What Methods Have Scientists Used to Confirm the LIGO Discovery of Gravity Waves?

Question: Information says that the gravitational waves, recently detected by LIGO, correspond (according to Einstein theory equations) to the effect of two black holes merging (with the masses of both black holes being estimated). So the fact of two celestial … Continue reading
