Then, having grasped a bit of the theory behind the Cobalt Bomb, I considered your question:
Lam writes:
If the cobalt bomb exists, would you say that it would be the most powerful bomb in the universe? If so, how would you find out for sure?
And now for my Final Answer,Regis: If a cobalt bomb exists, it would be as dumb as two guys in a jail cell possessing hand grenades and squaring off to fight!
By no means would such a bomb even be seriously considered to be the most powerful bomb in the physical universe...but perhaps currently in our world,no?
Now...as to how I would find out....hmmmm....I could ask you, Lam!
