  "abstract": "In cyclic cosmology based on phantom dark energy the requirement that our universe satisfy a CBE-condition ({\\it Comes Back Empty}) imposes a lower bound on the number $N_{\\rm cp}$ of causal patches which separate just prior to turnaround. This bound depends on the dark energy equation of state $w = p/\\rho = -1 - \\phi$ with $\\phi > 0$. More accurate measurement of $\\phi$ will constrain $N_{\\rm cp}$. The critical density $\\rho_c$ in the model has a lower bound $\\rho_c \\ge (10^9 {\\rm GeV})^4$ or $\\rho_c \\ge (10^{18} {\\rm GeV})^4$ when the smallest bound state has size $10^{-15}$m, or $10^{-35}$m, respectively.",
