Brian Greene is one of my favourite physicists, not just for his obvious brilliance, but also because of his entire approach to the subject. You'll never hear him disparage others, and he has a healthy amount of respect even for non-scientists. Consider the way he engages with this other brilliant physicist: Stefanie Milam. Unlike, say, Lawrence Kraus or Neil DeGrasse Tyson, he actually allows the guest to speak. All of which leaves you thinking you've learned something, even if you haven't:)

...when the interviewer does their homework. This is great stuff!

I've just spent 51 minutes of my life with great pleasure. Thanks! Hello from Russia!✋😃

This is why I love scence, let's us know our place - since we are sharing this little planet, it's in our best interest to at least get along 🤗

When Brian can sit back and listen like the rest of us you know this woman knows her stuff. Really enjoyed this 😎

Ah, the wonder of knowing something no one else in the world knows, and the thrill of spreading that knowledge: you lucky people! Keep the thrills going with our thanks.

Greene is such a marvelous and gifted teacher.

How appropriate in a talk about water and life to see each speaker with a glass of water.

I see a Brian Greene science video and I click

videography in this one is SICK !!!!! Great job!!!

Great to see Greene (a theoretical physicist) get amazed by observational astronomers ❤

Brian Greene, thank you for what you do 🙏

Outstanding interview by Brian, allowing Stephanie’s scientific discussion to blossom for the layman. Nice to see Brian bringing Stephanie back to the layman’s arena when she would get on a PhD discussion tangent role … fine for PhDs, not so much this audience. Thanks to both, best.

BG going with the mad scientist look these days. I approve of this.

Thank you, Dr. G. You attract the most interesting guests for the most interesting subjects. This has been one of the best. Dr. Milam is an excellent communicator with a deep knowledge of her subject. Thank you both.

Dr Greene is such a great host and presenter. I think his most admirable quality, besides his intellect, is his low ego. He doesn't have to act like the smartest person in the room (cough cough Neil deGrasse Tyson) and let's others teach him (and us) in a very comfortable and non combative way.

very excited for what the future discoveries will hold for us.

We learn at a fast pace today one answer in Physics leads to more than a hundred questions and yes we are leap-frogging our knowledge of the Cosmos the major factor is that we have JWST to quantify what we think we are really looking at what it means to us for our future, The Cosmos is like a super colossal pinball machine things come in and things disappear in microseconds I hope what we find out is accurate enuff to help us make the major changes to our knowledge that we need to survive and maybe keep our planet Earth in the condition that helps us. I truly love the interest and comments said here.

Water is vital... but so are you. Thanks for the video.

Thanks for this! it was amazing

The amazing evidence of it just being by chance that our solar system was born and birth of Earth and evolution of life and birth of humans and for us to be here to discuss all this is just mind blowing!!

She was absolutely amazing and what a marvelous human mind. Thanks for all of your insight Stefanie Milam! Well done.

Always like a good episode of The World Science Festival.

Brian Greene❤ amazing as always. Thank you so much

Great discussion

Best news since the galaxy conceived Earth.

She exuded all the excitement! Loved this conversation!

This is amazing!!! Thank you so much!

A tattoo for teaching! Wow, I've never seen anybody with a useful tat before. What a great educational tool and reason.

Brian is a Gangsta!

The intro piano is soooo nice, great choice in production

This was a great interview, thanks WSF, hoping to watch more of these talks this year!

I very much enjoyed the more "practical" aspects of this discussion.

Great Video thanks for sharing!

WOW!!! TY Dr. Green a MILLION TIMES!!!!!! ^.^

Eye opening, as always! 🎉🌐🌟💫

Earth's water came mostly from the Sun: protons reached Earth's oxygens and still reaching and producing water in Earth's atmosphere.

JWT IS SO IMPRESSIVE. What many may not realize is that IF EXOPLANETS are found Say - 1/3 of way across the Galaxy (Milky Way) - That Planet's Light has been traveling to Earth for 30,000 to 50,000 Years. A lot could have happened since then. For Galaxies Millions of Light Years away, that could be a lot of change...or evolution.

AWESOME !!!!!! 👾

This is my hypothesis. The enigmatic nature of black holes and solving the information paradox. In this theoretical framework, the photon sphere of the black hole acts as a "white hole" emitting information in the form of Hawking radiation. This emitted radiation, being a quantum state vector, imprints onto the holographic screen surrounding the black hole as a lattice of qubits or "Plixels." The lattice of qubits represents the encoded quantum information about the properties and characteristics of objects that have fallen into the black hole. The mathematical information contained in this quantum state vector describes various attributes, including velocity, acceleration, and the probability of spin states. This novel approach hints at a new type of physics that explores the relationship between black holes, quantum mechanics, and information theory. The idea of a holographic universe, programmed with bits of light in the form of Hawking radiation and encoded onto the lattice of qubits, holds the potential to unveil profound insights into the fundamental workings of our universe.

Top marks 🙂

That tatoo was hilarious😂 18:26

she is awesome

Copied from my last night comments and happy to watch this tonight. I went to school without laboratory I don't consider myself a science because I am not. And I don't want even to make efforts to acquire titles attached with my name because that is gonna create personal actualization which is a big cause of many human faults as it creates higher expectations from other people and that person who holds those titles tries to defend them by all costs whether in political or in business instead of acting and interacting with people as a normal human being who makes mistakes, who learns new things, who doesn't know many of the things who accepts and admits faults honestly, who asks forgiveness when they hurt others and compensate others if they did anything bad to countable (physical) by actions and regrets and apologizes when they hurt others in words and make much effort in self discipline of never hurting any one intentionally but that is not passive quality and weakness. Who doesn't regret and doesn't hesitate to denounce horrible acts including theirs first and then other people's This topic of food security was well addressed which when lacked creates "food insecurity" But quite different topic, I often hear climate change and climate justice and that countries most affected by climate crisis are the poorest. I also hear carbon dioxide (CO2) discussed which is the gasses animal breath out (exhalation process) and plants take. Ok. We also know that carbon monoxide is (meaning carbon with single oxygen at molecule level) reaction of two elements at gas state (substance state .... solid .... liquid and gas). Ok. This state is always due to the level of temperature (0 degree is the center) above 0 degree is hot or + and below is cold at substance level not human level because water is the center or queen measurement used at classification with the temperature so 0 deg is the freezing (ice point of water) which is two elements of hydrogen and one element of oxygen at molecule level or you can forgive me and say two atoms and one atom at this level because element is made up of atoms. Ok. Carbon monoxide needs more chemical reactions and that is why it takes one more oxygen to become stable at the electrons +- (loosing and gaining between the elements in reaction) gases which are usually in the category of the periodic table in chemistry depending on the electrons cycle in outer layer with the atoms to create elements and between the chemicals (with other elements to create molecules). First, carbon is eating the oxygen usually present in the lower atmosphere as gas. I said as a gas because with water it needs process to purity from it. Ok. When temperature of the earth goes up, snows will heat up and make rivers to follow to the seas because sea level is the lowest of the earth and that why altitude is measured from the sea level. Can we imagine the level of effects of such water follow not only in erosion but also every thing else. We can even bear in rain floods. But I hope, I am wrong and the solid snow oceans, seas and on lands are already in the sea level and will not make any water follow.

Happy FRIDAY ~ 😇

Nice

Some planets may have evolved the ability to breed Centaurs, Dryads, gargoyles, penguins with two hands, flying chimpanzees...🦄 The genes of these new species are preserved in the ice ball at the center of these planets. 🧊 These planets periodically melt the central ice ball, releasing new species onto the surface.🦠🐋🦭🐖🎎

I don't understand, so the Brownian motion velocity of the original water molecules was greater than 7 miles/sec? That's how hot the Earth was? Can someone do a calculation for that?

4:53 would make a great album cover

Do we have rings around Earth such as this that are detectable with James Webb telescope ?

36:22 Formalhaut is at 25 light years. Not 10000. Almost three orders of magnitude wrong!

wow

Of course our solar system is unique Brian, it’s the only one we know of to have life.

Better than a Ted talk!

Can water be generated from its constituents via the earth formation itself? If the earth was a super furnace and abundant with ingredients can it spew from volcanic suface interaction with its relativly cool crust? AKA can we fog the glass of our planet to bring enough mist?

When do we get to see a James Webb of earth?

Vrey cool stuff.

The moment a particle is a wave; it has to be a conscious wave! Gravity is the conscious attraction among waves to create the illusion of particles, and our experience-able Universe. Max Planck states: "Consciousness is fundamental and matter is derived from Consciousness". Life is the Infinite Consciousness, experiencing the Infinite Possibilities, Infinitely. We are "It", experiencing our infinite possibilities in our finite moment. Our job is to make it interesting!

For any late watchers of this program, you can be assured that all of the Cosmos is in perfect harmony with our Creators will! Find answers in the four gospels you can trust. :-)

Is that image of Uranus natural light as we would see it with the naked eye ?

Dear NASA, your mom thought I was big enough -Pluto

Well my question is, does earth have rings?

" we are stardust, we are golden..."

Where did the water from mars+atmosphere go to?

For Earth, Theia.

Question 4: Where did the asteroids get their water from?

The question isn't where did the water come from....but where did the oxygen come from as it is the more complicated rarer atom. We need to back to epochs with fungus only for answer.

LISTEN KIDS (in short, the real world has two fields who form one particle electron=photon: magnetic is perpendicular to the plane of whirpool which produces electric field falling into that whirpool and emerging as magnetic field), THIS KNOWLEDGE WAS REVEALED IN THE YEAR 2000 (I just needed to learn English to transfer it to you): electron is photon (electron is a real atom which is a manifestation of electric and magnetic perpendicular fields like whirpool or eddy or black hole), left and right electrons form neutrino, gravity is uncompensated (or relativistic) electric field of proton (smaller particles consist of bunch of electrons and gravity there is called strong and weak force/field), proton consist of approx 2000 electrons, neutron is electron plus proton, light has no colors since it is a bunch of photons at various distances between themselves traveling in the same direction like thrown sand particles in the air, the red shift is not only due to Doppler effect, but and due to spatial dispersion both due to angular divergence and due to absorption of some photons by matter particles on the path (overall effect is red shift, like averaged distances between photons=electrons falling on averaged areas gives a sensation of frequency and color), a single photon has got no frequency. Universe is INFINITE and ETERNAL, we just cannot see (and will never be able) very deep in space since the lack of PHOTONS reaching us.

📍38:27

Dr. Milam looks like she came out of a 17th century Flemish painting,

I feel like earth was just a ball of ice in the beginning, and once it got struck by a huge rock like asteroid it gave us the material needed . Because the amount of water here is just crazy to think it came like buckets of water filling a pool. I’d say the pool was already full, then it got floaties and other things added or thrown in. My opinion anyways.

That lady looks so bright while green looks... Thank you for the video

Do earth has rings?

So maybe a lack of water is why life is so rare in the universe?

are we atoms?

We got water from Mars, and Moon is water tanker.

Just like the shaft is cooled to produce force in Nuclear Plants. The oort cloud is a possibility of having metals and water in asteroids revolving due to Sun's Gravity so create a spherical band of metal and water. The direction the asteroids in the OORT cloud move, the electromagnetic flux produced by the moving asteroids is stabilized to create a field, that shuns outside Solar System Radiation. That is why water is required.

Best use of a tattoo? I think so.

This channel should have more subscribers and viewer than Mr beast

I missed the first 20 minutes. Weren’t you supposed to send a link before the program started? Never got one. I had to do an exploration to find this. I will never leave a donation again!

:)

Sorry to say that about the space water , when the creation of the earth God separate half of the water on Earth and the half to up side and the middle place is called space see Bible (Genesis 1: 1-8) this is made on second day here the earth is having water but the upper water , the earth is made by 24 hours 12 hours day and 12 hours night but to know sky water actually while creation God added.2 more means 3 planets or something like this that these are the numbers 10 and 12 for 10 is 25 or 55 and 12 is 26 as 66 each one is having the separate meaning and to tell about 10 and 12 called J and L means in Indian language water and normally where the water there must be fish so 25 is as 55 and 26 is called 12 here 5 5 12 called EEL the name of the fish the secret is after number 10 the next number is 11 and 12 is as in neumaralagi 1 is A so 10 11 12 as J AA L means in Indian language Hindi meaning net the fishing net so we must know that there is water and normally the place is called God place where God is sitting on the 11 the number is invisible the size is as each one is the length is 18 and the width 12 as each 29 and 26 as called 1290 and 1260 and 1290 1260 as 49 is 9999 =36 and 46 is 6666= 24 as the same earth measurements and each number that is 11 is having the name called Jehovah and Boez means Jesus Christ see Bible ( 1Kings 7::15) and right side J left side L the Jesus Christ and the Lucifer sitting so this is called the thrown of God and the Earth is God's threshold hold thanks

Uranus is the Greek god of the sky.

Why can't i have my own planet ?

U know it real when she has the solar system tatted on

Not showing us the images you are talking about really sucks

Very cool. Not sure it's $12B cool, but it's cool.

If water is so important why are we allowing Fukushima Japan to dump nuclear waste into Ocean?

Brian is not looking well. Hope he is in good health.

Doggonit. Missed the first 20 minutes.

Do you people have any idea how list you sound?

I hope he got some sleep.

Great talk, but a really bad guess on distance to Formalhaut. It the 174th closest star to earth at 25 light years, not _“10,000 ly. I think”._ Hard won lesson: “I don’t know” is a much better answer than a bad guess. She should have gotten _”I don’t recall the exact distance, but it’s one of the nearest stars.”_

The notion of life needing water on planets where liquid diamond rains, in wildly different environments than Earth seems biased and unscientific.

That voice is simply too much for my misophonia , sorry

A few things. She keeps saying dust ice clouds? Those all are biological processes. Dust is organic, ice is frozen liquid water or transition metal, and clouds of particles? 4 seasons ? You only need four season if you have a plant cycle or something similar. Also she says they have to proint the telescope at a Star first to the capture an image of Neptune/Uranus.. lol. The truth is all between the lines and poor use of words as descriptions. In or outside the lexicon of Astrophysics and Asto-Bio-Chemistry.

hey - take it easy science.. i'm losing followers -(insert religion here)

So mch $ And So Long To Create@JW🛰 and a half million km's away ONLY in a infinite universe..I Have More Faith in Voyager loll😭🙌🏼💫

She openly admits that they withhold data and pictures from the public. Pretty annoying.

What are you gonna do with advising and comment go to squeeze it out of the comment and drink it?
