I wouldn’t say she’s bad or non-credible. Her viewpoint is in a minority but is legit. I just guessed it was her because she keeps harping on the same points and I’m like, ok, we get it. She wrote a book saying the same thing too. Maybe it’s worth reading, idk Some perfectly good physics is inherently not falsifiable though, like general relativity’s predictions about black hole interiors. So she is a bit too hung up on that issue.
