ABOUT WORLD SCIENCE FESTIVAL:
The World Science Festival (WSF) is a multimedia organization bringing the most transformative ideas in science to global audiences. Through long- and short-form videos spanning physics, cosmology, quantum mechanics, biology, neuroscience, consciousness, medicine, space exploration, the dilemma of free will, artificial intelligence, engineering, robotics, and beyond. WSF gathers world-renowned scientists, artists, and thinkers for dynamic discussions, debates, lectures, performances, films, and immersive live experiences.

Founded in 2008 and headquartered in New York City, the World Science Festival is a production of the World Science Foundation, a 501(c)(3) nonprofit organization. Our mission is to cultivate a public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future. With live events reaching millions worldwide and hundreds of millions of digital views, WSF continues to expand its global impact through festivals, educational initiatives like World Science U, and digital content that explores the near and far future of our world.

So cool. Anton Petrov was talking about that polarized black hole.
If the big bang is an implosion like a cosmic black hole/white hole, then dark energy is just gravity seen from the point of view of inside the black hole.
illustration: take a rubber membrane to simulate space time. Apply a vacuum cleaner hose to simulate a quantum fluctuation and a black hole.
The vacuum generates a balloon. 🎈
From the outside, it illustrates gravity pulling on space time.
From the inside surface of the balloon, it illustrates dark energy expanding space time.

Obviously, both are caused by local energy differential in the vacuum, also known as quantum fluctuations at different scale.

At small scale the local energy differential generates a flow (same process as Hawking radiation) where virtual particle are separated.

Just like the waves of the sea separates sand on the beach according to weight and size.

That flow at larger scale is calked cosmic web.

Good news: The univers can do that forever.

Enjoy.

Subtle consequences: the big bang is happening now. In your mind 😋

Brian Greene is a wonderful person in his ability not only to make a difficult subject easier to understand but to make the subject wholly enjoyable. I wish there were more like him around. Ray.

Great discussion on a number of topics along with a nice oral history on the dynamics of the development of space expansion . Dr. Greene is a terrific and well-balanced moderator.

Thank you for this series. It makes me smile.:buffering:

@Proticor 5 years ago

That truly was a fantastic conversation. Thank you both to the 2 Brians and the WSF team.

@goodnoodle5678 5 years ago

I can’t wait for more updates on these phenomenal theories! I’m jealous of the astrophysicist Brian mentioned from the year 100,000,002,021.

I never thought of neutrinos possibly being in a medium so dense that they could be responsible (at least partially if not essentially fully), for blowing that medium apart. Wow! The physics of supernovae are truly remarkable.

@wesc6755 5 years ago

People like Brian Schmidt are my rock stars. Great conversation.

The weather is complicated: Consider that to predict precipitation you have to follow three phases of water, various forms of ice moving in a 10 km high column at speeds between 5 and 20 m/s vertically with temperatures between 180 and 300 K.

Hi Brian, I have enjoyed watching numerous, if not most of the episodes you’ve produced and am just curious what kind of microphone do you use for these? Thanks, Glenn

@roberthutchison8197 4 years ago

I was pleasantly surprised when I heard you were born in Montana (Brian Schmidt), which is my home state. Congratulations on the Noble Prize!

@kagannasuhbeyoglu 5 years ago

It was great👍
Thanks a lot Brian Greene and Brian Schmidt. Perfect content.

@ramsayfarran992 5 years ago

Very enjoyable. Held my interest through the whole interview (not easily achieved !)
Thanks

@iam007richie 5 years ago

Please do stream it in June or at least please upload the videos after the event on this channel. Thanks!

@zetacrucis681 4 years ago

It's so great to hear from Brian Schmidt. Thanks WSF!

@dreed7312 5 years ago

Amazing that none of them were harmed! This is one of the craziest things I've seen in awhile.

@ryandonnelly2661 5 years ago

Loved this latest episode! Huge fan of the both of you

@silberlinie 5 years ago

Why doesn't the video have a release date?

@kelvinlu8885 5 years ago

Finally an updates in three month. Thank you Dr Greene.

@prajwalpreteesh314 5 years ago

Thanks for introducing very eminent personalities and creating conditions for a layman to have access with them. When you are discussing with him at one point of time he told that he will not subscribe to the idea of Big Bang singularity. What he intended to say on this point.please elaborate on this point if you find time.
