The declaration assigns the SI value of the speed of light as a real number. Analysts of the flyby anomaly cite it when converting thermal power asymmetry into thrust. The definition is a direct constant assignment with no derivation or computation steps.

claimThe speed of light is the constant $c = 299792458$ in meters per second.

background

The module analyzes the flyby anomaly as an Earth gravity-assist effect and concludes that thermal radiation asymmetry plus standard gravity modeling accounts for the observed velocity shifts. The speed of light appears as the denominator in the thrust relation $F = P_{asym}/c$, converting power into force for spacecraft of typical mass. Upstream imports supply gap functions $F(Z) = log(1 + Z/φ)/log(φ)$ and the master generator $F(z) = log(1 + z/φ)$, which fix the Recognition Science constants used in the broader mass and coupling ladders.

proof idea

Direct noncomputable definition that binds the literal integer 299792458 to the identifier c_speed.

why it matters in Recognition Science

The constant feeds the thermal_thrust definition, which is unfolded to establish thermal_acceleration_positive and the theorem that no beyond-standard-model physics is required. It therefore supports the module-level claim that thermal plus gravity updates suffice for the anomaly. The placement keeps all numerical constants explicit while the rest of the Recognition Science chain (T5 J-uniqueness through T8 D=3) remains in native phi units.
