What is Lightning?

     Lightning is a natural phenomena that has fascinated humanity for all of our existence. Once thought to be the fury of angry gods in ancient times, lightning is now known to be a giant spark that can be five times hotter than the surface of the sun either mid-air or from the air to the ground made up of plasma. Even after studying the phenomena for thousands of years while we have learned a lot, we still don't understand it completely.
