(To be clear, I’m more interested in the reach and scaling of gravity.)

If we were to suddenly double earth’s mass, but not it’s size, would it’s field double in size (I assume strength as well), to the extent that if I were to measure this increased gravity at the same place I measured earth’s normal gravity, it would simply be double? If so, the least measurable point of both gravitates should also be the same?

Just wondering if there’s diminishing returns or if mass and density affects a gravity field the same regardless of whether it’s an asteroid or a billion Solar Masses.

Feel free to share any views I’m not taking into account in regards to gravity fields.

Thanks

    Gravity is not exponential. It is linear with mass and inverse square with distance.

      Hey @Jeredin@lemm.ee

      This one, @FlowVoid@midwest.social, has the correct answer…

      So, don’t believe in the crackpot idea that it would be exponential

          I did make I have made many mistakes, much worse than this one and on many occasions. I would say : don’t be so hard on yourself since it’s important to forgive ourselves.

          I do believe the following correction should be made again to your text though :

          Gravity is an [edit: inverse squared] function, so it gets weaker at an exponential a squared rate as you move away from the source.
