I still disagree with Planet Level, the very specific Solver ability shown to have imploded the core was previously shown to "erase" matter (like some sort of localized black hole), as we see in Uzi's fight with N, so I already don't see how it applies to AP.
And about the first explosion/implosion, why are we assuming the epicenter of the implosion was in front of Nori and Yeva's faces?
It's stated repeately the core imploded, so that severed arm must've travelled the entire distance down to the Earth's core, whatever Nori and Yeva tanked, shoudn't be at the same paygrade as being in the actual epicenter of the core's implosion (you know, in the center of the planet).
Same thing for Uzi, she didn't even remotely fall near enough to Cooper-9's core for us to say she tanked the implosion at its "epicenter".
