A mathematician at Purdue University claims to have come up with a proof for the Riemann hypothesis, often called the greatest unsolved math problem, though the work has yet to be peer-reviewed.
The hypothesis concerns the distribution of prime numbers. A prime number is divisible only by itself and one. Prime numbers are necessary for, among other tasks, encryption. Earlier this month, a group confirmed that it has found the largest prime number known about to date. The new number, expressed as 2 to the 24,036,583th power minus 1, has 7,235,733 decimal digits.
