The holographic principle is that the information content of all the matter that has fallen into a black hole can be represented by fluctuations in the surface of the event horizon. Extending this to the universe as a whole, the principle suggests that the two-dimensional (2-D) information on the outside surface of the universe, the cosmological boundary, encodes for the whole three-dimensional (3-D) content of the universe within.
However that is all a bit spooky and weird. Nor is it clear how such a mechanism might work physically. If it were true, it would mean we were all just puppets being controlled from the outside layer of the universe.
In this paper we provide a physical interpretation of the holographic principle. We start by developing an explanation for the vacuum, which is also not all that well understood. In turn that gives us some clues about the composition of void into which the universe expands. Interestingly, this theory predicts that the outside void is without time, and explains why. Of course it helps that we have separately developed a theory for how time works, which covers the whole range from subatomic particles, to atomic clocks, to mechanical clocks, to macroscopic bodies, and even to living creatures.
From this perspective the cosmological boundary is therefore the expanding surface where the fabric of the vacuum colonises the void beyond the universe. Thus the cosmological boundary is proposed to contain the discrete field elements of all the primal particules within the universe, and therefore contains information about the attributes of those particules at genesis. Inner shells then code for the changed locations of those particules and any new, or annihilated, particules.
So this theory supports the idea of an outer boundary or frontier for the expanding universe, and even predicts what is on either side of that boundary.
However it also predicts there is no practical way that anyone could sit at that frontier and control the whole universe. So the theory rejects the notion of holographic control of inner contents of the universe from the outer surface. (The details about this are in the paper, but basically concern the the infeasibility of placing a physical Agent at the boundary of the universe, and the useless of doing so in the first place). It also rejects the more fanciful holographic notions, e.g. that the boundary contains information about the future and past, or about all possible universes. The Cordus model suggests that there is no causality (control) from the boundary of the universe to its inner contents. The boundary is merely a historical snap-shot of what the universe was like at genesis.
So you can rest easy: the real you is not merely a flat 2D shape on the outer edge of the universe. According to this theory, there is no-one at the edge of the universe pulling the strings and making you dance.
