    Is reality fundamentally mathematical? Is our universe just one of many? And will we ever discover extraterrestrial life? 

    This week on Into the Impossible, I sit down with renowned physicist and machine learning expert Max Tegmark to discuss some of the most fundamental questions of our time! Tegmark has dedicated his career to uncovering the mathematical fabric of reality, proposing that our universe itself might be a vast mathematical structure and that we could be living in a multiverse of endless possibilities. His work goes beyond physics to tackle the transformative power and ethical challenges of artificial intelligence, an area where he believes humanity must tread carefully.

    In the first part of this mind-bending interview, we discuss his mathematical universe hypothesis, the search for extraterrestrial life, and AI’s role in science. Tune in!

    Key Takeaways: 


    00:00 Intro

    00:49 The multiverse and mathematical structures 

    02:33 Theory of inflation and the multiverse

    06:52 Levels of multiverses and mathematical structures

  • In 2022, I had the honor of delivering the commencement address at Brown University.
    I used this incredible opportunity to talk about a personal hero of mine: Galileo Galilei. Galileo was a scientist like no other. He boldly challenged the status quo through his discoveries and relentlessly pursued the truth, even when persecuted for doing so. His journey offers timeless lessons for scientists today, especially for graduate students who will shape the future of science.
    My goal with this lecture was to inspire the next generation of thinkers, and I hope it does the same for you.

  • What is the cosmic microwave background (CMB), and why is it essential in cosmology? What role do instruments like BICEP and the Simons Observatory play in studying the early universe? And is the multiverse real? 
    I had the absolute pleasure of discussing these questions with Dr. Hugh Ross, astrophysicist and founder of Reasons to Believe. 
    In our conversation, Hugh and I discuss my research on polarization signals in the cosmic microwave background (CMB), focusing on my work with the BICEP, POLARBEAR2, and Simons Array telescopes. These signals are key to understanding the inflationary event that shaped the early universe. We explore how ongoing data collection helps us learn more about the universe’s origins. I also share a brief overview of my spiritual journey, from a Catholic upbringing to atheism and now being a practicing Jew with agnostic beliefs.

  • A few weeks ago, I released a video about whether string theory’s biggest competitor, Loop Quantum Gravity, might have suffered a fatal blow.
    The video sparked a lively debate across YouTube, with creators like Sabine Hossenfelder and Phil Halpern making reaction videos and Carlo Rovelli even reaching out to me personally, asking me to take it down.

  • Is string theory actually science?
    Many argue that string theory cannot be proven and should therefore be abandoned. For them, string theory is not science at all. But are they right?
    I had the pleasure of discussing this with none other than Cumrun Vafa! Cumrun is a Professor of Mathematics and Natural Philosophy in the Department of Physics at Harvard University, where he has been researching and teaching theoretical physics since 1985. His primary area of research is string theory. 
    In our interview, we discussed whether we should trust string theory, fine-tuning, and the message he'd put into a billion-year time capsule. We also talked about his book Puzzles to Unravel the Universe.

  • Have we been completely wrong about the Higgs boson? What if it’s not what we think but something far more elusive? And what does the origin of mass in the universe have to do with music?
    Here today to explore these mind-bending questions is theoretical physicist Matt Strassler. Matt is known for his work in particle physics, particularly in the context of the Large Hadron Collider (LHC) and quantum field theory. He has been involved in research on the Higgs boson, supersymmetry, and other topics in high-energy physics. 
    In our insightful interview, we dive into the mysteries of quantum physics, the nature of space, and how waves—not just particles—form the building blocks of reality. 
    Tune in to find out how the Higgs field gives mass to everything in the universe!

  • Is the universe hiding extra dimensions we can’t see? Could a graviton – a particle we haven’t even proven to exist – change everything we know about the cosmos? And what does the future of physics hold if the standard model fails?
    Today, I sit down with the renowned cosmologist Dan Hooper to discuss some of the most complex and exciting theories in modern cosmology. Dan is a leading theoretical physicist at Fermilab and a professor at the University of Chicago, specializing in the mysteries of dark matter, the early universe, and extra dimensions. 
    In this thrilling episode, Dan and I explore how hidden dimensions and mysterious particles could fundamentally challenge our understanding of the universe!

  • What if everything you know is just a simulation? 
    In 2022, I was joined by the one and only Nick Bostrom to discuss the simulation hypothesis and the prospects of superintelligence.
