It's still no proof of existence of black holes. It's like saying that a lightning storm is proof of Thor, because the legends say he wields the very same lightning. The cause could be something entirely different (spontaneous spacetime ripples, alien generators, whatever really).

> It's still no proof of existence of black holes

You've shifted the goal posts in this sentence. Previously, you said there was no evidence of black holes. Now you're upped the scale to demanding proof.

The previous commenter wasn't claiming that LIGO detections were proof of black holes. They said that they were evidence of black holes.

The LIGO detections, by all reasonable metrics, would certainly qualify as evidence of black holes. Of course, I agree with your assertion that taken alone, LIGO detections are not proof of the existence of black holes. Taken with the significant body of other evidence we have, though, I would say the sum total of evidence that we have is a strong indicator that black holes exist.

The fact that scientists were able to accurately predict what this black whole should look like using the math at our disposal is about as good a piece of evidence as one can get.

General Relativity is based on familiar observations, not mythical beings. It's not nearly that complex. Crystal healing and astral travel likewise don't even have a mathematical basis that is compatible with observations about reality, so there's no comparison to draw.
