Are you talking to me? You linked my post, so you must be talking to me... I never said that gravitational waves could only come from black holes. I understood what was linked, and I don't see why you feel like you need to explain this to me, besides an obvious case of Dunning Kruger's disease. What he said was that, according to him, the type of waves they picked up are the best evidence that black holes even exist. This method of picking them up is only indirect evidence. You guys keep saying that there is direct observational evidence. If there was direct observational evidence, then he would just be completely wrong about this. People make bold scientific claims all of the time. Some of the pictures on the net must have not survived the scientific scrutiny they would have received from making those claims.
