Text: This bold guess about the solutions to a certain complex-valued infinite series (made by the incomparable Bernhard Riemann in 1859) would, if true, have far-reaching implications for the structure of the most basic of entities, the natural numbers.
Entailment: Should this guess about how some infinite series might be solved prove true, there could be big implications about the natural numbers.
Contradiction: This careless guess, which has never been made before, is flawed and is rather meaningless.
