Watched this Ted Talk about 2 years ago. I had dropped out of highschool with only 5 subjects left to graduate and did not know what I wanted to do with my life. I was depressed and family issues were taking the best of me. Took me long enough but this year I'll be finishing high school and going to college to get a degree in Astronomy and could not be more excited for my future. I will always be greatful to Andrea for being so passionate about astrophysics, and for showing me what my passion is. Thank you, thank you, thank you❤
@@gayaquinn7177 Thank you for checking in! Had issues in the middle but finally was able to start college this year (yes, this year out of all them haha) and has been quite tough but taking it slow and enjoying the process. Right now attending only 2 subjects but doing well and getting good grades so I'm happy. Online lessons have been horrible though, so mainly being self-thought at the moment. Thankfully I speak english so I have waaaay more books available (my native tongue is spanish and specifically in my country, Uruguay, Astronomy books are really hard to find). Thank you all for the good thoughts, I appreciate it a lot💞
So I've met this professor - she is a genius, as well as a very nice person. Plus now it is clear that she also has great public speaking skills. Quite a combination if you ask me!
I was looking at her speak for the first few seconds and I was like "man, she's nervous". Then they showed the crowd. Anyone would be nervous with that massive crowd. That being said, good lecture. It reminds me of my astro physics professor. Crazy old man.
She was fun to listen to. Half the time when you listen to these sorts of people they put you to sleep, even if you're interested in what they have to say. I'd love to listen to more of what she has to say. Not to mention I'd love to hear how she'd teach children about her field! She'd enthral them!
This amazes me...especially those stars orbiting around something....obviously not visable. I wish I could start over again and spend my life doing something like this. All of the people that talk at TED obviously look forward to going to work everyday.
I watched her shared her observations using the Keck telescope in Hawaii to catch the supermassive black hole, and I marvelled on her genius. I am so glad she won the Nobel prize for physics!
I am bothered by people who make mean-spirited negative comments like so many of those below. It's just so easy - takes no skill, no risk, no courage to sit back in a chair and take pot shots at others. Those of you with something negative to say: I suggest that you try getting up in front of an audience and giving a lecture yourself. Next time you might not be so quick to criticize. I lecture it for a living and trust me, it's not easy.
The most accurate way to prove them is to look at stars moving very fast around those black holes ( so their orbits are very small). That can't be done in other galaxies, since they are too far away, so astronomers can't resolve individual stars orbiting these black holes. So my guess is that we can understand a fraction of the super-massive black holes (the ones in a diet) by understanding our own Milky-Way's and then comparing some of the stuff we learned with similar galaxies.
She wasn't thinking on nerds that have time to surf the net and self-educate themselves. She was speaking to other TED people who work every-day almost 24/7, who have very little time to learn by themselves, although they are very, very smart, so they just need a compressed talk to get most of it. There are 2 kinds of nerds in this world, those one who know how to put that nerd-ism to work and produce something, and those who don't.
Well but that's the whole point of her discussion which is that the supermassive black hole causes the super gravitational well. Although now that you mention it the pull would be more funnel shaped as opposed to a flat plain. Also what's more puzzling is that her time lapse photos show galaxies rotating randomly as though the blackhole's gravity had no effect. Andrea if you're rading this you can chime in anytime!
I actually did.. I love her work and I love physics and science in general especially einstein's work and tesla ... I never said I'm muslim nor did I bring up religion I commented on a scientist whom I love yet you come here with your prejudice and start speaking about quran and mohammed ... I hope you open your mind and stop judging people and actually learn what your talking about before speaking
@SkunkHunt Sir, by definition, we can't see them. However we can make concordant observations which show in fact that something which almost exactly replicates what one would expect if there was a black hole there. For example, if you examine the velocities of stars in-falling in the center of the Milky Way, their trajectories can only be explained by there being an invisible mass there. Given their velocities, we can calculate that the missing object is *most likely* a black hole.
I believe that black holes 'save' information that led to the formation and development of each galaxy, to 'update' subsequent the universe, maybe in the same way the human genetic information is transmitted from one generation to the next. They also seem to control how much a galaxy can expand in space. I read that low mass, high metal stars may provide the best chances for locating rocky planets. So it seems that there is a ’pattern’ already identified out in space. Maybe each galaxy has a 'DNA’ .
congrats 🥳 to Ms Andrea Ghez for her great discovery about black holes 🙏🏼 I m too a cosmology enthusiast and one day me too giving humanity a great discovery and innovation in the field of space science ✨🔥💫🌟
Just wish Andrea Ghez herself can answer this. Is there such a thing as a galactic equator, in which the gravitational pull is on a razor thin plain and it affects everything in it's path? If so could it affect the solar system like say around the year, 2012 for example?
so if it is a negatively charged mass it will attract positively charged masses such as light and most matter, but as the matter nears the actual black hole to becomes either entangled in its torsion/spin field or broken apart by it depending how near it gets. this process would create an environment catalytic to star creation do to the abundance of the available necessary material. like how we create man made diamonds.
Black holes are decribed as being "without hair" since nothing can escape them, they're very simple to describe, and yes, they are very much like elementary particles.
The Swarzschild Radius is proportional to the mass of the object it is describing, a function of the gravitic potential of that object. A supernova is a star without enough mass to form a black hole, thus it cannot compress its contents to within the swarzschild radius and cannot form a black hole. A supermassive star with enough mass to form a black hole is able to compress it's atoms to within their neutron degeneracy limits...which is amazing...and within the radius, to make a black hole.
As soon as she said that they believe that a supermassive black hole exists at the center of our galaxy, I was scared. I expected at ny second for everything to be sucked into it, and our existence would be over. That's kinda cool. Would we even feel the effect?
Exactly the problem I was pointing out. If I was to make a theory regarding black holes and enough people believed it, it would be considered "fact". I'm not disagreeing with the women giving the presentation, I think her theory is quite sound, I am just pointing out how we will never truely have "facts" in physics. She said so herself, "How can we prove that something is there that we can't see?". There could be other explanations for the "hot spots" in the universe...
Nothing, no one in the world can give me goosebumps or I can be jealous of like physicians They just make everyone else seem so stupid even if you're a doctor Physics is a passion And I love it sooo much
11 years before she said she had been doing this for 15 years and now she got the Nobel prize in 2020. Which states she had sacrificed half of her lifetime for this.
If I had to speak in front of an audience the way tedtalks folks do, I'd swallow my own tongue with nerves. I was thinking that cos she's the only tedtalks person I saw who seems pretty nervous.
+Raphe That is a very good question. I'd think that it would be the outermost perimeter of the asymmetric universal expansion "field" (for lack of a better term). Unless gravity can influence other universes and if said universes exist, both of which open some very wriggly cans of worms.
***** That make sense, too, given that we cannot peer at objects deeper into the past than that. Kind of sad, really, that despite our advances in technology present and future, we will not be able to see any further than 13.7 billion years from the time we last looked.
Raphe- This is the biggest scientific debacle ever, Because many Quantum mechanical principles are ignored, nature abhors the formation of black holes!
maybe the young stars are evidence that black holes really are worm holes too; when an aging star gets sucked into it, a duplicate baby is then warped out of another black hole somewhere else, being refreshed, transmuted and duplicated, the old star stays in the massive center, the new star is born somewhere else... just my crazy imagination theory
so when a super massive star(witch should have a system of orbiting objects) collapses perhaps to the necessary range it continues in a symmetrical manner by becoming inside out. meaning a quasar, i believe, with light and protons being ejected leaving an immensely dense and incredibly negatively charged anomaly(possibly all electrons). this theory makes speculation on galaxies as electrical systems much easier to fathom. all truths should be self evident.
So today she won noble prize for this!
She did it. I'm crying for her, so happy.
Yeah, that's why we are here to watch this video 😑

Genius was officially confirmed today
Yippee
Does she do as much meth in everyday life as she did before giving this TED Talk?
11 years fast forward she got Nobel prize
I love how excited she seemed about this project - it's too few people that love their jobs as much as she does, I think.

She's such a science nerd! I love it! :)
Wow it has been ten years
Congratulations on winning the Nobel Prize in Physics 2020!
She just won the Nobel Prize in Physics! 😊

Congratulations to Andrea for a well deserved recognition of her contribution.
She reached her goal after years of hard work. She is a proof that hard work pays off
Congratulations 2020 Nobel Laureate Dr. Ghez!
Also, at 13:30 she shows a baby being torn apart by a black hole.
She was already a superstar 10 years ago!
10 years later congratulations Andrea!
Amazing how she explains so much, so clearly, in such little time
Congrats Prof. Andrea Ghez. For the 2020 Nobel prize in physics ❤️

Cute and brilliant, I have never heard astrophysics explained with so much gusto
Thanks Mam 🙂
You're really inspiration for many students 🤓
Gah. I gave it 5 stars for fascinating subject and great content.
Yeah she got more than 5 stars 2 weeks ago
Omg she won the nobel prize for this just now
I watched her shared her observations using the Keck telescope in Hawaii to catch the supermassive black hole, and I marvelled on her genius. I am so glad she won the Nobel prize for physics!
A decade later Professor Ghez PROVED Sagittarius A is the location of the galaxy’s supermassive black hole.

I agree. A little off topic, but I attended one of your lectures on medicine when I was in high school, over a decade ago. I was so moved!
Yeah no one can complain now that she won the Nobel Prize
You can tell Prof. Ghez is very excited about this fascinating subject. Congratulations on wining the 2020 Noble prize!

gotta love those diagrams of stars orbiting, and also her general bounceyness.

Being part of these "Black Holes Hunters" is just amazing, I feel like a science fiction character.

She did very well for such a long presentation. It would be tough to condense your work so much. And it's not like she is a professional speaker.
Amazing
Thank you for leading the way-
