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.

This article delves into a fascinating topic at the intersection of General Relativity and Quantum Cosmology. The authors explore the formation of wormholes, those speculative passages connecting different points in space-time. They propose a mechanism involving the interaction of massive objects within parallel universes modeled as branes.
Wormholes, theoretical shortcuts through space-time, capture the imagination, but their existence remains purely theoretical. The article discusses the conditions for wormhole formation, where gravitational attraction between massive objects overcomes resistance from brane tension. This concept aligns with theories exploring the behavior of gravity at both macroscopic and microscopic scales.
The authors highlight that more massive and compact objects are more likely to meet the conditions for wormhole creation. This aligns with established theories in physics, where larger gravitational forces can significantly bend space-time. The suggestion to search for wormholes near black holes, compact stars, or massive microscopic relics resonates with ongoing astronomical observations and theoretical predictions.
The study’s implications extend to potential wormholes connecting objects within the same universe, broadening the scope of their formation mechanism. The interdisciplinary nature of this work, blending concepts from General Relativity and High Energy Physics, is a testament to the complexity and depth of modern theoretical physics.
Now, breaking it down:
-
Wormhole Formation: The article explores the process of how wormholes might form, involving interactions between massive objects within parallel universes represented as branes.
-
Parallel Universes (Branes): These are theoretical constructs in certain models of cosmology that suggest our universe could exist alongside other parallel universes, potentially separated by higher-dimensional spaces known as branes.
-
Gravitational Attraction vs. Brane Tension: Wormhole formation depends on the balance between gravitational attraction and the resistance posed by brane tension. When the former overcomes the latter, it allows the branes to deform and form a wormhole.
-
Massive and Compact Objects: The likelihood of wormhole formation increases with the mass and compactness of objects involved, aligning with gravitational theories where stronger gravitational forces can significantly warp space-time.
-
Search Areas for Wormholes: The article suggests potential locations to search for wormholes, including near black holes, compact stars, or massive microscopic relics, based on the likelihood of meeting the conditions for their formation.
-
Wormholes within the Same Universe: The proposed formation mechanism is applicable not just for connections between objects in parallel universes but also for objects within the same universe, expanding the scope of potential wormhole scenarios.
-
Interdisciplinary Nature: The study draws from concepts in General Relativity and High Energy Physics, showcasing the interdisciplinary nature of theoretical physics and its complexity.
This intersection of cosmology, gravity, and theoretical physics offers tantalizing possibilities, although the existence and practicality of traversable wormholes remain speculative within the realms of current scientific understanding.
