The force of the implosion will set off nearly the same pressure wave regardless of the materials. The materials will not determine the pressure wave beyond what depth it occurred at, ergo at what force.
After that the pressure wave resulting from the force is basically the same, it would depend more on volume and very little on materials.
When testing this at UW they had a 1/3 scale model in the pressure chamber, it failed well before the design depth, the result was Stockon destroyed every pressure sensor in the chamber from the implosion and had to replace them all.
It matters because Biden wasted precise American resources for a political cover of his son’s criminal activity. People who continue to dismiss his actions, regardless of the reason, are allowing our government to become even more corrupt.
I despise Biden and what he has done, but assuming this is some cover up for Biden when there is legitimate coverup evidence to be focused on is silly.
There are conspiracies out there, but everything is not a conspiracy.
