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
00:01:06 The true nature of time
00:24:57 The role of computational irreducibility in thermodynamics
00:30:07 The Ruliad and the nature of observers

Simulations today are powerful tools for exploring the mysteries of our universe, but how close can they come to replicating reality? Can we recreate everything through simulations, or are there limits we can’t overcome? And how do today’s powerful simulations shape our understanding of everything from galaxies to climate change?

Here today, to answer all of these questions and more, is none other than Andrew Pontzen. Andrew is a cosmologist and professor known for his expertise in using computer simulations to understand the universe. He’s the author of The Universe in a Box, where he unpacks the complexities of cosmic simulations and their surprising limitations. Pontzen’s work is at the cutting edge of how we model and predict phenomena ranging from galaxy formation to climate change, bridging theoretical physics with practical, big-picture questions about reality.

As we head toward an era where simulations and AI are central to scientific discovery, these questions are more important than ever.
