>>20580945this matches up quite well with
another calculation
the density of the earth's core is 13g/cm^3 and is made of nickel
the natural density of nickel is 8.9g/cm^3
that's a 46% increase in density of nickel at 52700000 psi
nickel is twice as light as plutonium (not included)
Fat man would have only caused a .02% increase in density (less than adding a single neutron)
TNT would have to be at least 250000 times stronger or earth would have to be 250000 times denser for nukes to work
225000*2000=450000000psi
240000000/11308=21000psi
13/8.9=1.43
(1.43-1)*100=43%
21000/52700000=0.0004
0.0004*43=0.02%
