The titanium sphere design would be too big and heavy to accommodate five passengers.
Huh?
The wall thickness needs to increase the bigger the sphere is in order to resist the water pressure. A one person sized spherical submersible already weighs around 12 tons. How heavy would a sphere three times the diameter be? Then you need x times the amount of boyant foam. I'm not sure if spheres that size can be forged and tested.
It’s over they found “presumed human remains” from the wreckage site. You can all rest easy now.
Huh. So maybe they didn't evaporate instantly? The porthole window is missing from the front section, so perhaps they pried it open and tried to swim up!
I've literally thought about this loads. I think 20 miles below the water could become ice. But then you are closer to the earth's mantle so the water would start to become more warmer instead of cold like it normally is at the bottom.
Water is densest at 4C.
At 1 atmospheric pressure, the more you increase pressure the less chance of boiling or frezing, hence no phase change
So, how deep would an ocean have to be before the water itself is severely affected by the pressure? What would happen to it, would it freeze, boil, turn into plasma, be ejected into another dimension?

We don’t know what exactly will happen, but here are some things we know: The earth’s radius is about 6000 km and the temperature at the core is over 6000 C, so we are looking at an average temperature gradient of 1C/km, and a pressure increase of 100x atmospheric per km; the freezing point of water decreases by just under 1C with a pressure increase of 100 bar; but the water temperature under sea initially decreases significantly before increasing again because of the proximity to the core, and we don’t have good models or real data for predicting exactly how the temperature would change.
So, depending on the temperature and pressure combinations reached with increasing depths, we could either first see a transition to ice VII or directly or subsequently to supercritical or maybe superionic (only hypothesized) forms of water at very high temperature/pressure combinations.

Well, notwithstanding how media loved to replay the video of Stockton Rush showing off a gaming controller to the journalist’s snickers, he wasn’t wrong that all that doesn’t matter at all, and that the only thing that matters is whether the hull is capable of resisting the pressure.
Unfortunately, he happened to be wildly wrong in the design of that single most important thing.
