- This talk was given at a local TEDx event, produced independently of the TED Conferences. Astrophysicist with an interest in
black holes. Back in the UK after a stint with NASA.
A joint Thinking Digital Production with Newcastle University. Sponsored by Newcastle University and supported by Newcastle Science City.
Chris Done grew up wanting to be Spock from Star Trek, so doing a PhD in Astrophysics at Cambridge was living the dream. She worked on theoretical models of the intense high energy X-ray radiation which can be produced when material falls towards a black hole, before it disappears forever below the event horizon. She then moved to the USA, to NASA, Goddard Space Flight Center, and started to work more with observational data from these systems. An unexpected highlight was that she became part of the team doing real time control of an X-ray telescope in the payload bay of the Space Shuttle! She returned to the UK, first to Leicester University and then to Durham, where she became one of the first women to be appointed as a Physics Professor. She now specializes in combining the best current theoretical models of what happens to material falling towards a black hole with the best observational data, working especially with the Japanese Space Agency (JAXA) using their innovative X-ray satellites. So she gets paid to do rocket science, and think about black holes!
About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
My favorite thing is when really smart people in TED videos try to incorporate some stand-up into their talks. I genuinely love it. They're humans, and it's very human to want to make people laugh and feel comfortable. and i love her. go off girl, be psyched about those rockets
I love this woman’s energy. She’s the type to get you excited about anything she’s excited about lol. (Although I’m always interested in anything to do with space!)
I want to learn everything about space, but just recently I made a discovery that shocks me,
The universe is 14 billion years old, I know that, but the furthest galaxy ever discovered GN-z11 is 30 Billion light years away, which means it took 30 billion years for that light to reach our eyes.......but the universe is only 14 Billion years old, that galaxy is older than the universe itself? Are we seeing into another universe?
Chris Done is one of my Physics lecturers at Durham University!! She's so eccentric but so amazing at the same time - the best lecturer on the course, it's a pleasure to be taught Special Relativity and Quantum Mechanics by her.
An entertaining speaker and a nice explanation of what she does.
Currently in a pre-university crisis, and I’m gonna pull a switch from English to science.
So 2yrs later on... Updates?
How's it going so far?
@@anabellafl9742 going good! About to finish my major in Human Evolutionary Biology despite never having studied biology before!
Super congrats!!!!
@@anabellafl9742 Thank! I'm also self-studying chemistry and maths! You really can do anything if you just have the right attitude.
I am from Peru.
really a very clear explanation.
amazing intro to astrophysics, bridges high school knoledge to advanced.
Yep! Science has become just like the creative arts 👌
I like this. She explained it in multiple ways in case anyone didnt understand and i love that.
Thank you for sharing.
I was standing in this room 2 months ago and now I'm seeing it on youtube, kind of cool!
she was great! thanks!
@17: 22 . . . looking Over the Edge . . . we don't Really know what we're doing 100,000 Million stars . . . ,Mind Blowing!!!! Research & Discovery Takes Creativity /HARD WORK . . . thank you, dr chris Done !!!
you're right, we're only
+Josh Traffanstedt beginning to understand.
she is great
Why am i watching this. Im a pro at physics.
What degree do you have?
Thomas mcdipper
Im not a pro, i study physics at uit
i’m trying to learn physics any ideas?
@@jeztergaming6943 think about it like geometry, science, and algebra had a baby, then that baby constantly spews theories
This works for dummies
Source:I am a dummy and now a Professor
Thanks
Yes
Homework does not build understanding because it is not science. All homework is is an unreachable goal. Science is different. Science and the scientific method are ideas which become manifest by using the scientific method to reach goals which people can reach. Some of these goals may seem impossible for most to reach but those can eventually be reached too. But homework is not one of those. Homework is just a waste of time. Good lecture.
Astrophysicists don’t like talking about science. They stick to their pseudoscience and wonder why they’ve never produced one single viable hypothesis in the history of astrophysics, cosmology or astrology, no wonder the flat earthers are wining this debate.

This needs explaining......
Clearly Understandable,even for me!I am 13
stay in school, and stay away from losers. theyll drag you down. no matter how smart you are, those losers have dragged down smarter people, believe me.
@@joshtraffanstedt3326 I’m 14
@@joshtraffanstedt3326 Im completely fascinated by space...... everything about it is mysterious and is worth exploring
same tho ur 18 now but still. i want to be an astronomer it sounds really interesting
the first few minutes is possibly THE most horrendous moments in TED talk history- brutal
David gold coast I AGREE! WHAT AN EMBARRASSMENT
+David gold coast Its not great, but thats actually a brutal comment. Please try to be nicer my man.
my bad! thanx 4 da heads up!musicisbrilliant
It seems that are nice people about despite their lack of liking for the same thing. Is this two CZcamsrs really getting along? ahaha ;)
David gold coast We have to try to be nice. This world is full of ugliness.
Skip to 5:45.
+John Murray Thanks!
cheers that was painfull
I read this comment when I was at 5:40. You saved me five seconds--thank you.
Cringe
John Murray my ADD KICKS in and it's all over
If there is one right answer.. aren't there "infinite - 1" answers?
stop. from the start you are missing a step. then you continue to calculate. first think of space and gravity as one. then imagine space and gravity in three or more dimensions. if it was thicker it could fit in a fish tank like a liquid. now shine the laser through that fish tank full of liquid stop. now drop a grain of sand into liquid stop now proceed to look at the laser going through the water. I don't know what you would call this f****** gravity space lensing. but if you move on from there then do your calculations for whatever else have fun
Isn't dark energy the fastest thing there is? As opposed to light?
Simple answer is we don't know...
We have very little info on dark matter and dark energy. Most if not all of it is just speculation. It's generally accepted that the speed of light is the "speed limit of the universe". Of course we could be wrong, but for now we say the speed of light is the fastest.
This is at least my understanding.
Well most theories say that dark (don’t get this confused with dark energy, they are different things) is faster than light but this is untrue since darkness is just the absence of light therefore darkness is just a concept. Scientists haven’t got much knowledge about dark energy or matter so it’s a possibility.
6 months to highschool if you don’t count summer break… don’t know how I understand some of he things she says at my age lmao
and I don't care if you figure out or not. because we haven't got that long lol
so u mean the smaller the core of the blackhole is the stronger it is...? (pls reply.. coz i quit engineering coz it has math in it... and engineering is not about how much u study but its abt how creative u r... engineering is a talent and not studies...
y not give the math to the mathmations..?! creats more employment)
Maybe because the role of engineers is to be able to create something that is physically and mathematically sound without having to go back and forth with mathematicians with concepts that have had no foresight as to whether they are feasible..
She has the same mouth as Brian cox
No need to watch if you are at a higher level then GCSE
Hello dummies..😙
pls give me ur email... i've got a theory
The first 5:30 offered nothing so with 14 mins left I am outta of here
@ColoredSpaces
She doesn't need to be funny or entertaining. She just needs to be informative. It detracts from what she's saying.
We failed to feed people on a planet with plenty of resources, food and presumably intelligent life. However, intelligent people are researching bullshit from space when they should be more into solving our own issues. If you think earth will collapse and we need to find an alternative planet to send people to, just like these Sci-Fi movies...I hope you have another guess coming because it is not going to happen.
And how do you know that something we could discover within the bounds of space wouldn't help cure all our current worldly problems? You don't, that's why we must continue regardless.
Understand your perspective. However, on the journey to get out into space and confirm the multitude of Theories, we create the tools and resources that not only serve the Space Mission, they provide a shared benefit to the people of Earth.
