11. With the critical density demarcating a universe that eventually crunches from one that simply expands. 12. One prediction of the inflation model is that the universe should have a critical density . 13. The key is having an inviting setting that brings a critical density of people down to the water. 14. The critical density of the universe is dependent upon the rate at which the universe is still expanding. 15. Although, it is now understood that the critical density has been measured and determined to be a flat universe. 16. In common designs, it reaches a critical density when discharged to about 75 % depth of discharge, or below. 17. So there is missing cosmic energy, they said, but not on the order of 80 percent of critical density . 18. :: : And below a critical density , the atmosphere will behave sufficiently like a vacuum or a sparse plasma. 19. These forests constitute the ideal environment for numerous species, in particular birds, with critical densities of woodpeckers and owls. 20. The gravity of a critical density should slow expansion to a kind of coasting equilibrium between collapse and vanishing infinity.
