The Cosmogical Constant, the Vacuum Energy

The values of the cosmotical constant are different from place to place in the multiverse. If it's very large, then there's no time for intelligent beings to exist. And intelligent beings will find themselves in regions where the cosmota constant is small. But we don't know whether whether the antecedent is true. We don't know if there is a multiverse out there. So even though the reasoning is solid, we don't knows if it's the correct reasoning for our universe. But it could be.
