LIGO, the gravity wave detecting interferometer, has arms 4 kilometers long. Along that distance, it can detect a change in length one ten thousandth the diameter of a proton. With an instrument that sensitive, it can just barely detect a handful of gravity waves a year, out of the thousands? that occur in the observable universe. Gravity waves are subtle things.
- Retric 3y agoI guess the question becomes if tectonic plates be more or less sensitive? They are significantly impacted by tides for example.
- deepsun 3y agoThere are different kinds of gravitational waves, LIGO doesn't see them all. Related: https://cplberry.com/2015/01/10/1408-0740/ https://cplberry.com/2015/01/10/1408-0740/
- Gravityloss 3y ago> ground-based detectors like LIGO measure the higher frequencies, pulsar timing arrays measure the lower frequencies, and space-borne detectors like eLISA measure stuff in the middle. Does this data correlate with weather events, earthquakes or cosmic rays?
- tobinfricke 3y agoWeather events and earthquakes - no. Cosmic rays - Astrophysical events that generate gravitational waves can also generate electromagnetic and particle emissions. If a black hole crashes into a neutron star, all kinds of stuff is going to come out.
