The Spacetime Metric

Visual course · Season 1

Learn the physics before judging the claim.

From what a metric is to warp geometry, the quantum vacuum, and the experiments now under way.

Overlapping luminous wave modes fill an apparently empty space while two boundaries select which modes fit.
A conceptual field portrait—not a photograph and not a picture of literal particles.
