Wormholes and Time Travel? Not Likely

TL;DR

This paper argues that traversable wormholes, often proposed for faster-than-light travel and time travel, violate fundamental physical principles like energy conservation and the energy-time uncertainty principle, making such scenarios unlikely.

Contribution

It critically examines the physical plausibility of traversable wormholes by highlighting violations of core physical principles, challenging their feasibility for faster-than-light or time travel.

Findings

Traversable wormholes violate local energy conservation.

They also conflict with the energy-time uncertainty principle.

Such wormholes are unlikely to exist within known physics.

Abstract

Wormholes have been advanced as both a method for circumventing the limitations of the speed of light as well as a means for building a time machine (to travel to the past). Thus it is argued that General Relativity may allow both of these possibilities. In this note I argue that traversable wormholes connecting otherwise causally disconnected regions, violate two of the most fundamental principles physics, namely local energy conservation and the energy-time uncertainty principle.
