Hi Dean
Take 5 balloons , insert them one inside the other , different sizes , then blow them up so each one is a different globe inside each other , 5 cavities , 5 worlds , Young-Laplace equations.
As you measure the gravity,,,,in the smaller ones it will be less,,,,,,, proportionally .
Some thing to think about ? The Loony Tunes symbol pictogram ?
