Yeah once past the sun a few dozen times all the ice will have sublimated

Detailed photographic analysis of the last two cometary flybys didn't show any ice geysers, or even geyser vents.

Then, their lander didn't work because it was designed to spear into slushy ice, not solid rock, which is what they found.

Watching the televised post-mission conference, you could see how shaken the mission scientists were. Their models had failed to predict pretty much everything they'd observed.

The structure of atoms was theorized long before they could be observed with electron microscopes; there is no major deviation from the original theory. And creating atomic bombs depended on splitting the nuclei of Uranium 235 with neutrons; this mechanism is obvious due to its having been observed repeatedly.

The structure of the earth’s core was deduced from studying seismic waves and how they pass through the area of the core. Not as useful as observation with the eye, but not an unscientific start.

One thing that magma depends on to form is dissolved gases, particularly sulfur compounds, carbon dioxide and even water. Another is decompression in the asthenosphere, a layer of the upper mantle that is solid yet plastic.

Phenomena like this usually happen at fault lines; those are not conduits for a giant molten mass underneath the ground to pass through, but areas where compression and decompression happen for these phenomena to occur, otherwise we could have volcanoes everywhere.

True, but based upon so many other things scientists have 'deduced' through modeling, mathematics, and limited sensory data, I wouldn't be at all surprised, that in future, we discover that the cores of celestial objects are entirely different from what has been theorized.

It’s certainly possible.

I just used the atom as an example of what they got right via calculation without the benefit of direct observation. There are still real scientists out there, ones that resist the buyout/co-opt by governments.

Earth hides most of its water in its interior. Earth has roughly two ocean in its mantle, and 4 or 5 in its core.

Probable answer to the question, "Where is all the water from Noah's flood?".
