Welcome to Quantum 101, where the rules of time and space are about to get a whole lot more interesting.
Relativity is a fancy way of saying that time and space are not as rigid as you thought they were. It's like the ultimate party trick: "I'm not late, I'm just in a different time zone!"
But seriously, relativity is a fundamental concept in physics that explains how gravity and motion affect the passage of time and space. It's like a cosmic game of "catch me if you can" with time and space.
