# INTERFACE OF GRAVITATIONAL AND QUANTUM REALMS

@article{Ahluwalia2002INTERFACEOG, title={INTERFACE OF GRAVITATIONAL AND QUANTUM REALMS}, author={Dharam Vir Ahluwalia}, journal={Modern Physics Letters A}, year={2002}, volume={17}, pages={1135-1145} }

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… Expand
