A wormhole-generated physical universe with refined approximation

TL;DR

This paper refines a wormhole-based universe model showing that negative pressure from unphysical wormholes can explain the universe's observed acceleration, aligning with cosmological data.

Contribution

It introduces an improved approximation of the wormhole-generated universe model, demonstrating how negative pressure can produce an accelerating universe consistent with observations.

Findings

Negative pressure from wormholes can generate an accelerating universe.

The refined model aligns with the observed sign of the deceleration parameter.

The approach offers a new perspective on wormholes in cosmology.

Abstract

We improved the approximation of the model of the wormhole generated physical universe constructed by Choudhury and Pendharkar. We show here that the negative pressure of the unphysical wormhole can generate the right physical condition to explain the correct sign of the deacceleration parameter $q_0$. The negative sign ofsign of $q_0$ implies an accelerating universe.
