hi
I'm new here (english is not my first language)
I wanted to express my thoughts on the orochi calc:
this calc is a low ball to orochi's feat
1) it does not take into account the most important part of what orochi did: he moved a portion of the Earth's core THROUGH the mantle (liquid!)
kinetic energy would be fine if the "bullet" goes through vacuum or air but here it is DIFFERENT! is crossing THE TERRESTRIAL MANTLE! this means that the frictional force that opposes the movement of the "bullet" and the earth pressure are tremendously enormous and cannot be ignored !!!
2) the object moves in the opposite direction to the earth's gravity, I have no idea how this works since the object is inside the earth itself, but I think that the earth's gravity still has some kind of influence
taking into account (1) the result would be several orders of magnetudo larger than that estimated here
