I enjoy her videos but was surprised to see that there is a small but organised group that has something of a vendetta against her, basically accusing her of being a pseudoscientific hack.
I'm not exactly certain what that's all about, but I strongly suspect it's because she's one of the more vocal physicists who are expressing serious doubts about the validity of string theory, as well as skepticism about certain
other significant dogmas in physics, like cosmic inflationary models, singularities, and the nature of entropy.
Her views are shared by such renowned physicists like Roger Penrose, Sheldon Glashow, and the late Richard Feynman, but they're a lot more difficult targets to make a plausible case against for being pseudoscientific hacks.
