Rigorous Science

A different artificial gravity: Ultradense material

+0
−0

Guests of this large space station enjoy Earth-like gravity (80-90% minimum).

How? Well the space station is so massive it has its own gravity. The disk shaped "core" is made with ultradense materials with an overall of 20-30 g/cm3 similar to Iridium or Osmium (the densest elements).

I thought that working with material with such density could provide decent gravity with relatively little amount of material so I tried crunching some numbers...

Turns out I suck at math. How massive/large does a disk with these density have to be to provide similar gravitational pull close to its surface? (Ignore edge effects and the core does not have to keep its own atmosphere, even if you can just provide some formulas it would be great since right now I don't have much time for this)
