Surprisingly it's the Planck Area that's important not the Planck volume
​ as you'd intuitively think​
. The ultimate limit on the amount of information that can be
 inside a sphere is proportional to the sphere's are
not its volume;
the formula is  I= PI *R^2 *c/G*h*ln2
, where R is the radius
c is the speed of light, G is the gravitational constant
 h is Planck's constant
​ and ln2 is the natural logarithm of 2
​...). ​

at works out to 4 Planck Areas (1.6* 10^-69 square meters)  to encode one
bit of
