I Measurements at the Cosmological Horizon?

  1. Jul 15, 2017 #1
    Under the holographic principle, the physical description of the 3d world at a particular location in spacetime is encoded on the two dimensional cosmological horizon that encapsulates it.

    Does that imply that the "measurements" taking place on a 2d shell that is the horizon is creating new information on that shell, which maps to the observed increasing entropy within the corresponding enclosed 3d section of universe?

    What is this "measurement"? Is it just the interaction of bits of quantum information, analogous to decoherence in regular quantum mechanics?

    Also, does this have any relation to dark energy? The amount of entropy( i.e information) is proportional to the area of a horizon. Increased information means increased surface area, which means the volume enclosed becomes larger. Since spacial volume itself is inflating due to dark energy, it's natural to see the potential for some sort of connection here.
