Are Virtual Particles A New Layer of Reality?
Summary
This episode investigates the true nature of virtual particles, arguing they are mathematical artifacts of perturbation theory rather than physical entities popping in and out of existence. The host explains how these tools approximate quantum field interactions and clarifies misconceptions about vacuum fluctuations, Hawking radiation, and the Casimir effect.
