Are we living in reality… or just really good code?

Are we living in reality… or just really good code?

In this episode of Robot Brains, Alex and Riley dive into the mind-bending world of simulation theory the idea that our universe could be a sophisticated computer program. From Nick Bostrom’s famous probability argument to quantum weirdness, pixelated space-time, and cosmic “glitches,” we explore the science, philosophy, and big implications of a simulated reality. Whether we’re in base reality or someone’s cosmic sandbox, one thing’s certain: the questions are fascinating. Stay curious… and watch out for Monday bugs. Disclaimer: Some of the concepts discussed in this episode (like quantum physics and simulation theory) are very complex, and I don’t fully understand every detail myself. I included them because they are fascinating ideas that many scientists and philosophers explore, and I hope listeners who know more, or want to learn, will find them interesting and thought-provoking.

Can Humans Really Live on Mars?

Mars has been called humanity’s next home. But is that realistic or just science fiction? In this episode of Robot Brains, Alex takes a deep, evidence-based look at what it would actually take for humans to live on Mars. From freezing temperatures and thin atmosphere to radiation risks, low gravity, food production, water extraction, and mental health challenges, we break down the real science behind surviving on the Red Planet. Could we build habitats underground? Can we create oxygen from carbon dioxide? Is Mars a backup planet or a technological experiment? This episode explores the limits of engineering, biology, and human resilience to answer one big question: Can people truly live on Mars? If you’re fascinated by space exploration, future technology, and the long-term future of humanity, this episode is for you.

What's inside a Robot's head?

Alex powers up Robot Brain to answer a BIG question: Do robots think like us? How do they think? Learn how robots see, learn, and make decisions. Play fun games and hear funny stories along the way. A brain-boosting adventure for curious kids! A podcast for kids by kids!!
