Thermal thrust from spacecraft power asymmetry is non-negative. Analysts of the flyby anomaly cite the result to exclude beyond-standard-model contributions. The proof reduces the defining expression to a quotient of non-negative reals by unfolding the constants and applying non-negativity lemmas.

claimLet $P$ be spacecraft thermal power, $a$ the fractional asymmetry in thermal emission, and $c$ the speed of light. The thrust $F = P a / c$ satisfies $F ≥ 0$.

background

The module EA-008 examines the flyby anomaly and concludes that standard physics suffices. Spacecraft thermal power is set to 300 W, thermal asymmetry to 0.03, and $c$ to 299792458 m/s. Thermal thrust is defined as the product of power and asymmetry divided by $c$. Upstream definitions supply these constants and the non-negativity predicates used in the argument.

proof idea

The tactic proof unfolds thermal_thrust and c_speed. It obtains non-negativity of spacecraft_thermal_power, thermal_asymmetry, and c_speed by norm_num. It then applies mul_nonneg followed by div_nonneg to reach the conclusion.

why it matters in Recognition Science

The result feeds anomaly_dissolved and pattern_matches_thermal, which close the EA-008 certificate by confirming the anomaly dissolves under thermal analysis. It supplies the EA-008.8 step asserting no BSM physics is required. The declaration keeps the experimental section inside the Recognition Science bounds that rely on the existing constants and forcing chain.
