Yo,
What's the basic calculation for how much gravity is created by how much mass? I'm curious of this in regards to how big an asteroid or comet, or anything for that matter, has to be to have practical amounts of gravity with regards to human influence. Specifically, im wondering if a cosmological, or artificial, lump of something could be used as the core of a spaceship for the purposes of creating gravity on that ship.
And don't worry about giving me hard or advanced maths, I'm just after getting a general understanding for some sci-fi creative writing I'm working on. So giving me measures and scales in the way documentaries do will be fine.
"A lump of lead the size of a sports stadium would have 0.2g", or "a solid iron asteroid the size of Ohio would be like walking on the moon".... You know the sort of thing.
Cheers
