Also there is a huge difference between a nuclear chain reaction and a bomb so I have no idea why you are even trying to drag that into our conversation.
Wow.
Simply.
Wow.
http://en.wikipedia.org/wiki/Nuclear_chain_reactionThat you would even attempt to claim that a nuclear chain reaction has nothing to do with a nuclear weapon is simply mind boggling.
I don't know where you are from, what your education is or why you persist in exposing your ignorance but please, stop embarrassing yourself. At this point, I really have to consider that I should disengage from this because it is fundamentally unfair to engage in a battle of wits with the witless.
REALLY? no connection between a nuclear chain reaction and a nuclear bomb?
REALLY?

Yeah really. Take that boot out of your ass and tell me what is so scary about a helium nuclei resulting from radioactive decay hitting another atom and triggering another decay. I do not know about you but we did that in basic physics class and I dont remember any mushroom clouds.
It is not the nuclear chain reaction that is the scary part. Its the mass to energy conversion better known as E = MC^2
When will you get this through that thick skull of yours. Perhaps I should make a wikipedia page for you?
