Final answer:
The Riemann Hypothesis is a conjecture in mathematics regarding the distribution of prime numbers and remains an unsolved problem.
Step-by-step explanation:
The Riemann Hypothesis is a conjecture about the distribution of prime numbers. It is one of the most famous and long-standing unsolved problems in mathematics, proposed by Bernhard Riemann in 1859. The hypothesis suggests that all non-trivial zeros of the Riemann zeta function have their real parts equal to 1/2. Proving or disproving this hypothesis has significant implications for number theory and the understanding of prime numbers. Despite numerous attempts by mathematicians, the Riemann Hypothesis remains unproved.
