Today, the standard physical model of cosmology faces a structural deficiency when explaining the earliest moments of the universe's genesis. The traditional "Big Bang theory" assumes that the universe emerged from a "singularity"—a point whose volume approaches zero and whose density and gravity approach infinity. This paper proposes an alternative conceptual framework based on "fluid thermodynamics" and "topological analysis of geometric dimensions". It explains the genesis of the universe and its exponential acceleration as a mechanical system governed by pressure differentials and the square-cube law, eliminating the need for the mathematical singularity hypothesis.
