ism, that "all that there is" was created last Thursday.

My bias on such theories would be that of Einstein's, i.e. his dream to transmute the base wood of matter to the pure marble of geometry.
