Bob & Mike's Big Idea: A New Law of Nature Sep 23, 2025

The universe loves making things complicated. From minerals and microbes to languages and societies, complexity keeps showing up — but why? Astrobiologist Mike Wong and mineralogist Bob Hazen think we’re missing a law of nature to explain this phenomenon. Hakeem sits down with them to understand – and kick the tires on – their bold new idea: what they call a Law of Increasing Functional Information. They break down how it works, why it matters, and how it could reshape our understanding of everything from life to language to the universe itself.

Guests Bios:

Robert Hazen is a mineralogist and astrobiologist at Carnegie Science and George Mason University. His pioneering research explores the origins of life and the evolving diversity of minerals on Earth. A prolific author and public communicator, Hazen has written widely on science, complexity, and the deep connections between the physical and biological worlds.

Mike Wong is an astrobiologist and planetary scientist at Carnegie Science whose work focuses on how life begins and evolves on worlds like our own. He is also a science communicator, hosting the podcast Strange New Worlds, where he brings complex cosmic ideas to broad audiences. Wong’s research and outreach bridge cutting-edge science with big-picture questions about life in the universe.

Robert Hazen and Michael Wong's new book Time's Second Arrow: Evolution, Order, and a New Law of Nature will be available in February 2026.

Black Hole Badass Sep 09, 2025

Black holes get a bad rap. They’ve been cast as the monsters of the cosmos — gobbling up stars and stretching anything that gets too close into cosmic spaghetti. But black hole expert Janna Levin thinks they’re just misunderstood. A theoretical physicist, author, and founding scientific director of Pioneer Works, Janna has spent her career decoding these mysterious objects. In this episode, she dives into the strange physics of black holes: what they are, what they sound like, what happens if you fall into one, and how there’s a lighter side to every black hole. Janna shares why black holes might not be the end of everything — but the beginning of something even weirder.

The Deepfake Detective Aug 26, 2025

In a world flooded with fake images, manipulated videos, and AI-generated voices, how do we know what’s real anymore? Hany has made it his mission to find out. A leading voice in AI research and digital forensics, Farid is a professor at UC Berkeley and Chief Science Officer at GetReal Labs, where he works to authenticate digital media and expose the fakes. In this episode, Hakeem and Hany dive into how we got here. How does AI really work? How are deepfakes detected? And what does the future hold for truth in the digital age? Plus, Hakeem puts Hany to the test: can he tell the difference between real and AI-generated headlines? And can Hakeem tell a deepfake version of Hany from the real thing?

Mind of a Fossil Hunter Aug 26, 2025

What do fossilized leaves, an asteroid, and Florida sinkholes have in common? Dr. Kirk Johnson is Sant Director at the Smithsonian Institution, National Museum of Natural History, and has the answers. Kirk oversees one of the largest natural history collections on the planet – and he’s spent his career digging into the story of life on Earth across millions (and billions) of years. In this episode, Hakeem and Kirk explore the science of “deep time,” how fossils actually form, and the surprising origins of Earth’s oceans. Plus, Kirk shares some hot tips on fossil hunting and how to count the number of leaves on a tree … because you never know when you might need these skills.
