Observing of background electromagnetic radiation of the real sky through the throat of a wormhole

TL;DR

This paper numerically investigates how the cosmic microwave background radiation appears when observed through a wormhole, producing temperature maps and visualizations that differ from black hole images.

Contribution

It introduces a numerical method to visualize CMB radiation through a wormhole, providing distinctive observational features compared to black holes.

Findings

Generated temperature distribution maps of CMB through a wormhole

Produced visual images of the Milky Way seen via the wormhole

Identified characteristic features distinguishing wormhole images from black hole images

Abstract

The numerical investigation conducted in this paper addresses the problem of CMB radiation imaging as seen through the throat of the Ellis-Bronnikov-Morris-Thorne wormhole. It is assumed that both throats of the wormhole are relatively close to our stellar neighborhood, so close that the view of the ambient background radiation by an observer at the other throat of the wormhole is virtually identical to that seen from the Solar System neighborhood. A map of the temperature distribution of the cosmic microwave background radiation observed through the mouth of the wormhole has been constructed as well as a view of the Milky Way through the mouth of the wormhole. The resultant image contains characteristic details that enable it to be distinguished from an image produced by a black hole.
