Since every entrant leaves behind a signature rearrangement, or supertranslation, of the light,
the hologram encodes all the stuff inside the black hole.

A real artist creates a kind of ideological
hologram, I think: what you see depends upon the angle you are observing from... but the entire message (sometimes many thousands of words, potentially) is
encoded in each part of the work.
The
hologram operates with circularly polarized light, and the information is
encoded on to the light beam by the varied angles of the skyscrapers.
The idea is similar to that of ordinary
holograms where a three - dimensional image is
encoded in a two - dimensional surface, such as in the
hologram on a credit card.
Even more information can be
encoded in the
hologram by designing and arranging the nanofins to respond differently to the chirality of the polarized incident light.
Holograms are three - dimensional images
encoded in two - dimensional surfaces.
Holograms, like digital photographs, capture a field of light around an object and
encode it on a chip.
This
hologram is one of two different holographic images
encoded in a metasurface that can be unlocked separately with differently polarized light (Image courtesy of The Capasso Lab / Harvard SEAS)
