Interface of Gravitational and Quantum Realms

TL;DR

This paper discusses the potential for detecting quantum gravitational effects, such as spacetime foam and modified wave-particle duality, using advanced superconducting devices, challenging longstanding skepticism.

Contribution

It reveals that the traditional argument against quantum gravity phenomenology has been refuted and highlights new experimental possibilities for observing quantum gravitational phenomena.

Findings

The forty orders of magnitude argument was defeated over 25 years ago.

Potential detection of spacetime foam signals is now feasible.

Superconducting quantum interference devices can study gravitationally-modified wave-particle duality.

Abstract

The talk centers around the question: Can general-relativistic description of physical reality be considered complete? On the way I argue how -- unknown to many a physicists, even today -- the ``forty orders of magnitude argument'' against quantum gravity phenomenology was defeated more than a quarter of a century ago, and how we now stand at the possible verge of detecting a signal for the spacetime foam, and studying the gravitationally-modified wave particle duality using superconducting quantum interference devices.
