Yes but if we're talking about the maximum about of information that can
fit inside a sphere then we already know what M must be in the above
formula, it's the amount of matter needed to form a Black Hole of radius
R, and the formula for that is
​
M= c^2/2G *R
​
,
​
where G is the gravitation constant and c is the speed of light that is
also a constant
​. S
tick
​ing​
the two formulas together and you get
I = (a constant) * R^2.

​So t
he maximum information inside a sphere is proportional to the sphere's
surface area not its volume.
​ So the information isn't really in the sphere it's on the sphere.​
It almost make me think that one of our 3 dimensions
​is​
phony.
