Experimental test for extra dimensions in Kaluza-Klein gravity

TL;DR

This paper proposes that non-flat solutions in 5D Kaluza-Klein gravity could serve as quantum wormholes, and under strong external fields, they might become classical, offering a potential experimental test for extra dimensions.

Contribution

It introduces a novel idea that quantum wormholes in higher-dimensional gravity can be inflated into classical objects via external fields, suggesting a new experimental approach.

Findings

Potential for experimental detection of extra dimensions.

Proposal that external fields can inflate quantum wormholes.

Link between higher-dimensional solutions and observable signals.

Abstract

5D Kaluza-Klein gravity has several nonasymptotically flat solutions which generally, possessed both electric and magnetic charges. In this paper we suggest that these solutions can act as quantum virtual handles (wormholes) in spacetime foam models. By applying a sufficently large, external electric and/or magnetic field it may be possible to ``inflate'' these solutions from a quantum to a classical state. This effect would lead to a possible experimental signal for higher dimensions in multidimensional gravity.
