How to form a wormhole

TL;DR

This paper presents a simple model for wormhole formation involving two branes with massive objects, showing that strong gravitational attraction can deform the branes and create wormholes, especially around black holes or compact stars.

Contribution

It introduces a new mechanism for wormhole formation based on brane deformation due to gravitational attraction between massive objects.

Findings

More massive objects are more likely to form wormholes.

Wormholes can connect objects within the same universe or across different universes.

The formation depends on the balance between gravitational attraction and brane tension.

Abstract

We provide a simple but very useful description of the process of wormhole formation. We place two massive objects in two parallel universes (modeled by two branes). Gravitational attraction between the objects competes with the resistance coming from the brane tension. For sufficiently strong attraction, the branes are deformed, objects touch and a wormhole is formed. Our calculations show that more massive and compact objects are more likely to fulfill the conditions for wormhole formation. This implies that we should be looking for wormholes either in the background of black holes and compact stars, or massive microscopic relics. Our formation mechanism applies equally well for a wormhole connecting two objects in the same universe.
