Questions
1. How these detectors read distance of the event? In order to assert that the rate peaked 8*10^9 years ago, we'd need to know distance. Surely it's not based on amplitude
2. Galaxies collide. Is there reason to think that many galaxies contain a central supermassive (10^9 solar mass) black hole, and that such holes have collided as well? Perhaps too rare to be seen in five years?
- jorpal 6y ago1. The frequency evolution of the measures waveform depends on the mass of the objects. Once you know the mass you can use the amplitude to infer the distance. 2. Galaxies do contain supermassive black holes at their centers. However the frequency response of ground based detectors preclude observation. When space based detectors are operating we will see those collisions.
