I am from India. Love the way you explain so simply. Have always learnt so much from your lectures. God bless you and do continue to teach your global students
Congratulations (from Norway) Andrea with the noble prize in physics. It makes good to see you are glad scientist who celebrate your insights and discoveries. It is amazing to see how the stars moves in the center of our galaxy.
Hello Dr. Greene!Thank you for sharing and connecting us to those wonderful minds.Hopefully Roger Penrose will be your next host!Greetings from Greece 🇬🇷
Wonderfull to sea Dr Andrea talking so lightly on very complex ideas.Thank you, Dr Greene, for letting it happen.
Thanks Andrea & thank you Brian for making this possible!
Andrea Ghez' enthusiasm is infectious, thank you so much for getting her on the show. It was a real treat to hear from her since her award.
Regarding requests for the show, yes, Penrose would be great! Is it possible to maybe catch up Leonard Suskind? I would "love" to virtually pick his brain to get caught up to where his current line of thinking is at with regards to just about everything he has spoken and taught about in the past. I'm sure the conversation you could possibly have with him would be absolutely engaging, as it always is with him.
Brian Greene is a hero. Making the most complex ideas in Science accessible to all is such an incredibly generous give back to all of us who do something else for a living. Thank you to you and your colleagues.
He’s not a hero, a VETERAN IS A HERO, NOT BRIAN GREENE. See there’s a lot of people that have no clue what a hero is.
It’s heroic to kill children and women? To kill innocent civilians? There is nothing heroic about war pal
Brian Greene you are a great teacher, like a Richard Feynman! Your passion oozes in your simple explanations to the laypeople too 🙏
@p d you call it ego, I call it confidence 🤷🏽♂️ which tbf is a very fine line, but personally I find Brian Greene a very entertaining teacher like Feynman. To each their own!
Thanks for talking to Andrea Ghez! And yes; Andy Stromiger would be a wonderful guest for your program! Mike Brown is also a great idea.
I saw Dr. Andrea Ghez on a NOVA documentary about the super massive black hole in the center of our galaxy a number of years ago and was marveled at her work and intuition. Congratulations on this achievement.👏🏻😅
Thank you Dr. Greene. This was very enjoyable. I hope you do more, because your shows and books inspire and drive thoughts and ideas of many people, that we might advance sooner. I believe that even a novice can help us advance by just asking the right question. I think a lay person is sometimes better equipped to think of the unthinkable. Imagine.
Extremely interesting! Andrea Ghez is dynamite.
Andrea Ghez is a total badass, scientifically speaking of course
She's a badass in every way.
That was great! Thank you professor.
Greetings from Sweden - impressive work - thanks 🙏
At 1:12:00 . Thanks for remembering my question from last week about Quantum entangled particles and what would happen if one goes in a black hole. Looking up firewalls for black holes has been fun. And to have a Nobel prize-winning scientist discuss a little more on the subject has been priceless. Sincerely thank you. You guys are Food For Thought in these starving times.
I majored in physics and I’m trying to get my daughter into the sheer joy of exploring these equations. Andrea Ghez is a perfect example for her. I’m sure she will get a lot from seeing this video. Thx for posting this Dr. Greene!
My family and I voted for science today!

Great chat guys. The first time I saw the animation of the orbits of the stars at the centre of our galaxy it was amazing. Congratulations on the research which produced this.
It would be wonderful & exciting to see Prof Greene interviewing Sir Roger (if that happens). Apart from his 60’s paper on singularity for which he was credited the Nobel prize would also be great to know Sir Roger’s views on his CCC theory given that there have been some observational evidence recently.
Thank you for putting out this great science content.
I heard it being talked about on Dr. Becky's (astrophysicist) youtube channel and the expert she interviewed said Venusian ocean like it's an everyday word; it sounded so weird to me, I said it the whole day. Love your work ;)
Thank you. Congratulation to Andrea Ghez for her upcoming Nobel prize.
Video bombed by a squirrel! Always quality, thanks Brian and Andrea.
In love with Professor Ghez!!
Thank you so much Brian Greene
Andrea apparently doesn't work a single day in her life. She is absolutely in love with her research. She leaves a trail of WOW when she speaks. What a great gal.
what a great conversation of between a remarkable man and a remarkable woman, thank you so much!
Thank you very much sir.
I would like to hear from Michael Brown and his search for planet 9. He would be a great guest.
I too want to become Physicist and Mathematician as I love Mathematics (even though I am bad at Mathematics)
do it. math can be learned.
Greetings from Spain
Brian Greene sir you are amazing I am a very big fan of you .
Mr. Brian You are great man!
Superb.
love you both
One more awesome video👍
I like you and your channel a lot, I am frustrated as someone who lives in the catskill mountains, it seems all the housing is going to city people for their second homes, and therefore there are little affordable housing solutions for locals in the catskill mountain region... If you are spending so much time in upstate NY please make a job or two for a local... Thanks
Thank you Dr. Greene .. Wave to Archimedes of Syracuse .. Galileo Pendulums onto .. Amazing!! Amazing Gap in history .. 2020 Nobel Female Laureate Andrea Ghez shows the Einstein INCH equation, graphically.
Brian Greene for president!!
A massive star going 7.000 kilometers in 1 second? try to imagine it. Its just incredible and unbelievable. Its probably just that we are so small that its uncomprehensible for us.
It is good to see brian
Great! 👏🏾👏🏾👏🏾👏🏾
Question for Dr Ghez: On using your old equipment and new to align to the same coordinates as being a tricky problem (59:22 for about 2 minutes). Do you have perhaps an envelope of the elliptical orbit of SO2? Much like a trumpet narrowing down as it gets closer to the mouth, so too would the initial envelope be larger than the ones 25 years later with the more sensitive equipment.
Reading is fundamental, Brian....and so is mass !
Question: Why would a black hole ever be able to evaporate? Would the Schwarzschild radius stay intact all the way down? Why does it remain infinitely dense to 0? Is there a point as it's losing mass where chemistry starts to happen again?? Or does it maintain a dense soup bubble to 0?
I just loved the introduction.🎼🎶 I've started World Science University. Thank you so much, it's a fantastic opportunity for everyone worldwide to study free online.
W.Hugh Woodin and Edward Witten would be great quest's.
Congratulations Professor Ghez for winning the Nobel Prize. So exciting !
Only if I had a teacher like him I would have been so much good in physics.
That's great. Go ahead girl and rock the world.
@Caishen Salelius 6022 right
Who was the Scientist who found the mechanism for which a black hole could physically form? They along with Schwarzschild deserve the Nobel.
Question: How/if will the evolution of quantum computers and A.I. (perhaps combined?) affect the development of verifying String Theory via new experimentation?
Physics for poets!
Lovely person
I don’t know anything about math. But I wish I did. Listening to Brian Green makes me wonder if when I take shrums , we can see the universe in the same light.
Hey do you guys have a beginners 101 series on physics anywhere or recommend a good one ?
How about reading a book?
You know, one made of paper
@@eglintonflats feel free to drop a recommendation of a good cheap one; however books are little bit too directed towards ''fiat minds'' if you will ;)
Congratulations Andrea.
Thank you Brian.
Dear Prof Greene, If space time is quantized into local 3D units in the scale of Planck's length ,than how do we refer to the new non local space which separates these units apart from one another? how do these units communicate between them?
can we assume that this extra space is a grid like non local extra dimension ( or even dimensions)? can this non local grid like dimension be responsible to the "spooky" quantum behavior ,like quantum tunneling or quantum entanglement?
Thanks, Eran Sinbar, Israel
What happens to time if we go through a black hole?
Professor Ghez - you make a good point that Einstein’s gravity theory is not the final answer. There is a fundamental problem in that it is irreconcilable with quantum mechanics. There is also the problem of basic Newtonian gravity theory, which is why science is searching for the elusive ‘dark matter’, which is reputed to make up ~84% of all matter of the universe.
There is an alternative point of view which hasn’t been philosophically explored by science: that Newton’s imagery and equation were fundamentally wrong from the very beginning. It’s possible that a nucleic density matter exists at the centre of the Earth, which is very different from objects we find on the surface. This idea would negate the need for ‘dark matter’, because the extra gravitational effect comes from within the heavenly bodies themselves.
This strong gravitational interaction from core to core can even explain climate change as an alternative to greenhouse warming. If a stronger gravitational force exists on the orbital plane, giving the solar system it’s generally flat shape, then extra tidal energy could be transporting heat away from the equator, giving the effect of global warming. This would happen because the Earth is spending more time on the disk shape of the solar system.
What percentage chance do you give this new idea as being a true picture of reality?
When he said Donald Trump has proved the Reimann Hypothesis and found a new way to quantize gravity, everything just went faint in front of my eyes.
Thanx WSF for the greate persons you bring in and the place to share ideas. - Congratulations Andrea wishyou the best. - Hexagonals are the BEST of all figures to fill space with and actually matter tends to fall in hexagonals throug space just see when zooming in though a super-nova star. - Have you notice that stars do not follow same direction orbit? they just go in all directions.
Why do not stars collapse into one another even they get too close near the black hole? even stars follow different orbits they just dont collide into one another. - We see that most purple stars speed up at the black hole spot no matter to what side they orbit(left, right, down or up. - there is an orange star that speeds up VERY FAR AWAY from the black hole spot so why is that? even this orange star seems to go faster for about half the orbit and slower the other half.
My self think that it might turn out that instead of a BH inside our galaxie center it could be STREAM of LIGHT-MATTER as we have seen some other galaxies do the same, it looks more like an OUT PUT of light- matter due that the orange star mentioned up above speeds up way out to high from the BH spot, galaxies do EMITE an out put perpendicular to the galaxie disk why should our galaxie be an exeption?
Galaxies just might work the same as the Torpedo fish, if you see the video: SHOCK AND AWE: THE STORY OF ELECTRICITY-JIM-AL-KHALILI-BBC HORIZON in you tube, at time 30:10 we see the left side of the Torpedo fish that shows a grouping of electric cells that all cells must to be interconnected one to the other so at the end all the cells as a single group will give an out put of 120 VOLTS, at time 30:21 the right side is shown and same as the left group all of them are interconected one to the other so they are able to give an output of 120 volts so when this 2 groups meet they produce a 240 volts output tha would nock down a grown person, this same video at time 30:34 the fish shows a kind of a circle that to the bottom part forms a V SHAPE, this v shape is very common in galaxies just see the video:
WAL-THORNHILL: NO ISLAND IN OUR ELECTRIC UNIVERSE - SPACE NEWS in you tube at time 3:20 left figure, the black middle part of the galaxie shows to the bottom the very same figure as that in the Torpedo fish, if you click my logo and see the video THE FLOWER OF LIFE OR DNA DECODED you will see that the picture of DNA shown in there has 2 V shapes one at the south and one to the north, same thing is seen in the Aztecs SUN CALLENDAR to the south and to the north as well.
The DNA FIGURE shows that the DNA SYSTEM divides by 2 sides that are north and south sides, it shows entanglement in cross section from north to south while all pairs entangled meet at the very middle part of the sphere which makes me think that even stars entangle by pairs and all the entangled stars make the WHITE SPHERE that is been seen in our galaxie that is the place from where the out put of the galaxie come from to the north a stream and to the south another stream of light-matter, this output is channeled through a V shape(one to the south and one to the north) the v shape must to start by the white sphere center and this out put is directed up both sides though this V shape electromagnetic kind of round tunel and my thinking is that this tunnels is what distorts matter when seen say a galaxie from inside of one of this tunels making it look like what they call GRAVITATIONAL LENSE but really it might be a ditortion due that we are seen from inside an electromagnetism that is kind of round from the inside.
Thank you my teacher from Los Angeles . Last century from planet Earth was got signals from Venus . ?...🙏🌻🌻🌻🌻🌻
I'm dead. That troll @zeroskull, stop being toxic! We love you BG!
27:54 She joins.
Do I see collisions of The Stars near black Hole? This looks like some Stars accelerate whan are near to each other.
I am so glad, dear fancy woman, You got Nobel Price.
Could you invite Jim Al-Khalili please .
How can I obtain my bio bank records from the late 1950s when I was temporarily an orphan?
Thank you
Can we consider that solar system is free fall system based on the outer space is weightless?
If you mean the solar system is in free fall around the galaxy, yes.
Free fall is defined as gravity being the only relevant force acting on a system.
Can i ask u something?
A talk with jordan peterson would be awesome!
Thanks for joining us, thanks for joining us, thanks for joining us. Ahh Brian, enough, let her go.
If black holes suck everything in, why aren't the planets going in, since we are saying the planets are affected by black holes?
Do you understand the concept of distance?
Sir Roger Penrose creates beautiful drawings displayed by overhead project.
I missed it
Since there're Billions of Stars in Milky Way Incl Sagittarius A Black Hole, AND there are ~100 Billion Milky Way's in the Universe with their Sagittarius A's, WHY DO WE NEED TO SEARCH FOR BLACK HOLES?
Is called infinity dimensions
Since Venus was a Roman Goddess, the correct way of calling Venus's inhabitants should be Venusians
following the Latin grammar of course

Speed of light is speed of causality hence why its represented by c
The c is actually from _celeritas._
Nope sorry its causality I have a physics degree. Causality is the fundamental speed limit in space time, hence why gravity, photons, gluons (all mass less particles) travel at but can't exceed 300 000km per second. Cause and affect fundamentally can't travel any faster IN space-time
Great ,bright students ending up in the military and financial industry , how useful .
Not "useful".. VITAL if you value your "way of life". Surprisingly Peter...other nations are not the USA and in a very real matter of definition are enemies. Our enemies use ALL their resources. As a citizen and a tax-payer...I DEMAND this of the USA. The world is not the 60s "Age of Aquarius".
the universe i have a question
24:10 you used humans as an example we eat and become bigger. humans also use the restroom. does the black hole also go to the restroom (white hole)? is it real? has anyone ever seen a white hole?
Dark Matter is not made by BH as i supposed, this has been confirmed ??? because talking about DM changing the orbit of stars orbiting a MBH is a confirmation
You ever seen a perfect spherical polished diamond?
Singularity ? - your fellow Nobel prize winner Roger Penrose won exactly for predicting their inevitability...known as the Penrose Singularity Theorem !
Will 10 stellar mass and 100 stellar mass make the same singularity
In my opinion it's a big problem that our brightest minds have to go work in the military and/or financial system. Instead of helping society they are actively helping to destroy it.
lol. its a big problem our "brightest" (despite them apparently getting deluded virtually to 100% degrees by looking at academia, by blatant hoax of trump derrangement syndromes and climate change) minds have to go and find out mostly nonsensical information about things that have no relevance
People from Venus are called Venuses.
Rhymes with "penises".

Could dark matter be from a near by universe
Gosh, that visual of how black holes would look if it were happening in front of us wasn't impressive at all. Especially the part where the visual jumps from supernova to black hole. It just skipped a whole huge chunk of the visual process.
Another thing that makes me suspicious of our so called knowledge is the fact that they never show us a 3D representation of mass bending space. It's always just 2D. Like if a heavy ball were to lay on a rubber sheet. It drives me nuts!!! Why won't they ever show us a 3D model??? I think either because they are lying so we can't figure out free energy or we are not as knowledgeable as we think.
I mean we have been visited by "flying saucers" and orbs and such since the beginning yet "nothing" could pass the speed of light???
I'm so sick of the lies and I'm so glad I haven't had any children to have to deal with this. Our freaking leaders are evil greedy pedophiles that actually want their children to finish selling the oil way after they have died.
I can't STAND IT!!!!!!!!!!! WILL SOMEONE DO SOMETHING!!!! OH LET ME GUESS. WHY DONT I DO IT????? WELL MAYBE YOU'RE RIGHT.
Ve-nu-tian. And not only is there life on every planet in the solar system. There's intelligent life on every planet and every planet is alive and so is the Sun. Next Question!
