When the long-awaited day dawns and the aliens finally arrive on Earth, they might eat us and destroy the planet―or, just maybe, they might share the secrets of the Universe with us. When that time comes, will we be able to cross the communication barrier to beg for our lives? If the aliens do hold out those precious jewels of knowledge, will we even be able to grasp them? Professor Daniel Whiteson and Warner explode what we thought we knew about talking to our cosmic neighbors―and even science itself―by asking and answering questions both lighthearted and profound. Whiteson's book, Do Aliens Speak Physics?: And Other Questions about Science and the Nature of Reality, is available for purchase now.

Trace the intellectual and scientific history of each of his major contributions to the fields of science and philosophy, the challenges he faced, the criticisms he received, and his overarching reflections today. Additionally, discover how Penrose thinks about physics and hear his contrarian view of the foundations of quantum mechanics. Sir Roger Penrose is an English mathematician, mathematical physicist, philosopher of science, and Nobel Laureate in Physics. He is Emeritus Rouse Ball Professor of Mathematics at the University of Oxford, an emeritus fellow of Wadham College, Oxford, and an honorary fellow of St John's College, Cambridge, and University College London. Penrose has contributed significantly to the mathematical physics of general relativity and cosmology.

The truths of math seem to be unrelated to anything else—independent of human beings, independent of the universe. The sum of 2 + 3 = 5 cannot not be true; this means that 3 + 2 = 5 would be true even if there were never any human beings, even if there were never a universe! When then, deeply, is mathematics? Featuring interviews with Max Tegmark, Scott Aaronson, Mark Balaguer, Silvia Jonas, Gregory Benford, and Karen Uhlenbeck.

Physicist and computer scientist Stephen Wolfram explores how simple rules can generate complex realities, offering a bold new vision of fundamental physics and the structure of the universe. Additionally, from the foundations of cellular automata to the discovery of surprising patterns in nature, Wolfram shows how computation reshapes our understanding of reality and revolutionizes the way we think about science. Stephen Wolfram is a British-American computer scientist, physicist, and businessman. He is known for his work in computer algebra and theoretical physics. In 2012, he was named a fellow of the American Mathematical Society. He is the founder and CEO of the software company Wolfram Research, where he works as chief designer of Mathematica and the Wolfram Alpha answer engine.

Humanity’s future is now framed by artificial intelligence (AI) and increasing interventions in the body to enhance features and functions. This is transhumanism. Considering the stakes, and the dangers, a philosophical perspective is imperative. Featuring interviews with Paul Griffiths, Nathan Lents, Carol Cleland, Quayshawn Spencer, Rachell Powell, S. Joshua Swamidass, Terrence Deacon, and Massimo Pigliucci.

What is it about art that can elicit the sense of transcendence, going beyond the self, bursting the constraining bonds of semantic language? What is it about transcendence that it can be expressed by art? What in fact is transcendence, from a momentary escape from self to a full- blown mystical experience? How does the art-transcendence nexus engage the mind? We describe key terms and ideas. Featuring interviews with Simone Schnall, Julio Bermudez, Judith Wolfe, Oludamini Ogunnaike, Jonathan Berger, and Anjan Chatterjee.

We do explore what OBEs and NDEs would mean, if real, for theories of consciousness. This episode features interviews with Bernardo Kastrup, Etzel Cardeña, Àlex Gómez-Marín, and Liad Mudrik.

This podcast has nothing to do with good-faith truth-seeking and everything to do with performative bewilderment. It is to philosophy (in the Greek sense) what The History Channel is to the study of history.

Sounds like a bunch of people thoroughly confused about teleology and causality. They describe systems' functions as intended outcomes rather than as affordances en passant in evolution. Their dismissals of competing (more popular) theories sound flippant, not insightful. Maybe this is just what we should expect from a podcast that showcases mystifying conjectures rather than intriguing explanations.

That was spectacularly awful. I kept waiting for an intelligent statement, and then the episode ended.
