Brian Greene on Artificial Intelligence, the Importance of Fundamental Physics, Alien Life, and the Possible Future of Our Civilization

March 14th was Albert Einstein’s birthday, and also PI day, so it was a fitting day to be interviewing well known theoretical physicist and string theorist Brian Greene – the author of a number of books including, The Elegant Universe, Icarus at the Edge of Time, The Fabric of the Cosmos, and The Hidden Reality!

About the Interview with Brian Greene

Brian Greene discusses implications Artificial Intelligence and news of DeepMind AI (AlphaGo) beating the world grand champion in the board game Go.  He then discusses physics string theory, the territory of opinion on grand unifying theories of physics, the importance of supporting fundamental science, the possibility of alien life, the possible future of our space-faring civilization and of course gravitational waves!

In answer to the question on the importance of supporting fundamental research in science, Brain Greene said:

I tell them to wake up! Wake up and recognize that fundamental science has radically changed the way they live their lives today. If any of these individuals have a cell phone, or a personal computer, or perhaps they themselves or loved ones has been saved by an MRI machine.. I mean any of these devices rely on integrated circuits, which they themselves rely on quantum physics – so IF those folks who were in charge in the 1920s had have said, ‘hey you guys working on quantum physics, that doesn’t seem to be relevant to anything in the world around as so were going to cut your funding – well those people would have short circuited on of the greatest revolutions that our species has gone through – the information age, the technological age – so the bottom line is we need to support fundamental research because we know historically that when you gain a deep understanding of how things work – we can often leverage that to then manipulate the world around us in spectacular ways! And that needs to be where our fundamental focus remains – in science!


Layered art of Brian Greene, background and series titleBrian Randolph Greene is an American theoretical physicist and string theorist. He has been a professor at Columbia University since 1996 and chairman of the World Science Festival since co-founding it in 2008. Greene has worked on mirror symmetry, relating two different Calabi–Yau manifolds (concretely, relating the conifold to one of its orbifolds). He also described the flop transition, a mild form of topology change, showing that topology in string theory can change at the conifold point.

Greene has become known to a wider audience through his books for the general public, The Elegant Universe, Icarus at the Edge of Time, The Fabric of the Cosmos, The Hidden Reality, and related PBS television specials. He also appeared on The Big Bang Theory episode “The Herb Garden Germination“, as well as the films Frequency and The Last Mimzy. He is currently a member of the Board of Sponsors of the Bulletin of the Atomic Scientists.

Can Spiritual Experience be Scientifically Validated?

At a Melbourne skeptic’s meeting in Australia, theoretical physicist Lawrence Krauss was asked whether spiritual experiences could ever be scientifically validated.

Lawrence Krauss – Can Spiritual Experience be Scientifically Validated _“The spiritual things — the exotic phenomena people experience — in general violate the things we know to be correct on the basis of experiment, so they’re highly likely to be wrong,” Krauss answered.

“I can’t say to someone who’s heard God in their ears that they’re not hearing God,” he continued. “But I can say that it’s much more likely that they’re hallucinating, based on what we know.”

As for the existence of extraterrestrial life, he said that accounts of alien encounters are “much more likely to be due to the irrationality of humans than the rationality of aliens.”

“When you think about the likelihood that a space-craft would come here,” Krauss said, “almost anything you can think about is more likely. And what science deals with is not ‘true’ and ‘false,’ it’s ‘likely’ and ‘less likely.’ And some things are so unlikely, you just chop them off.”

“So I can’t tell someone that what they’ve heard, or what they’ve seen, or [have had] some mystical experience — I can only say that it’s likely a coincidence,” he concluded.

“But none of us like to believe that things that happen to us are coincidences. We’re all hard-wired to believe that things that happen to us are significant.”

Lawrence KraussLawrence Maxwell Krauss (born May 27, 1954) is an American theoretical physicist and cosmologist who is Foundation Professor of the School of Earth and Space Exploration at Arizona State University and director of its Origins Project. He is known as an advocate of the public understanding of science, of public policy based on sound empirical data, of scientific skepticism and of science education and works to reduce the impact of superstition and religious dogma in pop culture. He is also the author of several bestselling books, including The Physics of Star Trek and A Universe from Nothing.

Initially, Krauss was skeptical of the Higgs mechanism. However, after the existence of the Higgs boson was confirmed by CERN, he has been researching the implications of the Higgs field on the nature of dark energy.

Krauss mostly works in theoretical physics and has published research on a great variety of topics within that field. His primary contribution is to cosmology as one of the first physicists to suggest that most of the mass and energy of the universe resides in empty space, an idea now widely known as “dark energy”. Furthermore, Krauss has formulated a model in which the universe could have potentially come from “nothing,” as outlined in his 2012 book A Universe from Nothing. He explains that certain arrangements of relativistic quantum fields might explain the existence of the universe as we know it while disclaiming that he “has no idea if the notion [of taking quantum mechanics for granted] can be usefully dispensed with”. As his model appears to agree with experimental observations of the universe (such as of its shape and energy density), it is referred to as a “plausible hypothesis”.
