    Is the Universe a Simulation? Andrew Pontzen
    Nov 17 2024
    Please join my mailing list here 👉 https://briankeating.com/list to win a meteorite 💥 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. Tune in to learn about the power and limitations of simulation!
