Beyond the Quantum

TL;DR

This paper revisits de Broglie's pilot-wave theory, highlighting its potential to extend quantum physics beyond standard interpretations, with implications for cosmology and relic particle detection.

Contribution

It emphasizes the overlooked significance of de Broglie's theory and explores its potential experimental evidence in cosmology and particle physics.

Findings

De Broglie's theory allows non-local signals and uncertainty violations.

Potential evidence could be found in cosmic microwave background anisotropies.

Detection of relic particles with exotic properties may support the theory.

Abstract

At the 1927 Solvay conference, three different theories of quantum mechanics were presented; however, the physicists present failed to reach a consensus. Today, many fundamental questions about quantum physics remain unanswered. One of the theories presented at the conference was Louis de Broglie's pilot-wave dynamics. This work was subsequently neglected in historical accounts; however, recent studies of de Broglie's original idea have rediscovered a powerful and original theory. In de Broglie's theory, quantum theory emerges as a special subset of a wider physics, which allows non-local signals and violation of the uncertainty principle. Experimental evidence for this new physics might be found in the cosmological-microwave-background anisotropies and with the detection of relic particles with exotic new properties predicted by the theory.
