Holographic Principle
The idea that the information within a volume of space, such as a black hole, can be entirely encoded on its two-dimensional boundary, like a hologram.
Videos Mentioning Holographic Principle
Leonard Susskind on Richard Feynman, the Holographic Principle, and Unanswered Questions in Physics
Y Combinator
A principle suggesting that the description of a volume of space can be encoded on a lower-dimensional boundary. Susskind explains its connection to black holes and information, and its eventual mainstream acceptance as a tool in physics.

The idea that all the information contained within a volume of spacetime can be stored on its boundary, as seen with black holes where information is encoded on the event horizon's area.

The String Theory Wars and What Happened Next
Sabine Hossenfelder
The idea that a higher-dimensional space (like AdS) can be described by a lower-dimensional theory (like CFT), analogous to a hologram.
