[Note by rerev: the following post contains pitiful errors of many different kinds; however they've been left unaltered] The size of plain H explosion depends on the amount of H and 0 , they have just told everyone that the blasts at Fuchshima were Hydrogen explosion I not confusing anything , I am perfectly aware of what an H bomb is supposed to be, it is to be disregarded considering the source. I’m sure they were bored of using TNT, if its an experiment worth doing at school then I think it’s an experiment worth doing on the mega scale . Also such experiments could play a role in feasibility studies for Terraforming other worlds.
As for real research it Nuclear explosive potential, Such experiments would have continued and been elaborated upon to this day in the search for explosive potential. They also probably started a lot earlier and the official story of the invention of any enervation are always complete fiction, see the social Network , or Darwin not have clue about evolution till he travelled to the Galapagos islands , or the Bill Gates Story. The story of the of the German bloke not releasing he split the atom if it hadn’t corresponded with some Jewish woman who had fled Nazi Germany, there is always a story and hero
It would seem to me that the basic idea of one atom becoming two smaller atoms plus a release of energy is essentially an increase in volume and a release of energy regardless of the scale sounds like explosion to me though I know not how exactly an explosion is defined.
My main problem with the notion of a nuclear explosion is that though I think it logical that heat and pressure in excess may crack atoms and force them to increase in number and so volume and release some or even all of there energy , but the explosive force would cause the pressure to drop from the first moment of maximum heat and pressure required to start to the crack of atoms, so the atom cracking would not continue, it would self extinguish itself before it gets started , It would seem to me that that a real nuclear explosion may be possible in a confined space as to maintain the pressure. This clearly would not be weaponizable but it could allow us to create controlled plasma style explosion and to some degree study them.
Beyond this, bursting out of the confined space or by means of releasing it from , it clearly would become increasingly difficult, but it remains possible surly that anything that you can do in small amounts slowly you can do in large amount quickly up to instantaneously.
It remains plausible to me with the correct set up you could provide enough heat and enough pressure for long enough to get significant explosion , involving hydraulic clamps and implosions and such , bit of experimentation I am sure you could get it to go bang .I think they probably would have tried everything they could to get it explode, throwing everything from neutrons , electromagnetics ,sound and the kitchen sink . imagine if you do get it to work and all the other important nations and the rest of the elite think it’s a hoax. These people always win because they have the good sense to back both sides , regardless of the hoax the research into the possibility of nuclear explosions and their potential for weapon ization would have continued in my view and in all probability does to this day, but I don’t think it has anything or is very loosely related to the official science fed to the public fission , fusion and all that .
