How Do Black Holes Die? | Edge Of Knowledge | Ars Technica

Astrophysicist Paul Sutter returns to once again take us to the Edge Of Knowledge, this time to ponder the paradoxes of black holes. If nothing is supposed to escape a black hole, how can they emit miniscule amounts of radiation? What's the fate of matter sucked into a black hole once the black hole itself dies? Dr Sutter is joined by fellow astrophysicist Dr. Moiya McTier to discuss what we know, what we don’t, and how we’re trying to find out more.

I'm super impressed by the confidence we (he) anncounces that black holes are super simple and gives me the impression that we know everything about the black holes.

Mr. Paul your students are really lucky to have you.👍

i'm not smart, and i don't know much of what he says... but i love learning from these videos.

I think information should have been explained better in the beginning of the video and then we could understand how it is lost. This remains unclear to be. Do you mean information in units of entropy (lb x)? Why do you expect processes to be invertible? 2+2 = 4 = 5 - 1. Same result but different calculation. Was information lost because from 4 we "don't know how to go back"?

Answering this question would have been more interesting than crushing an egg..

A paradox is something that can not be, it's a sign there was a mistake.

Aren't they just massive zip files?

All I can say is there is nothing boring about black holes.

Infinite Density was the name of my rock band

I really wish I had a friend who’s as fun to listen to about the thing they’re really nerdy with.

The potato and the plant go in the BH and their information vanishes from near infinity to zero, and it is compressed. What happens when you compress an infinite complexity or speed it up? Well in waves, it's like apond, if you speed up waves on a pond or you make a pond smaller, the waves become more compicated because they have more interaction, just like atoms in a star. So, BH's lose complexity on the outside and if you have imaginatio, they creat timespace on the inside.

Interesting topic, but the production is weird. Just say the thing, no need for weird on the side props.

She says there is a common misconception that a black hole sucks stuff in, then uses that expression to explain hawking radiation.

[jimstark]

My understanding is that black holes do not emit gamma rays. They are a results of interactions in the accretion disc. Hawking radiation is theoretical and has never been observed therefore the notion of a black hole evaporating is a theory. All observations indicate the opposite.

Sorry I don't buy 'the event horizon isn't special' argument. I don't think that any point which is going faster than the rest of the universe can be non special. I'm certain there's a sort of a shockwave (usually called a 'firewall') there that forms as the black hole does that contains all of the mass.

How do you feel about black holes having hair?

[octapc]

This video just doesn't gell with an over animated narrator.

[noanyobiseniss]

Black holes are the universes garbage collection routine.

[ReyArteb]

what happens to a black hole once it attracts to much material.(millions billions of years).. does it become a sun or a planet again?... could this be an engine that takes a billion years to cycle?
(kinda seems like natures way of cleaning up the mess of supernova)
my theroy is they are some type of drone/antennas absorbing and transmitting data to aliens....that or galactic parasites? ;)

That's something for male brains. I would be interested in viewer demographics for this video (how many females watch it).
