Black Holes Shedding Information

In all honesty this is beyond my understanding but the cosmological implications are, to say the least, interesting.

Quote:
In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition. The work appears to resolve a paradox that Stephen Hawking first described five decades ago.

What it all means is being intensely debated in Zoom calls and webinars. The work is highly mathematical and has a Rube Goldberg quality to it, stringing together one calculational trick after another in a way that is hard to interpret. Wormholes, the holographic principle, emergent space-time, quantum entanglement, quantum computers: Nearly every concept in fundamental physics these days makes an appearance, making the subject both captivating and confounding.

Thanks for the video. I may just be a little bit closer to understanding.

Sabine Hossenfelder weighs in on this a couple of days ago. I don't understand so much of this I don't think I'm really competent to comment, but I think her take is that the paradox can't be resolved until we update either quantum theory or relativity. But it probably can't be solved at all.
