Observable effects from spacetime tunneling

TL;DR

This paper explores the theoretical conditions for spacetime tunnels like wormholes to exist in the universe and predicts observable effects such as lensing, frequency shifts, and luminosity increases at the tunnel's throat.

Contribution

It provides a theoretical analysis of the conditions for embedding spacetime tunnels in Friedmann space and predicts potential observable signatures.

Findings

Predicted lensing and frequency-shifting effects

Discontinuous background temperature changes

Luminosity enhancement at tunnel throats

Abstract

Assuming that spacetime tunnels -wormholes and ringholes- naturally exist in the universe, we investigate the conditions making them embeddible in Friedmann space, and the possible observable effects of these tunnels, including: lensing and frequency-shifting of emitting sources, discontinuous change of background temperature, broadening and intensity enhancement of spectral lines, so as a dramatic increase of the luminosity of any object at the tunnel's throat.
