Nuclear detonation
A microsecond into detonation

     This is an atomic blast about a millionth of a second into detonation, one of the most horrifying pictures I have ever seen.  The little black figures in the foreground are Joshua trees, which survive only in this part of the world.  So this monster grew from nothing to more than a thousand feet tall in less than a millionth of a second.  I wish everybody knew how powerful these weapons are.  I harbor an illusion that such awareness would lead quickly to their banishment.  However, a search of comments on the web in response to this image shows that many people, boys probably, think nuclear weapons are cool or awesome.  So sad.
