The Physics of Black Holes - with Chris Impey

Black holes are the most extreme objects in the universe yet every galaxy has one at its centre.

Chris Impey explores the questions this profound discovery can help answer and the role black holes have played in theoretical physics.

Chris Impey is a University Distinguished Professor and deputy head of the astronomy department at the University of Arizona. His research has been supported by $18 million in grants from NASA and the National Science Foundation, and he has had 24 projects given time on astronomy's premier research facility, the Hubble Space Telescope.

This talk was filmed in the Ri on 9 May 2019.

I feel like I've watched enough videos about black holes by now, but somehow they keep pulling me in.

THIS is how you give a lecture. No lip smacking and “uuhh’s”. Well done, concise and understandable. Thankyou!

[alphacenturi]

You are a born lecturer. At last I have stumbled on someone I can listen to learn and understand astronomy.

"Research is what i do, when i don't know what to do"
I'm currently unemployed watching this at 5am!! love it!!!!

Chris Impey has a gift for conveying information. Granted there's no math here, but the concepts are dealt with in such a way as to make them completely accessible. What a fantastic lecture, and what a fantastic lecturer.

Like others have said, I hate when I start watching these RI talks late at night. I end up staying up most of the night. I enjoy them that much!

I love how he uses such rare words in almost a nonchalant manner, yet I have to go and google these words to see the intricately layered meaning behind them. Blasé, quiescent.. to name a few. This man is a treasure!

Good luck finding it now but Chris Impey's Essential Astronomy series of lectures is one of the modt fascinating things ive ever seen

[artoffugue]

This is easily the best lecture I've seen on black holes... and more. I think it's because it's easy to understand!

[seraphik]

fantastic lecture. also, that's the first time I've seen Hawking's grave. what an absolutely perfect, badass tribute - and such a flex, that you're so synonymous with black holes that you get to put one on your headstone.

[davidkennerly]

This guy is great! I learned several new things about black holes and I've been reading about them for decades.

[billyaustin]

A great lecture - one of those where almost every word went over my head, yet I was still absolutely captivated. Bravo Mr Impey 👏

[anwarsansari]

THE SMOOTHEST EXPLANATION, HE MADE ME UNDERSTAND AS IF I WAS STUDYING NEWTONS FIRST LAW OF MOTION.. CHRIS IS REALLY GREAT. HATS OFF

[siryoda]

This will be forever one of the most amazing videos on YouTube. The "holy crap" value is completely off the chart!

[StephensEFRC]

The best science talk I’ve seen in 50 years.

[sorcerykid]

Impressive lecture! I was just waiting for him to gloss over some key details, yet he literally covered every point from start to finish -- even touching upon nuances like the conservation of angular momentum while the star collapses and the dissipation of Hawking radiation for the black hole to evaporate and the paradox of information loss at the event horizon.

Thank you so much for uploading these Videos

[MrBitterman]

What an amazing lecture! Many thanks for the upload.

[MoriKitsune]

28:00 gave me goosebumps. Absolutely beautiful and humbling

[MarkLucasProductions]

That lecture was an exceedingly pleasant experience all round.
