How should we communicate big ideas? How do science and poetry differ in their communication of knowledge? And can poetry enhance our understanding of cosmology?
Today, I’m joined by the renowned theoretical physicist and author of the thought-provoking book “Origins,” Joseph Conlon. In his book, Joseph reveals the origins of our universe through two long-form poems. With his extensive expertise in cosmology and philosophical thought, he sheds light on how the language of science not only explains the cosmos but also inspires us to reflect on the deeper meanings behind the laws that govern it. We also dive deep into string theory, string theory alternatives, and the current state of physics.
Tune in to learn more about the intersection of poetry and science!

What is time? Is it just a ticking clock, or is it something more profound?
In this thought-provoking episode of Into the Impossible, Stephen Wolfram challenges everything we know about time, offering a revolutionary computational perspective that could forever change how we understand the universe.
Stephen Wolfram is a computer scientist, physicist, and businessman. He is the founder and CEO of Wolfram Research and the creator of Mathematica, Wolfram Alpha, and Wolfram Language. Over the course of 4 decades, he has pioneered the development & application of computational thinking. He has been responsible for many discoveries, inventions & innovations in science, technology, and business.
He argues that time is the inevitable progress of computation in the universe, where simple rules can lead to complex behaviors. This concept, termed computational irreducibility, implies that time has a rigid structure and that our perception of it is limited by our computational capabilities. Wolfram also explores the relationship between time, space, and gravity, suggesting that dark matter might be a feature of the structure of space.
Tune in to discover the true nature of time.
Key Takeaways:
00:00:00 Intro

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.
Now, I want to clarify the situation and share my perspective on whether Loop Quantum Gravity is truly on its last legs—or if there’s more to the story.
Tune in to the Loop Quantum Gravity War!
Key Takeaways:
00:00 Intro
01:02 My initial video on loop quantum gravity
03:42 Quick recap of my correspondence with Carlo Rovelli
04:32 The problem with string theory and loop quantum gravity

Discrepancies between different measurements of the Hubble constant have caused a major crisis in cosmology.
Our guest today, the incredible Wendy Freedman, is at the forefront of efforts to resolve this tension. Known for her pioneering work on the Hubble Key Project and her important contributions to the measurement of the Hubble constant, Wendy is now using the James Webb Space Telescope to bring clarity to this debate.
With decades of experience and a deep understanding of the complexity of cosmic measurements, there is no one better to shed light on this issue.
So, can the James Webb Space Telescope help solve one of the biggest puzzles in cosmology?
Tune in to this episode of Into the Impossible to find out!—
Key Takeaways:
00:00 Intro
01:18 The role of JWST in solving the Hubble tension
04:01 Comparing different distance indicators

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!
