Summary

Carlo Rovelli discusses loop quantum gravity, the nature of time, and how physics intersects with philosophy, challenging our understanding of reality and the universe’s fundamental structure.- 00:00 - IntroSPONSORS:- I personally subscribe to The Economist.

0:00.0	What happens if you fall into a black hole?
0:02.2	The results are very interesting.
0:03.8	The experimental results is a confirmation of something that the majority of loop quantum gravity community expected on theoretical reasons.
0:12.2	We see the black holes. We see the matter falling in, right?
0:14.8	We see the spiraling, the Christian disk, as they call it.
0:19.6	And we know, because we know generativity,
0:21.7	that matter, it's a spiling and then going into the horizon.
0:25.5	And we know generativity, so it goes into what we call the singularity.
0:31.1	What happened next to that matter?
0:36.3	Carlo Revelli, welcome back. It's been two years and I'm extremely happy to be speaking with you again.
0:42.8	Thank you very much, Kurt. It's a great pleasure being here with you again.
0:46.5	So as you know, there's some recent results, I believe from China that people present as a death blow to loop quantum gravity.
0:53.7	What are those results?
0:55.3	And do you agree with this assessment?
0:59.1	The results are very interesting.
1:01.8	They're experimental results.
1:05.0	They have not been presented a death blow to loop quantum gravity
1:08.9	by the authors of those results, not at all. And they are not a death blow to loop quantum gravity by the authors of those results, not at all.
1:12.5	And they are not a death blow to loop quantum gravity at all.
1:15.7	In fact, the opposite.
1:16.8	It's a confirmation of something that the majority of loop quantum gravity community expected
1:24.5	on theoretical reasons.
