Read the full Quanta Magazine interview with Dr. Kara to learn more about her research: www.quantamagazine.org/to-see-black-holes-in-detail-she-uses-echoes-like-a-bat-20240212/

Its always nice when a researcher credits their grad students :)

It's always a good day when there's a new Quanta video

Always fun to learn new stuff regarding black holes.

Really love how you turned it into music in the end! Makes the topic understandable on so many levels.

An elegant approach to "imaging" accretion disks, elegantly told. Someone really needs to update the wikipedia NICER entry.

I'm currently watching an excellent NOVA PBS documentary on Black Holes. I'm at the part where they talk about the x-rays and jets and got really confused, so this was great to watch and helped me understand a lot more. Thanks, Dr. Kara & Quanta!

Want to see more from her. Great presentation.

Agreed, she is an excellent communicator

This is so cool!

What's the cello track in the beginning called?

Excellent video!

great science, great video, great presentation

When measuring time differences so close to a massive gravity field, how do you correct for time dilation? I guess the *exact* mass (aka the gravity forces) of the black hole is unknown and also the two measuring points probably have different gravity.

Great work. Looks like resolution is ~10 min or 0.8billion km. Sounds a lot, but accretion disk is itself of the order of ~1000 bn km!

hella sick!

Do you assume that the accretion disk is a uniform disk?

I like it even more how she tell the story

SAG Astar & the Milky way is a water fall, we are on the river's of time. While I think a black hole would be a Serene sink hole. The event Horizon. the very point where wheel meets track of a coal train on rail track's in a tunnel with the Waight of the World; I imagine the Sound heat & Waight of the very point between wheels & track. but then again. A continuous drip of water in the same tunnel can bend a metre of steel rail track. Crazy. Oh & that single drip. That sound & Echo. Is the same time it would take for two Black holes to collide. Only in a greater Waight heat & Radio wave's.

Trippy.

Awesome!!!🌟🌟💯💯

Nicer!

How did the largest black hole form❓ I mean how they can eat so much to grow❓ almost all galaxy’s center had a super massive black hole, but they can’t eat the entire galaxy ❗

Black hole sounded like the Doppler Effect to me

They are similar.

Maybe black holes are plasmoids?

I got distracted after they called the inner accretion disk "corona"😅

The title is misleading in my opinion.

I don't think that's the case at all. They are talking about observing X-Ray emissions, and how they made techniques and methods to model the energy output.

amazing voice and face you have... Not gonna lie, would not click on the video without the too-promising title but I expect more from the scientific community.

I wish people stopped saying "close to the speed of light". Please stop, people.

As I understand it, for relativistic effects these tonal changes are a pretty cool way to make them accessible to our senses on a more direct intuitional level. Ofc it's gimmicky
