Abstract: (arXiv)
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 ΩΛ0.7\Omega_{\Lambda}\sim 0.7 imply that the temperature scale at which it becomes possible to discuss cosmological models is 5Tev\sim 5 Tev (5.8×1016 oK5.8\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 NPk4×1061N_{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 2/2564\sim 2/256^4, the dark matter-baryon ratio as 12.7\sim 12.7, and hence Ωm0.3\Omega_m \sim 0.3, in agreement with current observations. Accepting these values for the two energy densities ΩΛ+Ωm1\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.
