The Riemann Hypothesis: The Million-Dollar Mystery Behind Prime Numbers

The Riemann Hypothesis is one of the most famous unsolved problems in mathematics. It belongs to number theory, which is the study of whole numbers, especially prime numbers. Prime numbers are numbers such as 2, 3, 5, 7, and 11 that cannot be divided exactly by any smaller whole number except 1. They are often called the “building blocks” of arithmetic because every whole number can be made by multiplying prime numbers. The Riemann Hypothesis is connected to a special mathematical function called the Riemann zeta function. This function is linked to how prime numbers are spread across the number line. The mystery is about the “zeros” of this function, meaning the points where the function becomes equal to zero. The hypothesis says that all the important, or non-trivial, zeros lie on one special vertical line called the critical line. The Clay Mathematics Institute describes the hypothesis as saying that all “interesting solutions” of ζ(s) = 0 lie on a certain vertical straight line. This paper explains the Riemann Hypothesis in simple language for a high school student. It discusses prime numbers, the zeta function, zeros, the critical line, why the problem matters, and why it has remained unsolved for more than 160 years.
