Brian Greene is the single most suitable person as a host for this format

Brian is such a great interviewer in the sense he asks guests to explain topics for all audience members.

I like this format that assumes people have learned at least the very basics what's the topics being discussed and doesn't rehash the same thing over and over at a third grade level

I hope I live long enough to see quantum theory and general relativity resolved by some unified theory. If not I hope we discover something new and very interesting.

Greene is an exceptionally skilled interviewer and on another level when compared to everyone else.

When I was like 16 I remember reading your "The Elegant Universe" and since then I've been fascinated about physics. It's incredible that now I can watch these fabulous interviews and panels on the internet, something that would've never been shown on TV back then.

I've watched so many of these and read about quantum mechanics for many years. Not in a deep study type of way or anything. But I do find it fascinating that every time you get to the stage of asking "what would you say to someone who say that the probabilities is us just missing information", the answers are never very fulfilling to me. It still feels like the same classical "we just know" type of answer that has happened with scientific educators in the past and up until now. I'm not saying the world has to be definite in its outcomes, although it might and therefor free will cannot exist, but I digress. But I'm also not betting on our quantum probability calculations to be as good as they can be. Which would mean, lacking information of a system. I guess I just find it a bit arrogant to think you know that there's no more information to be gained in that realm. As that's basically what you'd have to do when claiming "it just is that way".

what a time to be alive to be able to listen to two geniuses like this

My favourite comment so far is "You can not Quantiized gravity." I mean, technically that's true.

Raphael Bousso's explanations really cleared some of the confusions I've had for a long time.
