Gravitational waves are ripples in space-time fashioned when a large object strikes round, so if there are any extraterrestrials driving gigantic spacecraft round our galaxy, the Laser Interferometer Gravitational-Wave Observatory (LIGO) within the US might doubtlessly detect them.
Gianni Martire at Applied Physics, a analysis institute in New York, and his colleagues calculated how massive such a craft must be, and how briskly it might have …
