Yes, it takes time, otherwise it would exceed the speed of light, which is a gigantic no no. But that's why I said "almost". I would call it more of a propagation.

By the way, the largest Plutonium bomb ever built was British with a yield of 750Kt

I remember that the efficiency of an atomic bomb is low. All we need is 10% for our answers to agree. Actually, that sounds too high to me. I think I remember a figure of 4% for the first atomic bomb.

An electric wire is a bit like a pipe crammed full of peas. Push a new pea in one end and one falls, almost instantly, out the other.

Interestingly, in parctical terms, it would require a huge amount of Uranium. The high figure is because Atomic bombs are not very efficient. In the first atomic bomb which had more than 50Kg of Uranium, only 0.7g was converted to energy. So a 50Kg Uranium bomb releases the same energy as a 3.5g...

It takes a massive amount of force to generate the density necessary for the creation of a black hole.
