Summary

Juan Maldacena joined Professor Brian Keating for his first-ever podcast to discuss his fascinating work on black holes, AdS CFT, and 'human traversable wormholes and fundamental physics. We discussed the Multiverse, Black Holes, Wormholes, SETI, Life on Einstein Lane at the Institute for Advanced Study, wormholes in movies like Interstellar, and more. Brian and Juan start by chatting about his recent paper "HUMANLY TRAVERSABLE WORMHOLES" https://arxiv.org/abs/2008.06618 which is based, in part, on this earlier paper: "Traversable wormholes in four dimensions" https://arxiv.org/abs/1807.04726 Sign up for Professor Keating's newsletter, we'll send you links to download two explanatory talks on these papers. Please join my mailing list; just click here 👉 http://briankeating.com/mailing_list.php We also discussed an interesting economic analog to the Higgs Mechanism first elaborated by Dr. Pia Malaney and Dr. Eric Weinstein, explaining gauge theory and electromagnetism. See Juan's paper "The symmetry and simplicity of the laws of physics and the Higgs boson" here: https://arxiv.org/pdf/1410.6753.pdf . You will also enjoy his video lecture based on that paper here: https://www.youtube.com/watch?v=OQF7kkWjVWM Juan Martín Maldacena (September 10, 1968 in Buenos Aires, Argentina) is a theoretical physicist and the Carl P. Feinberg Professor in the School of Natural Sciences at the Institute for Advanced Study. He has made significant contributions to the foundations of string theory and quantum gravity. His most famous discovery is the AdS/CFT correspondence, a realization of the holographic principle in string theory.

0:00.0	It's often said that when we fall into a black hole, we die at the singularity because the title
0:12.4	forces or the forces of gravity will kill us.
0:14.0	If we fall into stellar mass black hole for example,
0:17.0	so a black hole with the mass of the sun which has a size of further a few kilometers.
0:20.0	So if we fall into such a black hole, we are still bigger than the size of the
0:24.4	black hole, but we will be killed before we get even to the horizon. You need some black hole
0:28.8	of further the size of the earth, so the horizon should be of order the size of the Earth in order for us to fall and not die at least at the horizon
0:37.5	And for similar reasons in this this one call has to have neck or an opening or connecting the two points in space time, which has the size of the earth.
0:46.8	And under those circumstances you could fall in and not be killed by the tidal forces.
0:59.0	Welcome to your listeners to this higher dimensional episode of Into the Impossible. From the Legendary Institute for Advanced Studies in Princeton, New Jersey,
1:02.2	the former academic home of Einstein and Oppenheimer.
1:05.5	We bring you, Theoretical physicist Juan Maldacina, taking us over the event horizon into the
1:10.6	mysteries of black holes, into the even stranger world of wormholes.
1:15.0	Could it be possible for an object the size of well let's say a human being to punch
1:19.9	through space and time with just the right-sized black hole?
1:23.9	And what can the theoretical study of wormholes reveal about the nature of
1:27.5	quantum gravity and inflationary cosmology?
1:31.1	Was our favorite cinematic physics director Christopher Nolan on the right track with
1:34.6	Interstellar?
1:36.6	Professor Maldacenus' theoretical perspectives may expand the dimensions of your mind even more.
1:42.3	If you love Black Hole physics and exploring the nature of the
1:44.6	universe, keep into the impossible in your feeds by subscribing and following. Pull in
