Emergent Spacetime and The Cosmological Constant

TL;DR

This paper explores how emergent gravity offers a novel perspective on the origin of spacetime and addresses the cosmological constant problem by explaining dark energy and flat spacetime as emergent phenomena.

Contribution

It introduces a new framework where gravity and spacetime emerge from underlying principles, providing insights into dark energy and the cosmological constant.

Findings

Emergent gravity explains the dynamical origin of flat spacetime.

The approach offers a potential solution to the cosmological constant problem.

It presents a radically different picture of spacetime origin.

Abstract

We address issues on the origin of gravity and the dark energy (or the cosmological constant) from the perspectives of emergent gravity. We discuss how the emergent gravity reveals a noble, radically different picture about the origin of spacetime, which is crucial for a tenable solution of the cosmological constant problem. In particular, the emergent gravity naturally explains the dynamical origin of flat spacetime, which is absent in Einstein gravity.
