Gravitational wave holography

TL;DR

This paper develops a theoretical framework for gravitational holography, proposing that gravitational waves can be used to reconstruct other gravitational waves, analogous to optical holography, despite their weak signals.

Contribution

It introduces a novel theory of gravitational holography where all waves involved are gravitational, extending holographic principles to gravitational waves.

Findings

Theoretically demonstrates gravitational wave holography feasibility.

Shows gravitational waves can be reconstructed using holographic methods.

Highlights the potential for gravitational wave imaging despite detection challenges.

Abstract

We represent and discuss a theory of gravitational holography in which all the involved waves; subject, reference and illuminator are gravitational waves (GW). Although these waves are so weak that no terrestrial experimental set-ups, even the large LIGO, VIRGO, GEO and TAMA facilities, were able up to now to directly detect them they are, nevertheless, known under certain conditions (such as very small wavelengths) to be almost indistinguishable (see P. 962 in Ref. \cite{mtw}) from their analogue electromagnetic waves (EMW). We, therefore theoretically, show, using the known methods of optical holography and taking into account the very peculiar nature of GW, that it is also possible to reconstruct subject gravitational waves.
