How does the Universe expand?

TL;DR

This paper explores how the fundamental degrees of freedom, or 'bits', of a finite region of space behave during the universe's expansion, proposing that they fuse together as space expands based on gravity/field theory duality.

Contribution

It introduces a novel perspective that bits fuse during spacetime expansion, advancing understanding of quantum gravity and cosmological evolution.

Findings

Bits fuse together as space expands.

Gravity/field theory duality supports the fusion process.

Implications for quantum gravity and cosmology.

Abstract

Quantization of gravity suggests that a finite region of space has a finite number of degrees of freedom or `bits'. What happens to these bits when spacetime expands, as in cosmological evolution? Using gravity/field theory duality we argue that bits `fuse together' when space expands.
