  By taking seriously the limits on observability which come from combining
relativistic quantum mechanics with general relativity, Ed Jones has shown that
the current measurements of the cosmological constant density
$\Omega_{\Lambda}\sim 0.7$ imply that the temperature scale at which it becomes
possible to discuss cosmological models is $\sim 5 Tev$ ($5.8\times 10^{16} \
^oK$). This is self-consistent with the assumption that the number of Planck
masses which make some sort of ``phase transition'' to this state is
$N_{Pk}\sim 4\times 10^{61}$. We review Jones' argument and the {\it bit-string
physics} calculation which gives the baryon-photon ratio at nucleosynthesis as
$\sim 2/256^4$, the dark matter-baryon ratio as $\sim 12.7$, and hence
$\Omega_m \sim 0.3$, in agreement with current observations. Accepting these
values for the two energy densities $\Omega_{\Lambda}+\Omega_m \sim 1$ in
accord with recent analyses of fluctuations in the CMB showing that space is
flat to about 6%. We conclude that experiments with particle accelerators in
the 5-10 Tev range must either show that current theory can adequately describe
the currently observed structure of our universe or force us to revise our
ideas about physics at a very fundamental level.
