## TL;DR

This paper proposes a mechanism to naturally explain the early universe's smoothness by weakening gravity in its initial moments, altering initial conditions and low entropy states.

## Contribution

It introduces a novel approach of weakening gravity at early times to account for the universe's smooth initial conditions.

## Key findings

- Weakening gravity leads to naturally smooth initial conditions.
- The mechanism alters the entropy landscape of the early universe.
- Potential implications for cosmological models and initial state assumptions.

## Abstract

CMB measurements reveal an unnaturally smooth early universe. We propose a mechanism to make this smoothness natural by weakening the strength of gravity at early times, and therefore altering which initial conditions have low entropy.
