Yes, but to math make the Big Bang or did the Big Bang make the math? I
don't know and I'm not going to pretend that I do.

1961 is pretty recent and in that year Landauer discovered that the
absolute minimum energy it takes to erase one bit of information is
ln(2)kT , k is Boltzmann's constant 1.381 X10^-23 J/K, and T is the
temperature of the computer in degrees Kelvin. In 1972 Bekenstein
discovered that the maximum amount of information you can put inside a
sphere is proportional not to it's volume as you might expect but to it's
surface area, and it's 2PI*R*E/h*c*ln2 where R is the radius of the sphere,
E is the mass-energy inside the sphere h is Planck's constant and c is the
speed of light.
