Based on measurements of the gravitational effects of dark matter and luminous matter in the distant universe, astronomers have measured Ω (that is, Ω_{DM} Ω_{B}) to be about 0.3. Meanwhile, based on detailed observations of distant Cepheid variables and Type Ia supernovae, astronomers have deduced that the expansion rate of the universe is increasing. That means that Λ is greater than zero. Finally, based on careful study of the cosmic microwave background, astronomers have confirmed that the universe has a flat geometry, meaning that Ω Λ = 1. Carrying the precision of these measurements to one decimal place, the current measurements show that Ω = 0.3 and Λ = 0.7. If these numbers hold true, then our universe is destined to expand forever and there will be no Big Crunch.
