Summary

Lawrence Krauss is an internationally known theoretical physicist and bestselling author, as well as being an acclaimed lecturer. He is currently President of The Origins Project Foundation, and host of The Origins Podcast, His wide research interests have focused on the interface between elementary particle physics and cosmology, including the origin and evolution of the Universe and the fundamental structure of matter. Among his numerous important scientific contributions was the proposal, in 1995, that most of the energy of the Universe resided in empty space. Krauss previously served as Director of Arizona State University's Origins Project, and Foundation Professor for a decade from 2008-2018, and also as Chair of the Board of Sponsors of the Bulletin of the Atomic Scientists from 2006-2018. Prof. Krauss has held endowed professorships and distinguished research appointments at institutions including Harvard University, Yale University, University of Chicago, Boston University, University of Zurich, University of California at Santa Barbara, Lawrence Berkeley Laboratory, the European Center for Nuclear Research (CERN), Case Western Reserve University, Australian National University, Arizona State University, and New College of Humanities. In 2008 he created and served for a decade as Inaugural Director of the Origins Project, a national center for research and outreach on origins issues. He has written over 500 publications and 10 popular books, including the international best-sellers, The Physics of Star Trek and A Universe from Nothing. Among his numerous awards are included the three major awards from all 3 US physics societies and the 2012 Public Service Award from the National Science Board for his contributions to the public understanding of science.

0:00.0	Welcome to Part 2 of this special two-part episode of The Impossible, featuring Brian Keating's fascinating in-depth discussion with physicist and prolific author, Lawrence Kraus. Any sufficiently advanced technology is indistinguishable from magic. from magic.
0:34.0	I wanted to just read to you a statement that I got from Comron Vafa when he was on the show.
0:40.0	I asked him, I said, Comron, you know, one of the Knox against strength theory is that it
0:44.4	it doesn't have you know it doesn't make predictions that are testable and
0:48.7	therefore cannot be can not be falsified and then he went into the black hole entropy that it can be
0:55.2	reproduced to show the degrees of freedom that back in Stein and
0:59.1	in a two-dimensional black hole yeah in a two-dimensional black hole which we don't live in by the way.
1:04.0	Exactly right.
1:05.0	So I mentioned that.
1:06.0	And then he said, okay, so I said, come on, come on,
1:08.0	then he said, so for example, if you take an electron,
1:11.0	it has a mass, and if you compute the mass of the electron in the
1:13.9	fundamental units of physics which is plank mass it's a very tiny mass and
1:17.8	plank mass something on the order of 10 to the minus 23 it's a very tiny
1:20.8	number so you say great do we have any prediction that the electron mass should have been this small without knowing that there is an electron. Just by knowing that there is electric charge. And by knowing that there is dark energy in the universe, you find a bound on the electron mass from string
1:33.7	theory you found that it's bounded from on the upper end by 10 to the minus one and
1:38.1	above 10 to the minus 31 on the lower end okay so Lawrence what Lawrence, what do you make of that? What would you give
1:45.3	come run if he takes your, takes a cl- He's basically saying the electron mass is
1:49.6	prediction. It could have been 10 to the minus 32 of the of the plank mass, but it's not it's between 10 minus 31 and 10 the minus 1
1:58.1	A big range, but it's a prediction. It could be wrong to be falsified I don't think it's well look it I don't think it's worth getting hung up because the theory is just so premature
2:07.2	That I'm not worried about its predictions because I don't think I mean what he's giving is just a dimensional analysis argument which is fine is basically if you have a if you have the string
2:16.8	coupling constant of the plank mass ultimately if you combine things you're going to get some numbers.
