I wonder if the visible universe is large enough to write down the exact value of BB(6).
replies(5):
The mass-energy includes ordinary matter, dark matter, and dark energy. Current estimates suggest the observable universe contains roughly 10^53 kg of mass-energy equivalent.
Plugging these into S ≤ 2πER/ℏc gives someting on the order of 10^120 bits of maximum information content.
S ≤ 2πER/ℏc
S ≤ (2 × 3.141593 × 3.036e+71 × 4.399e+26)/(1.055e-34 × 299792458)
S ≤ 2.654135e+124
S ≤ 10^120
So, no.
