So recently i have bean thinking about earth's gravity, and i have more of a theoreticall question, for people who understand more then me. What if some one reacreat a small round sphere, whit the same elements that are found in earth, and apply the same rotation speed, layers and magnet like north and south pole, but just smaller in scale. Including the magma close to the real thing but smaller, like a baskerball. Would it create the same gravity ore earth is mutch complex then this ?
