I have perhaps an ignorant question...<p>So the earth&#x27;s mass essentially causes a distortion in space time which causes gravity. My question is, even to the smallest nth degree, why don&#x27;t we observe other objects on earth with their own gravitational field?<p>For example if I take a giant ball of lead, and I move it around in a vacuum but on earth, why doesn&#x27;t it act like it has its own magnetic field and cause dust (again, in a vacuum) to be disrupted as the field passes over them?<p>Has this effect been observed (under controlled conditions)?
