The Universe Didn’t Come From Nothing | The Peter McCormack Show

28 Aug 2026 · 1 h 46 min

I joined Peter McCormack to dig into one of the deepest unanswered questions in physics: what is time, and why does it only seem to move in one direction? My answer might surprise you. Time may not be a fundamental feature of reality at all, and understanding space, matter, and energy still doesn't mean we understand the universe itself.

We cover:

- What may have existed before the Big Bang

- Why something can't truly come from nothing

- How my work with the Simons Observatory could detect gravitational waves from the universe's earliest moments

- What dark matter actually means

- Why even a film as detail-obsessed as Interstellar still gets the physics wrong.

The conversation then turns from cosmic time to human time: mortality, family, meaning, and attention. We get into UFO disclosure, the collapse of institutional trust, and whether AI can ever reproduce the embodied human insight that let Einstein transform physics. My take: AI remains a tool built to serve humanity, and it's time we stop apologizing for humanity's greatness.
