In a chapter of his new book, John Lanier and I play with the idea that aliens are building virtual reality video games. The energy being consumed to motor that kind of virtual reality would take a huge amount of energy, right? This is like the attempts to detect a Dyson sphere around a star. That would be evidence of civilization instead of just looking for radio signals coming in. And so our game was to say, oh, it's being used. That's the power supply for the video games of the advanced realization. So it was a thought experiment. But the part of that of that chapter for example is to show that the whole point of developing strong theory is that sometimes you

In this important guide to science and society, cosmologist Stephon Alexander argues that physics must embrace the excluded, listen to the unheard, and be unafraid of being wrong. Drawing on his experience as a Black physicist, he makes a powerful case, in his latest book, for diversifying our scientific communities.

Shermer and Alexander discuss: his journey from Trinidad to the Bronx to professor of physics • what it’s like being Black in a mostly White and Asian field of science • systemic racism and misogyny • how to be an outsider inside a science • how to tell the difference between revolutionary and worthless new ideas • how do laypeople understand whether something is good science or not? • the double-slit experiment • superposition • connections between quantum physics and Eastern mysticism • creativity • What banged the Big Bang? • Are we living in a matrix? • Deepak Chopra’s mind monism • consciousness and the universe.

Stephon Alexander is a professor of theoretical physics at Brown University, an established jazz musician, and an immigrant from Trinidad who grew up in the Bronx. He is the 2020 president of the National Society of Black Physicists and a founding faculty Director of Brown University’s Presidential Scholars program, which boosts underrepresented students. In addition to his academic achievements, he was the scientific consultant to Ava DuVernay for the feature film A Wrinkle in Time. His work has been featured by the New York Times, the Wall Street Journal, WIRED, and many other outlets. He has been a guest on Nova, the Brian Lehrer Show, and Neil deGrasse Tyson’s StarTalk, among much else. The author of Fear of a Black Universe and The Jazz of Physics, Alexander lives in Providence, Rhode Island.
