Spacetime Metric Engineering

A 13-lecture series on warp metrics, the quantum vacuum, and what experimenters can actually try.

Lecture 7 · Block C — The quantum vacuum + zero-point energy · 40 min · HOST

QFT and the vacuum

Quantum field theory in 30 minutes: the vacuum is not empty.

About this lecture

Mode expansion, the harmonic oscillator zero-point, vacuum expectation values. Why the vacuum is not empty. Closes with an experimenter corner on vacuum thermal-noise-floor characterization with a precision balance (~$3–8K).

What you'll learn

Each claim in this lecture is placed on the four-tier disciplinary spine: peer-reviewed-replicated, peer-reviewed-once, patent-attested, or claim-only. By the end of Season 1 listeners can read any new physics claim in this territory and place it correctly.
