# Primordial density fluctuations generated by wormholes

## TL;DR

This paper investigates how wormholes in an expanding universe can influence primordial density fluctuations, potentially leading to observable anisotropies in the cosmic microwave background.

## Contribution

It introduces a model of wormholes affecting the inflaton field's correlations, revealing translation invariance violation during cosmic expansion.

## Key findings

- Two-point correlation function of inflaton mimicking scalar field calculated
- Violation of translation invariance identified during wormhole influence
- Potential link to anisotropies in cosmic microwave background

## Abstract

We studied the influence of a wormhole existing in the expanding Universe and passing through the horizon volume on the energy density of the Universe. The two-point correlation function of a free massless scalar field mimicking the inflaton was found. The revealed violation of the translation invariance during the process in question might be potentially envisaged in the anisotropy in cosmic microwave background radiation map.
