Entropic Dynamics

TL;DR

This paper proposes that the laws of physics can be viewed as laws of inference derived from the principle of maximum entropy, leading to a form of entropic dynamics that resembles general relativity.

Contribution

It introduces a novel approach where physical laws emerge from inference principles, specifically maximum entropy, rather than traditional physical axioms.

Findings

Derives a dynamics framework from inference rules

Shows formal similarities with general relativity

Suggests physics as an inference process

Abstract

I explore the possibility that the laws of physics might be laws of inference rather than laws of nature. What sort of dynamics can one derive from well-established rules of inference? Specifically, I ask: Given relevant information codified in the initial and the final states, what trajectory is the system expected to follow? The answer follows from a principle of inference, the principle of maximum entropy, and not from a principle of physics. The entropic dynamics derived this way exhibits some remarkable formal similarities with other generally covariant theories such as general relativity.
