The "All At Once" Universe Shatters Our View of Time

The "All At Once" Universe Shatters Our View of Time

Theories of Everything with Curt Jaimungal · 2025-04-11

Today we are joined by physicist and philosopher Emily Adlam for her first appearance on Theories of Everything to challenge one of the deepest assumptions in science: that time flows. In this thought-provoking conversation, Adlam presents her “all-at-once” view of physics, where the universe is more like a completed Sudoku puzzle than a film playing forward. We explore the measurement problem in quantum mechanics, the role of the observer, the illusion of causality, and why these foundational questions demand both philosophical clarity and scientific precision.

Theories of Everything with Curt Jaimungal

Exploring theoretical physics, consciousness, Ai, and God in a technically rigorous manner. If you'd like to support this endeavor, then please visit the Patreon ( https://patreon.com/curtjaimungal ). Thank you for your charitable and kindhearted support. My name's Curt Jaimungal, a Torontonian with a degree in mathematical physics from the University of Toronto and I analyze various Theories of Everything from this analytic perspective, though more and more opening up to alternative approaches. The separating factor of TOE from other podcasts is its focus on depth even at the risk of limiting the audience due to how much detail we delve into subjects. Paralleling the intensity found in academic discourse, we're increasingly embracing a spectrum of unconventional ideas to conduct research during this podcast, rather than merely conveying existing information.
