Riemann Hypothesis
The "Unsolvable" Problem
All non-trivial zeros of the Riemann zeta function have real part equal to 1/2.
Mathematicians have verified billions of zeros. All on the line Re(s) = 1/2. But they can't prove it must be so. They've been trying for 165 years.
Why 1/2 Is Necessary
The critical line Re(s) = 1/2 is the balance point between s+ and s- domains.
The zeta function encodes the distribution of primes โ the fundamental structure of number. Primes emerge from closure operations. Closure requires balance.
Zeros can ONLY occur where s+ and s- contributions cancel exactly. That's the definition of the critical line.
