So I have seen the never ending clash between those who believe in a Spherical Earth and those who believe in a Flat Earth. It thus made me wonder what a Flat Earth would even be like. One of the things I wondered and want to find answers to is its gravity, specifically its nature.
For this question, I will give some context.
- The Flat Earth has the same overall mass as the Earth we know.
- The entire surface area of the Flat Earth is equivalent to the surface area of Earth at Ground Zero. Of course, due to mountains and cities, there might be some uneven ground, just like our Earth.
- The other end of the Flat Earth is just ice and rock. This will weigh the same as the mass of the rest of our Earth (i.e. Core and Mantle). Most of this is evenly spread out, just like the other side.
So, something like this picture below:
With this in mind, what would gravity be like on this Flat Earth? It will certainly not be 1 g anymore, that is for sure. Would there even be gravity? Can the structure even hold?
