Quantum mechanics predicts the behavior of microscopic systems, but it’s counterintuitive. The double-slit experiment is one of the most counterintuitive experiments in science. Quantum mechanics explains the double-slit experiment as well as others. The quantum theory is based on a theory of quantum mechanics based on a theory of relativity.
Quantum mechanics says all objects have both wave and particle properties. Light, which throughout the 19th century was known to be a wave, was also found to have wave properties by the 1920s, was also found to have particle properties. And electrons were previously known as particles if they behaved as waves or particles. This results in an interference pattern, demonstrating the wave nature of light.
