Universe regions have information. Total is 10^60 bits. Universe regions have boundary surfaces, such as sphere around galaxy dark matter or event-horizon around black holes. For outside observers, all region information flows through boundary surface to observer, so boundary surface holds region information, though surface has lower dimension than region. If observer is far away, bounding-surface physics can represent region physics {holographic principle}. Perhaps, region physics projects onto boundary surface, and boundaries are like holograms {strong holographic principle}. Perhaps, region information projects onto boundary surface, and bounding surface has information channels {weak holographic principle}.
hologram
Just as surfaces can hold holograms, from which coherent light can make three-dimensional images, two-dimensional surface boundaries can contain all information needed to describe three-dimensional space regions. For example, superstring theory for anti-de-Sitter space-time five-dimensional regions is equivalent to conformal quantum-field theory of four-dimensional surface-boundary-point particles.
string theory
Hyperbolic-space regions have constant surface boundary. In string theory, boundary-surface gluon strings represent one quantum information bit and have thickness and strong-force color. String thickness represents space-point distance from boundary surface. Color represents information about space-point's quantum state. String number varies directly with space-region radius, so larger radius makes large boundary surface. Surface-string interactions represent gravitons.
