Ok, so let me clarify: a planet that overcame all structural problems with being planetary size, I.E. collapsing into a ball.
- What would be the gravitational strength on a flat planet with the diameter and mass of, say, Mars?
(I believe Mars has .38 surface gravity of Earth). This theoretical planet has sufficient dense materials to have the same mass of Mars while only being disk-shaped.
The outer edge of the planet is flat (think of it like a massive coin). My understanding would be that the gravitational strength on the edge of this coin would be .38 the strength of Earth.
but what would the gravitational pull if you were standing on the center?
and ditto for different places on the flat surface?
I've see the Vsauce video, btw.
- Also, would rotating the planet help take stress off of any necessary structure support built into the planet to keep it from collapsing into a ball shape?
I'm talking rotating like a record player, not like a coin.
