- Black holes are gloriously weird. Formed as the death state of heavy stars, they can be as small as cities or as big as solar systems. Our own Milky Way galaxy is anchored at its center by a black hole four million times the mass of our sun but only 20 sun widths across. The rest of our galaxy could harbor billions of city-sized black holes. There are hundreds of billions of galaxies in the observable universe, each one replete with billions of stellar mass black holes and each one probably the home to one supermassive black hole. Beyond the oddity of black holes, they may play an essential role in sculpting galaxies and the universe on the largest scales. Black holes may have carved a world that we could live in.
Director of Sciences Janna Levin invites Yale professor and astrophysicist Priyamvada Natarajan and the University of Arizona professor and astrophysicist Feryal Özel to question if our very existence is contingent on the shepherding role of black holes in the history of the cosmos.

Astro physics with humour. Really enjoyed. Good intro for novice
im here to make a reaction paper but my brain doesnt want to cooperate (ب_ب)
THE FUCK??!! SAME!!! ahahahhahahahaa
Too bad I dont live in NYC to witness these talks LIVE :-( Fantastic discussion ! Thank you Dr's
I love seeing these brilliant women just effortlessly discussing the cutting edge of physics and cosmology.(while looking quite classy fabulous btw)
Thanks for sharing this video. I have two questions.
1. Light or photon has no mass. How does gravitation attract the massless light?
2. Light is electromagnetic wave. Why can light path not be diverted by electric field and magnetic field???
uneducated guess from 5th grade education to #1, if u mean gravity from black hole, maybe it s not the light so much but space itself that gravity is affecting...??
To me any kind of thing that has shape as we see anlist light must have shape due that we see it even in different tones dont you see the rainbow so if you see it it better have shape and much more it waves so how a thing may wave if is not a thing? how light brake to make the rainbow at 42 degrees if is not a thing ? how can then brake if is not a thing?
Gravity curves the space that light travels in.

Is it not true that atoms(matter) go critical (fusion or fission) with extreme compression? This is how plutonium is "ignited". and the result is a nuclear explosion.
Therefore under the extreme pressures it would follow that the matter in the compressed sphere would explode outward in all directions ,long before a singularity formed which means "Black Holes" can only exist as an impossible extrapolation in scientists minds.
Is this not reasonably true?
If not why, and why would critical mass and explosion be bypassed?
I wonder if an outburst from Sagittarius A* star could cause a distortion in the fabric of spacetime? Is there interaction between blackwholes?
Yes they love each other but my self dont know if they have charge to do so since mass is all gone but what hapens to the charges do they as well dessapire or what?
My suggestion is that not a thing may get out of entanglement cause any mass must be made of atoms and smaller masses so black holes must to be the union of all the entangled stars in a galaxie kind of a gathering or concentration of light at the galaxie mayor center. Take a look to the video ENTANGLEMENT AT ALL SCALES just click my logo to see it.
Excuse me please.... 10:04: Black holes pull light because “light has mass”?!?!
As I see it light is just a state of matter.
@Mike Nolan How could a string do a pull or a psh whan it is all loose? dont see how they would unite to all togather make a thing do you? Who am I to say it but Subir Sarcar say s that even they are hard to imagine much less to be truth and dont take it from me but he is a worker at the north pole and not for fan but for work.
Come on. The astronaut in is not inside the black hole at any point in that 1st simulation. It shows how your view of the stars beyond a black hole gets distorted as you approach the event horizon in a decaying orbit. It ends well before the crossing event. It is accurate in terms of look angles, but not time. It also neglects gravitational redshift. In reality the view fades to black and all you can see is your fellow travellers. But Janna is right. We are most definitely spiralling inwards (towards the Milky Way horizon), not outwards. It's just going to take an infinite amount of time to get there.
Nice dress, Janna.
Ah the 'humour'
Maybe just a big 🌞 ? We all live in a yellow submarine 🙃
Just love that song and the one of America that says, something of the sea that he saw in I guess in a pasage I think is called HORSE WITH OUT A NAME thise song just gives me kind of good fealing in relaxing times.
X port s? E.M.Path.Y
*Burp?
Oh god so much dirty jokes coming in my head
WHY dont you give it a wash Mr bean?
@@SernasHeptaDimesionalSpace there really intrest about black holes
@@damn5940 Never cared for black holes, not till heard that a nobel price goes for Mr. Penrose, Know that the thing goes for him for the math that he used and put some to it to describe some how BH just cant be to me still have not swallow not even e bit as true of such event of singularity of such a thing that whene a star is old and just have no ennergy it would collide in its own that has not even energy to light any more it could be reborne as strong as so much millions of stars power some times even gratter than the power of the galaxie stars its in so how can you eat that like that dont you need more pruff?
How do you explaine the orange star near the BH that speeds up way up and far to the right far from the black hole spot in our galaxie? My guess is that an OUT PUT OF ENERGY-LIGHT STREAM from the galaxie center fits better the frame.
@@SernasHeptaDimesionalSpace it's a joke man
