If it was a higher power, stars as small as our sun would be unstable
and the stable periods for even smaller stars would be much shorter.
Perhaps a few million years rather than billions.
The two long range forces we know about, elecric/magnetic and gravatic,
both have the same r^2 dependancy. Similarly, light intensity from a
point source, etc, decays by the same rule. It looks like a kind of
geometry thing.
BTB. The short range forces, nuclear strong forces, have very short
ranges and much higher r^n dependancies.
The firce inside a sphere is zero, same as the E field inside a faraday
shield. That this is important I guess, but I have no idea why, but it
is only true because the dependancy is exactly the power of 2.
• Only God knows. You will have to ask Him why the speed of light is a constant, or to explain turbulence.

How true is that! For every answer we find it only leads to ten more questions, which lead to ten more and on and on.  Myself I can't tell you why it's the square and not the cube either.  However I think that is was Sir Isaic Newton who came up with this ratio by calculating the rate at which objects accelerate on there path to the ground.  But don't quote me on that.
Also I know the true force of gravity is something of a debate in modern physics right now. If string theory is ever proved our understanding of gravity will completly change
