On Sept. 14
​ ​
at 4am the LIGO
​detector in ​
​ Louisiana  ​
detected a burst ​
​of gravitational waves, ​7 milliseconds later the LIGO detector in Hanford
Washington detected the same thing. The possibility of this being due to
chance is
vanishingly small
​. What they detected was 2 black holes circling each other at 250 times a
second, one was 36 times the mass of the sun and the other 29 times. The
entire signal only lasted for a fifth of a second.
