Hi all! In the absurd hypothesis that we could take all water from earth's oceans and distribute it equally through the sky ceiling (as shown below). We have the point of view of an observer in the land. Questions: 1. We know that the water pressure rises as we come closer to Earth's core, so the "flying ocean" would have less pressure at its "bottom", right? 2. If the previous is true, would the pressure difference be considerably lower than actual seabed one? 3. If observer in land would be launched in the air, entering the "sky ocean" from the "bottom", would he be crushed by the seabed pressure as if it were submerging into the Mariana's Trech, for example? I know this is fairly nonsense but it's a scenario for a fiction. And I really need answers! :) Thanks people!
