I love it when Brian Greene is on the show. The chemistry between all three of them is great. I vote for more Brian Greene.

Always more Brian Greene, please 🙏

A string theorist was in his office, kissing his secretary. His wife walked in, gasped, and turned to leave. The theorist said, "Wait a while, and I will explain everything!"

Isn't it time for Chuck's graduation as an amateur astrophysicist soon? I'd love to see an episode where Neil and the producers select the questions, and put together a special "Things you ought to know by now"-episode where Neil reads the questions, Chuck replies, and then Neil elaborates. Chuck, we believe in you! 👏

Neil, I am so glad you gave Chuck a celebratory educational certificate!! 😊.. I love your show and it has been very noticeable how much Chuck has learned over the years!! I can tell by the great questions that he ask. Keep up the great work both of you!! I Learn and Laugh every time I watch an episode!! Knowledge and laughter is a great combination.

I love Brian Greene always. He’s such a fascinating and compelling communicator when it comes to the weirder and more complicated edges of science.

Brian Greene is one of the best teachers and my favorite astrophysicist!

Man I just love Brian Greene's ability to explain such complex ideas and concepts. Truly incredible times we live in to be able to witness such insights from a fellow human being.

Chuck is doing an outstanding job managing the show. Loving it gents!

I must say that Chuck learning alot and actually retaining it has been fun to watch over the many videos.. he's coming out with the right answers too so we know he's paying really good attention with the explainers with done Neil . It's fitting that he actually was given a diploma of sorts from Neil for how much he's actually learning and showing it too lol

0:00: 🌌 Astrophysicist Tyson and physicist Brian Green discuss cosmic queries and their popular demand. 5:40: 😮 The speaker discusses their experiences with lucid dreaming and how they became aware that they were dreaming. 10:44: 🔬 The Plank length is a very specific number that represents the smallest possible length in the universe, and equations indicate that going smaller than this length is beyond the reach of today's equations. 15:49: 🌟 The concept of time passing for a photon traveling at the speed of light is explored in this video. 20:22: ! Theoretical physicists use mathematical aesthetics, observation, and experimentation to drive their ideas. 25:33: 🔬 We have a limit on how well we can understand the deep walls of the universe, just like dogs have a limit on how well they can understand quantum mechanics. 30:35: 🔬 Energy input increases the overall mass of an entity, such as a pot of water, as seen in the example of an electric car gaining weight on a full charge. 36:08: ! There is no geometric center of the universe, but if we include the time coordinate, the center would be back in time to T equals zero. 40:44: 🌌 The next major breakthrough in our understanding of the universe may involve a refined understanding of the Big Bang. Recap by T

Can’t get enough of this. Incredible guest. Great comedian. Incredible brains. Ridiculous conversations that make your neurons twitch. Been watching start all for some time now. Thank you gentlemen

Always a pleasure to have Professor Brian Green come on and enlighten us

I'm a huge fan of Brian Greene's books. "Until the End of Time" was an amazing journey of learning for me. Love the idea of using the empire state as a graphic reference of eons passing. For the past 5 years, I've been exploring the hobby of learning about relativity and how the universe actually works, and I've read all of Brian Greene's books and also many other authors. Thanks for having him on start talk again.

On the lucid dreaming topic: I once had a lucid dream in which I realized I was dreaming, and the dream was kind of creeping me out, so I wanted to wake myself up. When I woke up, it turned out that I didn't really wake up at all - I dreamt that I woke up, but was still actually asleep. That also broke the lucid dreaming effect, since I thought I was awake. I was super convinced that I was awake, too, until a few minutes later when I woke up for real. ....Or did I???

Brian greene is an absolute treasure to our generation gifted by the universe

Brian Greene plus Neil plus Chuck equals curiosity at it's finest

I like to see the people and discussions at the edge between the known and the unknown ... Neil is great when he talks about the universe, philosophy, astrophysics and science ...

The way you bring intelligence and inspire us all to see the intelligence in us all is so inspiring. From the bottom of my heart, thank you all!
