👉 In physics, a "kilo-hole" refers to an object that is so small as to be considered negligible compared to its surroundings. It is often used in the context of quantum mechanics and particle physics to describe particles with extremely small sizes, such as subatomic particles like electrons or quarks. A kilnhole is a mathematical concept introduced by Richard Feynman in his lectures on quantum field theory at the University of Chicago in 1965. It was named after an early example
