So uhh I tried plugging in the numbers that
the planet compression blog used in a calculator and this is what I got for compressing Earth into the size of a sugar cube.
So the blog used (3GM^2)/(5*radius)
Mass = 5.973e24 kg
Gravity = 6.67e-11
Radius of Earth = 6378 km = 6378000 m
Diameter of an average sugar cube = 1 cm
Radius of an average sugar cube = 0.5 cm = 0.005 m
0.005 / 6378000 = 7.8394481e-10 m
So plugging that in would be
(3*(6.67e-11)*((5.973e24)^2)) / 5*7.8394481e-10 = 1.8212796e48
And they had to subtract it by 1/10 for some reason so if I do that it would be
1.8212796e48 - 1.8212796e47 = 1.63915164e48 joules converting that to KiloFoe would be 16.39151639 KiloFoe
So if I did everything correctly that would mean this feat is 15.56649229x greater than Zetton destroying the solar system from Earth. So if this is correct than it would be a rather large upgrade to the mid tiers as Jack resisted being inside of Vacuumon and killed Vacuumon with the Ultra Bracelet.
Also I recently found out that Ace’s Ultra Guillotine has a statement of being several times stronger than Ultraman’s Dismembering Halo. So that’s another 3x multiplier in the scaling chain as at the time Ultraman and Jack were comparable.
