Gravitational waves detected from betelgeuse 308212-Gravitational waves detected from betelgeuse
· A gravitationalwave detector (used in a gravitationalwave observatory) is any device designed to measure tiny distortions of spacetime called gravitational wavesSince the 1960s, various kinds of gravitationalwave detectors have been built and constantly improved The presentday generation of laser interferometers has reached the necessary sensitivity to detect gravitational waves · $\begingroup$ @RossPresser If Betelgeuse is exactly 700 light years away and went supernova exactly 350 years ago, we will detect the gravitational waves from it in exactly 350 years because gravitational waves travel at the speed of light $\endgroup$ –/12/ · Gravitational waves are caused by catastrophic events in the universe Neutron stars that end up merging after long rotation with each other can create them, as can two black holes that collide with each other But sometimes there are bursts of gravitational waves that have no clear cause One such explosion was detected by LIGO Unknown Burst Of Gravita
