“Lightning never strikes the same place twice”

The notion that lightning never strikes the same place twice is a deeply ingrained idiom, often used to suggest that an unusual or unfortunate event is unlikely to reoccur. This popular saying likely originated from a time before modern scientific understanding of electricity and atmospheric conditions, when lightning appeared to be a random and unpredictable force of nature, making a repeat strike seem incredibly improbable. It served more as a metaphor for rare occurrences than a statement of physical fact.

However, scientific evidence clearly demonstrates that this is a misconception. Lightning is an electrical discharge that seeks the path of least resistance between a cloud and the ground. Structures that are tall, isolated, or good conductors of electricity are prime targets, and once a path is established, it can be repeatedly used. For instance, the Empire State Building in New York City is struck by lightning approximately 20 to 25 times every year. The Eiffel Tower also experiences about ten strikes annually. Even a single lightning flash is often composed of multiple, rapid electrical discharges that hit the same spot in quick succession, too fast for the human eye to distinguish as separate events.

People continue to believe the myth partly due to its metaphorical convenience and the human tendency to perceive lightning as a singular, unpredictable event. The sheer speed and power of a lightning strike can make it seem like a "one-and-done" phenomenon, especially if it causes significant damage to an object, leading to the assumption that the location is no longer viable for another strike. Yet, modern lightning detection networks and extensive research, including studies by NASA, consistently confirm that lightning frequently revisits the same locations, making this old adage a fascinating example of how folklore can diverge from scientific reality.
