Recently, we defined two scientific discoveries using Einsteinian science: the success/failure system and cosmic inertia. In this zenith of our work on Einsteinian science, we demonstrate through two analyses that Einsteinian science is a complete science to a theory of the universe, which can approach the true picture of the universe. First, we analyse archive materials to reveal scientific events we term Einstein’s paradoxes between Einsteinian science and unified field theory. Second, we analyse only two approaches to a theory of the universe: Einsteinian science and the unified theory approach. We demonstrate that Einsteinian science, philosophically and methodically, is a complete science, which contrasts with the Unified theory approach only practised in physics and mathematics and thus insufficient for a theory of the universe. Physicists face a potential turning point. Does Einsteinian science immediately arouse feelings and actions in physicists? Will Einstein’s paradoxes between Einsteinian science and unified field theory persist in physics forever? Science is still in its infancy in 2023, still as Einstein claimed in 1954!
