Waves and causality in higher dimensions

TL;DR

This paper introduces a new wave-like solution in five-dimensional relativity that resembles matter waves and explores how extra dimensions can clarify their behavior and causality, with potential laboratory tests.

Contribution

It presents a novel five-dimensional wave solution and links matter wave behavior to extra dimensions, offering new insights into causality in higher-dimensional theories.

Findings

Wave-like solutions in 5D relativity resemble matter waves

Extra dimensions help explain wave behavior and causality

Potential for laboratory testing of higher-dimensional wave properties

Abstract

We give a new, wave-like solution of the field equations of five-dimensional relativity. In ordinary three-dimensional space, the waves resemble de Broglie or matter waves, whose puzzling behaviour can be better understood in terms of one or more extra dimensions. Causality is appropriately defined by a null higher-dimensional interval. It may be possible to test the properties of these waves in the laboratory.
