Lightning is a Huge Mystery

As common as lightning is, it still sparks considerable confusion among scientists. The basics are understood, but no one knows how lightning makes x-rays.

Lighting moves in "steps," and after each step x-rays are released. No one knows why or how -- lighting is too cold to create x-rays. How can we possibly not understand this? We have so much technology and we don't know how friggin' lightning works?
