It is precisely gravity when it is not overwhelmed by the stronger
electromagnetic force. For example, if chemical bonds were weaker and all
matter was a liquid, you as a liquid, would rise or fall until you were at
the layer of all the liquids with your same density.

Yes. You would "weigh" appromiximately 1.2 grams more per kilogram of your
actual mass if you were in a vaccuum.
