People who allegedly are in contact with good, communicative Aliens, just need to ask the 'space brothers" for the solution of the Riemann Equation.
The Riemann zeta-function ζ(s) is defined for all complex numbers s ≠ 1. It has zeros at the negative even integers (i.e. at s = −2, s = −4, s = −6, ...). These are called the trivial zeros. The Riemann hypothesis is concerned with the non-trivial zeros, and states that:
The real part of any non-trivial zero of the Riemann zeta function is ½.
Thus the non-trivial zeros should lie on the so-called critical line, ½ + it, where t is a real number and i is the imaginary unit.
A $1,000,000 prize has been offered by the Clay Mathematical Institute for the first correct proof.
