I went ahead and moved this discussion to New Theories.Your new topic appears to be related to atoms and not planets, so I didn't merge the two topics.As RD had mentioned quite a while ago, if the core is denser than the crust, then the acceleration due to gravity does increase slightly as one descends through the crust, or deeper into the ocean. We currently do not have any technology that would allow drilling into the mantle, or core of the planet. See:https://en.wikipedia.org/wiki/Gravity_of_Earth#Depth
I'd already sorted the Ve calculations I was more interested in a plot of Ve from the centre of gravity.
