Possible confirmations in real world/universe

[dreamliner]

The current scientific knowledge does not see sunken continents as a possibility.

However, it may change in near future: https://www.sciencenews.org/article/geol...underbelly

That would be cool, but the synopsis doesn't mention sinking, only sliding.

That's why I said "may change".

Logically, for a continent to sink;
1- a giant hotspot beneath it should form for some reason
2- that hotspot should melt the substructure
3- with the help of the continent's weight, and gravity, the melted material should be transferred to other/neigbouring locations "gradually", so that when the substructure is emptied "gradually", the continent can sink "gradually"

It should also be noted that, gravity is not uniform and constant all over the earth: https://en.wikipedia.org/wiki/Gravity_of...nt_gravity
