PART 5: RELATIVITY — THE DEATH OF THE BACKGROUND

Ch. 5.1: The Michelson-Morley Null Result (The experimental crisis)
Ch. 5.2: Lorentz's Mathematical Fictions (Length contraction, Local time, Transformations)
Ch. 5.3: Poincaré's Group Theory (The Relativity Principle as universal law)
PHIL Embedded (The Erasure Restored): Lorentz and Poincaré had the math. The debate is Instrumentalism vs. Operationalism.
Ch. 5.4: Einstein's Operational Epiphany (Defining time by light clocks, Relativity of Simultaneity)
Ch. 5.5: Relativistic Kinematics & Dynamics (Time dilation, E=mc²)
Ch. 5.6: Minkowski Spacetime (The block universe. The abolition of absolute time)
PHIL Embedded: The final epistemological lesson: Newton's absolute time was never a fact; it was a metaphysical assumption that failed operational definition.
