Writing a googolplex would take about 1.51×10^92 years, which is about 1.1×10^82 times the accepted age of the universe. Adam and Chuquet used the long scale of powers of a million; that is, Adam's bymillion (Chuquet's byllion) denoted 10^12, and Adam's trimillion (Chuquet's tryllion) denoted 10^18.
The measured spectrum confirms a flux suppression at the highest energies. Above 5.3×10^18 eV, the ``ankle'', the flux can be described by a power law E−γ with index γ=2.70 ± 0.02 (stat) ± 0.1 (sys) followed by a smooth suppression region. For the energy (Es) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find Es=(5.12±0.25 (stat)+1.0−1.2 (sys))×10^19 eV.
