Interesting, thanks for sharing!

I definitely don't walk away from any of Brian Greene's content thinking that String Theory is anything close to a confirmed fact at all.

It's been some times since I read his earlier books, possibly his tone has changed?

I'll also say, I'm far from a professional physicist. I'm reading and watching for fun and intellectual curiosity, not to learn physics with the goal of doing my own research. I always thought of String Theory as being more of a study of math where many people have unsuccessfully tried to apply it to physics. And, that it's lead to some really interesting ideas. I just find him and his work really enjoyable.

I think her point is more that his tone hasn't changed. If you're curious I would just watch the video. Angela comes with the perspective of also having read his earlier books and having liked them.
