An oceanic question

[Fireball]

^ Missing some elephants and a turtle.

Wait, I thought it was turtles all the way down?

The Challenger Deep is the deepest known area of the ocean.

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?

I am being dead serious, and not trying to offend or embarrass you or be mean.

I am honestly wondering where this thought on your part originated from as a possibility. 

The truth in reality, is that earth's core is molten. It is hotter than heck, and the only reason humans don't burn up on the surface, is because we have a crust that protects life from the core heat. But we have "plates" being of crust, that float on that molten core, and over time, those plates bump into each other and cause volcanoes and earthquakes. 

But it isn't Hollywood. It isn't a magical geological process that gets solved in an hour and a half or 2 hours. Geology and astrophysics are a study of over interaction over geological time over millions and billions of years.

Earth is only one example of the evolution of our solar system. But big gas planets like Saturn and Jupiter, do not have the same makeup as earth.

Actually, the inner core is solid, the outer core is what’s molten. The tectonic plates ride on a partially molten part of the mantle, called the asthenosphere, not on the core.

Yeah, my thoughts go in weird directions sometimes.

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.

You mean like planet Naboo in "Phantom Menace"?

My guess is if a hollow planet like Naboo existed it would be a clear indication that it was artificially constructed.

Nooo, they hold up the flat earth silly. But, yeah it's rooly rooly big turtles all  the way down.

Didn't they teach you anything at bible school? EG the tragic story about Christopher Columbus. On the way back to Spain, his flag ship The Santa Maria sailed off the edge of the earth. Chris and his entire crew were eaten by the first (and smallest ) great turtle***


***  Fact check:  Each turtle is of course bigger than the one above it. So naturally, the very last turtle fills the entire universe.

It's a great question, how much water lies below the crust of the Earth:

and, with it, life. What amazes me is that there are bacteria, via Darwinian natural selection, that have slowed their metabolism down to thousands of years for cell division to survive deep underground.
