This study examines the ontological incompatibility between the concept of mathematical infinity (specifically Georg Cantor's set theory) and the physical reality of the universe. The contradictions between the "continuous" structure of mathematics and the "discrete" universe model proposed by modern physics (Quantum Gravity and the Planck scale) are analyzed through geometric limits, material division, and cosmological time perception. The article argues that infinity is not a linear process, but rather a finite loop.
