Searching for Wormholes with Gravitational Wave Scattering

Hong Zhang

Abstract

Wormholes bridging distant places of the universe are well-known solutions of general relativity. However, no hint of their existence has been found yet. In this work, we propose using the gravitational wave scattering off spherical wormholes to search for their existence. We carefully calculate the reflected and transmitted waveforms with time-independent scattering theory. Our results quantitatively show the signatures in the waveforms on both sides of the wormhole.
