Much heard of in math, numbers upward of 100 digits
are rarely seen in physics - now one has surfaced it's :
The Entropy Of Everything -- Mostly Black Holes.
and is reckoned as ~ Ten to the 102nd power
||High Energy Physics - Theory |
Abstract: Standard calculations suggest that the entropy of the universe is dominated by black holes, although they comprise only a tiny fraction of its total energy. We give a physical interpretation of this result. Statistical entropy is the logarithm of the number of microstates consistent with the observed macroscopic properties of a system, hence a measure of uncertainty about its precise state. The largest uncertainty in the present and future state of the universe is due to the (unknown) internal microstates of its black holes. We also discuss the qualitative gap between the entropies of black holes and ordinary matter.
