“Lightning never strikes twice in the same place,” it’s a way of saying that if something very unlikely, whether it’s good or bad, it’s already happened, it probably won’t happen again.
But does this famous popular phrase have scientific evidence?
For a matter of probability, one would tend to think that if lightning falls on a certain site, this will not happen again for a long time or never. However, it is quite the opposite: the rays may fall and will fall in the same place during the same storm or at another time.
Lightning is a natural electrical discharge of high-power static electricity, which occurs during thunderstorms and generates an electromagnetic pulse. The path from the cloud to the ground is extremely fast: about 30 milliseconds.
It is common for lightning to fall into the same place, and there are also findings as to why these gigantic electric shocks in a plasma state always choose to fall into the same places.
One of the institutions that decided to investigate it was the University of Groningen in the Netherlands and there findings were published in the journal Nature. In short, the researchers found that negative electrical charges in the clouds do not “strike” in a single beam.
On the other hand, the first ray to fall will generate a kind of channel, called a “needle”, which, once the discharge is finished, maintains a trace of plasma, which facilitates the arrival of another ray. These needles leave a kind of trail for the rays that are about to fall, which encounter less resistance on the path already traced by the first the beam. Therefore, the same point has a great chance of receiving several consecutive electric shocks.
