Einstein once said, “Imagination is more important than knowledge.” Some of his most brilliant scientific breakthroughs came out of thought experiments-- hypothetical scenarios taking place entirely in his mind. One of his most famous thought experiments illustrates the concept of the relativity of simultaneity, changing the way we understand space and time. Imagine a moving train with two bolts of lightning striking at either end. Would a passenger on the train see the lightning in the same way as an observer standing nearby?
