The Finite Universe Computational and Observational Proof That Infinity Is Physically Impossible

This paper presents convergent evidence from observational cosmology and computational quantum mechanics that the universe is finite, not infinite. The argument rests on two independent pillars: (1) Observational: Cosmologists assign percentages to cosmic composition (5% visible matter, 27% dark matter, 68% dark energy). Mathematically, you cannot calculate a percentage of infinity-5% of ∞ is indeterminate. Therefore, total energy must be finite. (2) Computational: We simulate quantum mechanics with finite information bounds (Bekenstein limit: 10¹²² bits). Results show: (a) Bell's inequality holds with finite information (entanglement requires no infinite precision); (b) Time is discrete recursion (Planck time steps, not continuous flow); (c) Wave function collapse is finite computation (1000 states, not infinite superposition); (d) Many-Worlds interpretation is finite (branching stops at 10¹²² bits, directly refuting infinite MWI). Combined, these results demonstrate that infinity is mathematically possible but physically impossible. The Big Bang had finite energy. The universe is computably finite. This is not philosophy, it is observational cosmology meeting computational proof.
