If your graduate students are in hawaii and you're at a conference...let me assure you that even if they are looking at the stars...they aren't doing that through two lenses...
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.
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!
@musicmakerj1234 I hadn't intended any direct insult, and I am surely appreciative. I simply wish that there were more beautiful women who are also intelligent.
Black holes don't exist. See my video. If you have evidence send it to me... otherwise I'm not interest in counter-arguments with no facts to back up. Here's your problem... NO ONE HAS EVER PROVEN BLACK HOLES TO EXIST EVER.!!! Good luck trying to TELL people they exist when they KNOW BETTER THAN THAT. Black holes never existed and I challenge anybody to send me evidence otherwise you just have NO BALLS and are DOG FACED LYING to people. Good luck with the black hole lie!
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.
@SkunkHunt You are cruel. You know scientist get aroused by their ideas. Then they do their business. Way take this away from them. Black Hole porn is a valid human obsession. Most science has the same obsession with unknowable lust. Like a cult or religion let them have their release! Jissum is jussum Let it go. Unless you get off on always being right, then go for it.
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.
@unou12die: Dude, photons don't have a charge. And the electromagnetic properties of a black hole is attributable to the way it drags space surrounding it (including nearby matter). But, if isolated, a black hole can have no charge.
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.
my obsession... i actually believe the problem is how we think black holes form. i think it is not a gravity process but an electromagnetic phenomenon who's probability increases with mass. if gravity is a product of inertia created by the torsion/spin field of a governing body and the directional attraction of electromagnetic entanglement space could be far less complicated and the charge of unique matter becomes very relevant. continued on next post...
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.
Andrea Ghez is one of my fav scientists :) and i like how some people have negative comments to someone who is a lot smarter than you are!! be tankful you learn something you didn't know be for and have some respect for people that work hard to tell people like you.
This comment has received too many negative votesshow
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?
Do you believe that our Sun has gravitational forces which act only in a plane? What about our planet? If the galaxy had a planar force acting which could act on the edges of the galaxy (remember the Earth is on a galactic arm), then wouldn't we see the effects of it as it swept though stars on its path to here?
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!
The Mayan predictions are unfounded. Those formally trained who actually study the Mayan's will point out that the Mayans predicted no such thing.
Further, predicted the white man's arrival is problematic as many tribes have fears of others and often refer to other tribes as lighter or darker skined (not all Native Americans have the same skin tone). Lastly, the prediction itself was incorrect since a group of lighter skinned people arrived and not a single individual.
@dctrex That's just silly nonsense. Gravity does not propagate in planes. Its effect does not vary enormously in short time scales. Anything to do with 2012 is absurd gibberish.
Well, sort of... out solar system, and almost all others in the Milky Way are on the "galactic equator", the disc of gravitational bias around Sgt A*. This is what gives spiral type galaxies their distinctive shape.
This is not material for a catastrophe, however, we have always been on the galactic equator. Our impeding collision with Andromeda should shake things up nicely, but it won't happen until long after 2012!
Using special relativity, couldn't you show that the reason there are young stars near the the black hole is because they are moving faster and therfore moving through time slower.
Because it's in the centre of our galaxy which cant be seen or photographed from where we are (or from where Hubble is). There are others in the centres of other galaxies also. They are surrounded by such intense light and radiation that they are extremely difficult to detect.
This comment has received too many negative votesshow
You use derogatory language to deride and obscure a very important point; correcting for atmospheric distortion from the ground is an extremely cost effective way of getting observations that would otherwise require expensive space programs. Space has its place, but it is so much more expensive to get there and operate from there.

You can't see the center of our Galaxy in the optical; too much dust in the way. At infrared wavelengths, where you can see through the dust to the center, Hubble has less spatial resolution (because of its smaller mirror). HST is just not competitive for this research.
I understand what she is saying fine. Your argument honestly makes no sense, unless confident, extroverted people really do act this way where you come from.
She talks about the Schwarzschild radius - why does this exist? Simply by compressing matter beyond this radius wouldnt neccessarily result in a black hole. And if it does - why? Why does gravity win out to compress something beyind its limits? ie; why are there supernovas and there are black holes. Whats the key difference?
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.
Firstly - is the size of a black hole defined at its creation? ie; feeding more and more matter into it shouldnt make it bigger? Secondly - their calculations are based on newtonian physics. What if a black hole "ignores" newtonian physics? Their calculations would be all wrong. ??
Newtonian Physics works just fine, when we employ it in certain size scales. In the middling world of planets and stars, humans and mountains, it works perfectly and without aberration.
When we look to the supersmall, on the order of the quantum, different rules take over, as particles can actually jump point to point with no distance traveled/time spent, and can come into existence at random. The quantum world has its own sets of rules, that we're still barely capable of comprehending.
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!
I think its been shown now that you can get an object down below its schwarzchild radius without it necessarily collapsing to a singularity. Resulting in a black hole with finite dimensions. Can anyone confirm this, i forget where i heard it.
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
Andrea Mia Ghez is an astronomer and professor in the Department of Physics and Astronomy at UCLA.[2] She received a BS in physics from the Massachusetts Institute of Technology in 1987 and her Ph.D. at the California Institute of Technology in 1992.[3] In 2004, Discover magazine listed Andrea as one of the top 20 scientists in the United States who have shown a high degree of understanding in their respective fields
people comment on her cadence because they lack the smarts to comment on the substance. they're the type who can only talk about the weather when in a museum.
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.
About her speaking: Some of these guys who posted before are rude and ignorant but I agree that she needs to speak a lot more naturally, I am sorry but it is a little annoying.
punkotek: No, we are orbiting it but not 'inside' it. There is a big difference between having a house in the beach and t be a fish living in the Ocean bottom.
omg I'm sooo glad I'm not married to this woman, (she's probably equally glad she's not married to me!!) I'd just have to gag her!
I'd love to get to the end of this presentation, but I just can't!!! She sounds like she's "trying" to be interesting to a class of 4yr olds, and failing miserably.
@666norton420 I can't understand you, she is at TED so what? You all forget TED is not for the experts only. It is for non-experts who might want to switch into fields they've never heard of before.
hehe :) She seems extremely ecstatic to be speaking about her study (which is really great!) but it also seems she is a bit nervous, especially at the beginning of the presentation. I enjoyed it :) Sometimes we don't look beyond the presentation :p
She doesn't pause to breathe. Actually, she deals with that pretty well, probably from giving regular lectures (say, at a university), but it's a common sign that's she's nervous, and it tends to make listeners uncomfortable.
Response: If the old stars have been absorbed, which were far more massive, the young stars should have been absorbed a long time ago aswell... right?
Not necessarily, unless I don't get your point. The longer the stars remain there, the longer they've had te chance to get absorbed. And are older stars always more massive than younger stars?
Well, young stars would first have to be formed by clouds of gas and debris to come to existence as explained in the video. So any old star would be more massive than a gas cloud. Unless the star has strayed from it's regular path and somehow randomly ended up in that part of the galaxy? :P But that also sounds improbable. So what they're trying to explain is how stars can form in that region. Because it is kinda self-contradicting that they exist there.
Sure, but young stars are still several millions of years old. That's more than enough time to get to centre of the universe from a somewhat more distant place where they could have formed, isn't it?
I too found her difficult to listen to...her inflections and mannerisms made it feel as though she was speaking to elementary school students. That being said.... this was a fascinating talk.
How long does it takes our sun to orbit this supermassive blackhole at the center of the milky way? Its a marval how celestial objects move about another. We realize our earths movement through the sunrise and sunset each day, but it's neat to be conscious of our further movement throught the cosmos as we follow our non-stationary sun.
If your graduate students are in hawaii and you're at a conference...let me assure you that even if they are looking at the stars...they aren't doing that through two lenses...

About her speaking: Some of these guys who posted before are rude and ignorant but I agree that she needs to speak a lot more naturally, I am sorry but it is a little annoying.
punkotek: No, we are orbiting it but not 'inside' it. There is a big difference between having a house in the beach and t be a fish living in the Ocean bottom.

omg I'm sooo glad I'm not married to this woman, (she's probably equally glad she's not married to me!!) I'd just have to gag her!
I'd love to get to the end of this presentation, but I just can't!!! She sounds like she's "trying" to be interesting to a class of 4yr olds, and failing miserably.

does she not know she's at TED?
it's already interesting... talk like a scientist and explain it already!

@666norton420 I can't understand you, she is at TED so what? You all forget TED is not for the experts only. It is for non-experts who might want to switch into fields they've never heard of before.

"I can't understand you, she is at TED so what? "
so, it's not kindergarten.
the audience and most listeners aren't bible thumping retards.... she can just talk and we'll get it.
there's explaining things and there's explaining things as if everyone in the room has the IQ of a rock.
too much indeed.
;d

She might explain everything a bit too much, but I actually learned a few things I didn't know. I am grateful for that.

I think her voice sounds like this because of her nervousness, but if you get over this it's a great presentation about a very interesting topic.

hehe :) She seems extremely ecstatic to be speaking about her study (which is really great!) but it also seems she is a bit nervous, especially at the beginning of the presentation. I enjoyed it :) Sometimes we don't look beyond the presentation :p

I'm sure that she is quite competent and intelligent but her delivery is very distracting. A little less kindergarten teacher please.

She was so energetic and excited about her study so even that her voice wasn't that of a presenter, I was completely hooked and with her.
I love talks like these! It's wonderful when people have such motivation!

I am under the impression she is quite nervous. Speaking in Public is not for the feint hearted. She did very well considering that fact.

She is used to teaching lectures, and asking for funding. Decades of undergrad lecturing forms habits.
Seems like a good prof to have, 'cause you'd never need to go to her lectures.

Crazee108 2 years ago 4
She doesn't pause to breathe. Actually, she deals with that pretty well, probably from giving regular lectures (say, at a university), but it's a common sign that's she's nervous, and it tends to make listeners uncomfortable.

Interesting although her lecturing style feels a tad be conceited. I liked it anyway.

I'm guessing the old stars are already absorbed by the black hole, so only the younger ones remain... Any thoughts?
Ramsez 2 years ago
but the new ones didn't have the environment necessary to form in the first place.
Phillip1220 2 years ago
@Ramsez no, there'd still be old stars around.
Sovieto 2 years ago
Response: If the old stars have been absorbed, which were far more massive, the young stars should have been absorbed a long time ago aswell... right?
NegatioNZor 2 years ago
Not necessarily, unless I don't get your point. The longer the stars remain there, the longer they've had te chance to get absorbed. And are older stars always more massive than younger stars?
Ramsez 2 years ago
Well, young stars would first have to be formed by clouds of gas and debris to come to existence as explained in the video. So any old star would be more massive than a gas cloud. Unless the star has strayed from it's regular path and somehow randomly ended up in that part of the galaxy? :P But that also sounds improbable. So what they're trying to explain is how stars can form in that region. Because it is kinda self-contradicting that they exist there.
NegatioNZor 2 years ago
Sure, but young stars are still several millions of years old. That's more than enough time to get to centre of the universe from a somewhat more distant place where they could have formed, isn't it?

How long does it takes our sun to orbit this supermassive blackhole at the center of the milky way? Its a marval how celestial objects move about another. We realize our earths movement through the sunrise and sunset each day, but it's neat to be conscious of our further movement throught the cosmos as we follow our non-stationary sun.
