In 2017, a chemist Salvatore Torquato discovered that prime numbers, when modeled as physical particles, produce a unique, crystal-like diffraction pattern that reveals an "effectively limit-periodic" structure. By bouncing simulated light off a long sequence of around a million primes starting from 10000000019, they uncovered a hidden, fractal-like pattern in primes, in what seemed to be random numbers.
