ABSTRACT: The object formally designated C/2025 N1 (ATLAS) has been widely discussed as a candidate third interstellar object (“3I/ATLAS”) due to its strongly hyperbolic trajectory. In standard celestial mechanics, an interstellar origin is inferred when the original barycentric eccentricity significantly exceeds unity prior to planetary perturbations. This interpretation, however, implicitly assumes that cometary dynamics are governed solely by gravitational forces and conventional outgassing. In this work, we propose an alternative hypothesis: C/2025 N1 (ATLAS) is not interstellar but a Small Solar System Body (SB) originating from the Oort Cloud, consistent with the framework of World-Universe Cosmology (WUC). We argue that its large excess velocity can be explained by a non-gravitational internal acceleration mechanism involving partial conversion of the rotational energy of the nucleus into the translational kinetic energy of the SB. Within WUC, the Universe is structured as a hierarchy of interaction regimes—Macro-world (gravity), Large-world (extremely-weak interaction), Small-world (super-weak interaction), and Micro-world (weak interaction). Previous studies associate Ball Lightning [1] with SB1 and interpret the Tunguska superbolide [2] as an SB2 analogue. Extending this hierarchy, we identify C/2025 N1 (ATLAS) as an SB3 object. This model naturally accounts for its extreme hyperbolic excess velocity without invoking an interstellar origin and leads to specific, testable predictions regarding kinematics, activity, and radiation signatures. We compare these predictions with observations of ʻOumuamua, C/2019 Q4 (Borisov), and a growing population of low-albedo asteroids and “dark comets” exhibiting dust-poor outgassing.
