The World As Hologram
Our existence could be coded in a finite bandwidth, like a live ultra-high-definition 3-D video. And the third dimension we know and love could be no more than a holographic projection of a 2-D surface.
According to ‘t Hooft, the combination of quantum mechanics and gravity requires the three dimensional world to be an image of data that can be stored on a two dimensional projection much like a holographic image.
The two dimensional description only requires one discrete degree of freedom per Planck area and yet it is rich enough to describe all three dimensional phenomena.
