No, going deeper into the moon would <i>reduce</i> gravity. This is covered by the <i>shell theorem of gravity</i>, proved by Newton centuries ago. If you have an evenly-distributed mass shaped as a hollow sphere, then two things follow:<ol> <li>Outside the shell, the gravity is the same as if the mass was all at the center of mass point. <li>Inside the shell there is no gravity. All the gravitational attractions to the various parts of the shell cancel, regardless of where you are inside the hollow shell. </ol>
