I love these theories that seem to explain things and then fall short just like that. "So how does an airplane fly upside down?" An the theory goes out the window. Relevent XKCD: https://xkcd.com/1145/ https://xkcd.com/1145/ "So why the sky is not violet?" Actually things like that is what got me interested in physics. My physics teacher asked "so does lightning strike from the sky, downwards". Everybody in class agreed. We all "know" this. We all "seen" it in cartoons. We were learning about electricity (electrons) at this time. "But if electricity is electrons moving, ground obviously has more electrons that the sky, lightning must go from ground to the sky". I was so fascinated about actually "learning" something new. Remember running home to tell my father how clever I was now. Lightning is much more complicated that this obviously: https://youtu.be/RLWIBrweSU8?t=77 https://youtu.be/RLWIBrweSU8?t=77
