Several black hole collisions have been detected. How do they determine if the gravitational waves have been strengthened or weakened by interaction with other event waves?

  • Dark Matter, Dark Energy and all of the Galaxies in between means where was the collision? – James Leismer Mar 28 '18 at 05:43
  • 2 sets of detectors detected the same event at the same point in time. Coincidence? – physics2000 Mar 28 '18 at 06:45
  • The papers are here: http://www.ligo.caltech.edu/page/detection-companion-papers. For a specific observation, see for example: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.241103. If you doubt their methodology, please be more explicit in your question. – Stéphane Rollandin Mar 28 '18 at 08:55
  • Cloud you clarify your question? Are you asking about the possible complications of overlapping gravitational wave signals? Or out interference on the detectors from other (none GW sources, e.g. seismic activity). – TimRias Mar 28 '18 at 09:00

  • You might start with the principle of "linear superposition" (which is a rule about a very large class of waves including weak field gravitational waves). – dmckee --- ex-moderator kitten Mar 28 '18 at 17:56
