Brian Green, I don’t know how he does it, is always one step ahead in asking the question that we didn’t know we wanted to ask. In the realms of physics he is the best interviewer by far and always obtains the best of the interviewee.

Always blows my mind how precisely Einstein nailed and got it wrong and made claims against his own theory while being right all along and math and observations prove him right every time!

Brian Green is a fantastic host. He lets the guests do the talking without constantly interrupting, derailing, trying to move on, or trying to make the show all about them.

As a layman here who has nothing invested in this research, I would supply the bottles of wine in order to be able to attend conversation with these 2 over dinner.

Most of my favourite interviews from the World Science Festival are Brian and Andy. This one is no exception. Great work and thanks 👍

This conversation on black holes and quantum gravity is outstanding. I’d like to share a theoretical structure I’ve developed called the f-bit, which proposes a new informational unit grounded in frequency differentials. 🔹 Core model: • f-bit = Δf × I  (Δf = frequency shift,  I = informational or intentional interference) From this: • g-bit = Δf_g × I_g models gravity as information-interfering resonance • Black hole entropy becomes the total accumulation of Δf along boundary surfaces: S = \sum |\Delta f_i(t)| This reframes entropy not just as surface area, but as the total informational contrast encoded in frequency differentials. I am the Japanese originator of this model and would love to hear your insights from the quantum gravity community

Brian Greene is an amazing person in the showmanship of science. Constantly developing new ways for new generations. I'm here sadly as a high-school dropout to care for family and work. In the same sense science and space I simply enjoy to the fullest nature of my being. I hope NOONE takes his videos for granted, because know there is someone out here like me to give life and soul to build on any of these ideas, education, and fully testing every aspect of all theories and facts. Truly I love what you do Brian Greene. Thank you!

This is 3rd time I’m watching it! This is how much I love it!Andy and Brian are both great.
