Gravity decreases at a squared rate with distance. This seems to inversely correspond with the surface area of a sphere as it expands. As such gravity generally decreases proportionally to 1/r². Our universe has 3D volume but math explores the idea of 2D universes. I know it is not a reality that we deal with but I was wondering what rate gravity would decrease in an imaginary 2D universe. In a 2D universe gravity would expand as a weakening circle instead of as a weakening sphere of influence. As a circle increases in circumference directly with radius - instead of at a squared rate as does a sphere - does this mean that in an imaginary 2D universe gravity would decrease at a rate proportional to 1/r?
