Interstellar Physics Paradigms and the Trap of Human Substantialist Thinking: What If a Civilization Began Directly with Time Field Theory

Taking a fictional "TFT civilization" as a mirror, this paper envisions what physics would look like for a civilization that, from the very dawn of its metrological awareness, grasps the core insight that all measurement is fundamentally periodic comparison. In their intellectual history, there is no Newtonian detour into substance ontology, no half-measure Einsteinian dualist revolution—only a natural line of reasoning from the stable benchmark of the perfect circle, to the self-consistency constraint of field distribution, and finally to the core equation of flux conservation. By contrasting how the two civilizations understand core concepts such as mass, gravity, the gravitational constant, and the equivalence principle, this paper reveals that all puzzles in human physics—dark matter, dark energy, singularities—are essentially path-dependent products of "substantialist intuition first, metric logic as an afterthought." Written with a tone both humorous and rigorous, this paper offers "alien handbook" annotations for the cornerstone concepts of human physics, and concludes that both civilizations observe the same universe. The difference never lies in the precision of telescopes or the depth of mathematics, but in the most fundamental divide: do you see the world as a collection of substances, or a field of relations?
