We noted last week the possibility that our entire universe may just be a low-res 3D rendering of the real 2D universe, which exists out on the boundary of what we normally think of us "the universe." The hologram that we live in is extremely coarse compared to the boundary universe -- our "pixels" are 19 orders of magnitude greater than those used in the real universe.

I'm thinking that the real universe needs higher resolution in order to contain the same structures that our universe does, only in two dimensions rather than three. But surely four or five orders of magnitude would take care of that? That still puts the boundary universe at a resolution 15 orders of magnitude higher than what's possible here.

So the boundary universe is potentially encoded at a level of detail 1,000,000,000,000,000 times greater than our universe. This raises some questions.

-- What is the boundary universe doing with all that information? Is it keeping better track of things than we are in this universe? Is information about the past available in more detailed form there?

-- Are we just a projection of the boundary universe, or are we what's going on in there? I mean -- is what's happening in there just a two-dimensional version of a guy at a keyboard, is there some kind of uberPhil in the boundary universe writing a blog post that is 15 orders of magnitude more sophisticated than this one?

-- If this (highly improbable) picture of the universe were to turn out to be true, should all metaphysical and cosmological speculations (including the ones I'm making right now) be tabled until we understand the boundary universe better?

Anyhow, that's what goes on in my head up here in the big, grainy, blurry holographic construct that we call the universe.
