@suesa very interesting
I want to help strive to develop knowledge in steemit and happy to join you all.
and I am also happy to post a comment here.
I can catch your discussion on this post.
you tell about light and include lightning light.
my question is: where is the origin of light and lightning ?
I only know about clouds, because that's my subject matter at elementary school, and I know it happens because of the heat and can collect the clouds until the rain. but until now I have not found the science of the origin of lightning (lightning) and lightning.
I think you can answer that @suesa
thank you
