But I was just thinking, is it at all possible for there to be parts of the ocean where there is no bottom seabed? Is it possible for the ocean to span downward all the way to the opposite side of the globe?
no. No hole deeper than a few dozen kilometer in the rock that makes up the crust and mantle of the earth could possible remain open by the strength of rocks that makes up its walls. the hole would immediately close under the overwhelming pressure of surrounding rock.
this is true even if we assume rocks remain as cool and stiff as on the surface all the way down, and not soften and weaken under rising pressure and temperature as rocks do deep inside the earth.
this is the fundamental reason why pseudoscience fictions presupposing large voids existing deep inside earth, much less a hollow earth, is bunk.
