Then I don't get the implication you see for the cosmological constant.
I find this wasteful. Instead of guessing at why the numbers don't work, I think we should be using our resources to find out why the numbers don't work. How much mass is missing? (I used to know.) How can we be missing (failing to observe) it? How can we discover it? Or is there a problem with the theory and we haven't yet realized it?
When we go back to forcing our data to fit our model with cosmic constants and such, the data are speaking and we're not listening. Or, as a famous smartass once wrote, "When the facts do not fit the theory, they must be disposed of."
