Comparative Framework: Classical Mechanics → Relativity → Extended Classical Mechanics (ECM)

Conceptual and Equation-Level Comparison
Aspect Classical Mechanics (Newtonian) Relativity (Einstein) Extended Classical Mechanics (ECM)
Ontology Absolute space and time; point masses 4-D manifold governed by energy–momentum tensor Same 4-D manifold, but introduces a signed debit term −Mᵃᵖᵖ to track displaced energy within the mass–field system
Mass Symbol m = constant scalar m = invariant rest-scalar Mᵉᶠᶠ = Mᴍ − Mᵃᵖᵖ — dynamic, field- and frequency-dependent effective mass
Gravitational Source ρₘ (matter density only) T₀₀ = ρₘ c² (matter term only) T₀₀ = (Mᴍ − Mᵃᵖᵖ)c² = Mᵉᶠᶠ c² — instantaneous field–frequency balance
Equation Novelty F = m a ; ∇²Φ = 4πGρₘ Field equation Gμν = 8πG Tμν All classical and relativistic forms recast via ρ → ρₑ𝒻𝒻 = (ρₘ − ρₐₚₚ)
Dynamical Law F = m a (static) Geodesic motion in curved spacetime Fᴇᴄᴍ = Mᵉᶠᶠ aᵉᶠᶠ — a mutually adaptive triplet (F, Mᵉᶠᶠ, aᵉᶠᶠ)
New Free Constant? G (introduced by Newton) None (c and G known) None (h, c, G retained)
Role of G Couples constant masses Couples invariant rest-masses Couples dynamic effective mass balance (Mᵉᶠᶠ ↔ field)
Role of −Mᵃᵖᵖ Universal negative gravitational charge; records energy displaced from the real-mass field, dynamically reducing or inverting Mᵉᶠᶠ to represent field-mediated loss or reversal of gravitational influence
Unique Physical Effect Local g < 0 inside bound systems when Mᵃᵖᵖ > Mᴍ
Legacy Limit v ≪ c, Φ ≪ c² → Newtonian domain Mᵃᵖᵖ ≪ Mᴍ → reduces to Newton + Einstein limits
Conceptual Leap Force causes acceleration Geometry causes acceleration Mass-energy bookkeeping causes acceleration change
Anomaly Addressed Terrestrial orbits Mercury perihelion shift, light bending Coma repulsion, flat rotation curves, lab weight dip without Λ
Novelty Verdict New physics (introduces G) Re-interpretation (no new constant) New physics variable −Mᵃᵖᵖ — energy coins pre-exist, debit column formalized
