Gravity (and time) are only constant when measured from the same relative movement through the universe.
Constant is an illusion in the idea that we tend to think of everything moving toward or away, in a fashion, from us.
Indeed, my notion of gravity increasing as a result of increased mass is incorrect, as my relative motion did not change.
In fact, my motion decreased only relative to my immediate surroundings.
I ate to much.
