  Although experimentally accessible energies can not probe `asymptopia',
recent measurements of` inelastic $pp$ cross sections at the LHC at 7000 GeV
and by Auger at 57000 GeV allow us to conclude that: i) both $\sigin$ and
$\sigtot$, the inelastic and total cross sections for $pp$ and $\bar p p$
interactions, saturate the Froissart bound of $\ln^2 s$, ii) when $s\rightarrow
\infty$, the ratio $\sigin/\sigtot$ is experimentally determined to be
$0.509\pm 0.021$, consistent with the value 0.5 required by black disk at
infinite energies, and iii) when $s\rightarrow \infty$, the forward scattering
amplitude becomes purely imaginary, another requirement for the proton to
become a totally absorbing black disk. Experimental verification of the
hypotheses of analyticity and unitarity over the center of mass energy range
$6\le \sqrt s\le 57000$ GeV are discussed. In QCD, the black disk is naturally
made of gluons; our results suggest that the lowest-lying glueball mass is
$2.97\pm 0.03$ GeV.
