Not as a metaphor, not loosely — the specific yellow of a wedding ring is a direct, measurable consequence of the same physics that governs black holes and keeps GPS satellites honest. Relativity has a reputation as the physics of the very fast and the very far away, cosmic and abstract, nothing to do with a Tuesday.
