I am trying to find an explanation to a planet in which the gravity is not constant, thus allowing some continents to be situated 2-3 km above surface while others are "grounded" on the surface.
The planet also has 2 kinds of rain because of the gravity:
- Normal rain: falls as in Earth from the clouds to the surface.
- Unusual rain (relative to Earth): from the surface up to aliment the continents that are above the surface.
I have read the question A planet with changing gravity, however I think it is different to this question.
Edit: The continents float due to gravity being different in certain part of the planet. There are not mere islands. It is like having Asia and Europe floating above ground while Africa, Antarctica, the Arctic and the Americas are grounded on the surface
Edit 2: As stated on the comment section to @Renan's answer, the explanation may be outside of Physics, Astronomy, etc as we know them, but not should not involve magic.
