PBT: Aether

PBT’s medium is a modern, dynamical relative of the historical aether — not a fixed, detectable rest frame (which Michelson-Morley ruled out), but a Lorentz-compatible field whose couplings are kept small enough to avoid the same fate. The Origins page covers where the idea started, back in the 2011-2016 posts that first used the term.

Covered in: Paper 2 (the dynamical aether field itself), Paper 5 (aether coupling to spin/entanglement), Paper 8 (full field-theoretic treatment), Paper 12 (summary equations).
