I have a question that maybe comes from something that i didn’t understand quite well or misunderstood.
We said that at the moment the black holes collided a part of the collision energy was “used” to generate (or transformed) in gravitational wave (if i am not mistaken, the amount of ca. 3 solar masses). In the beginning of the lecture we said that in general gravitational waves don’t interact that much with matter. So, if they don’t interact that much (for whatsoever reason that needs to be discovered) and have so much energy and travel with the speed of light…. how can it be, that the force, that they exercise in the mirrors of LIGO is so small? Were did the whole energy go? was it converted everything to make the fabric of spacetime vibrate with the speed of light? If so, if we would have 3 solar mass and 6 solar mass of energy transformed in a gravitational wave, would the outcome still be the same?
Thank you 🙂
