On the origin of the holographic principle

TL;DR

This paper explores how the holographic principle naturally emerges from the loss of information at causal horizons, linking quantum mechanics, gravity, and holography.

Contribution

It demonstrates that the holographic principle can be derived from information loss at causal horizons, providing a new perspective on its origin.

Findings

Holographic principle arises from information loss at horizons

Witten's prescription is derived from the formalism

Quantum mechanics and gravity emerge from information loss

Abstract

It was recently suggested that quantum mechanics and gravity are not fundamental but emerge from information loss at causal horizons. On the basis of the formalism the holographic principle is also shown to arise naturally from the loss of information about bulk fields observed by an outside observer. As an application, Witten's prescription is derived.
