Regulating Eternal Inflation

TL;DR

This paper proposes a new interpretation of eternal inflation, suggesting that the physics can be understood as a quantum system with finite states, challenging traditional views.

Contribution

It introduces a novel perspective on eternal inflation, framing it as a finite quantum system, which may alter the conventional understanding of such space-times.

Findings

Reinterprets eternal inflation in terms of quantum mechanics.

Challenges the conventional picture of eternal inflation.

Suggests finite state quantum systems can model bubble nucleation.

Abstract

We present an interpretation of the physics of space-times undergoing eternal inflation by repeated nucleation of bubbles. In many cases the physics can be interpreted in terms of the quantum mechanics of a system with a finite number of states. If this interpretation is correct, the conventional picture of these space-times is misleading.
