The theory of relativity. Have tried many times to understand time dilation in a layman's terms rather than the maths. In other words, why does going extremely fast mean that time actually slows down for you relative to someone who is slower or stationary? Over the years I've tried to grasp this but it's always just eluded me as a phenomenon which can be explained in practical terms. If there are any physicists on here who know of a really clear explanation of how speed (and gravity) could mean that you could be younger than your own children etc.
