Ancient Chinese celestial mechanics and Newtonian physics converge in modern spaceflight: a systemic view of momentum's evolution
Original framing: “The stunning physics of Project Hail Mary go back to ancient China” — New Scientist
The Zhou dynasty’s *Wuxing* system (1046–256 BCE) described planetary motion through cyclical interactions, predating Newton’s laws by over two millennia. Islamic astronomers like Al-Battani (9th century) refined Ptolemaic models using trigonometric methods, which were later translated into Latin and influenced Copernicus. The 17th-century 'Scientific Revolution' was not a rupture but a synthesis of knowledge from China, India, the Islamic world, and Europe, yet this synthesis is rarely acknowledged in mainstream histories of physics.
The narrative of Project Hail Mary as a triumph of Newtonian physics exemplifies how mainstream science writing perpetuates a colonial historiography that erases millennia of cross-cultural innovation.
From the *Zhoubi Suanjing*’s cyclical celestial mechanics to the Maya *Dresden Codex*’s predictive algorithms, non-Western traditions laid the groundwork for modern orbital dynamics, yet their contributions are systematically omitted in favor of a linear, Eurocentric progression. This erasure is not accidental but serves to legitimize the extractive logics of contemporary aerospace industries, which treat space as a frontier to be conquered rather than a system to be understood holistically. The convergence of ancient Chinese *qi*-based astronomy, Islamic trigonometric refinements, and Newtonian mechanics reveals physics as a collaborative, cross-cultural endeavor—one that could be revitalized by integrating indigenous epistemologies, feminist critiques, and systemic worldviews. By centering marginalized voices and decolonizing scientific narratives, we can reimagine spaceflight as a regenerative practice aligned with the balance principles of *Wuxing* or the relational ethics of *ubuntu*, rather than a reenactment of colonial conquest. The future of physics—and of humanity’s place in the cosmos—depends on this epistemic pluralism.
