Hi RobA,

What are the precise predictions? 75.00 +/- .01? What observations do you refer to when you say there is agreement? In your mind, what level of agreement is necessary to make the ratio matter?

What does the BBT theory predict as to ratios of hydrogen, helium and deuterium in relation to each other element of the periodic table? Is there a similar level of agreement? As in within the same, I will assume very small, error bars?

Should agreement matter if it only relates to hydrogen, helium and deuterium; even if there is no agreement in relation to the other elements?

Also, your articles refer to "young" as defined by models of what young means. I was more asking about what those models said and what they were based on.

Please though, remember the other questions:

How is the big bang a falsifiable theory?
Why would one believe it solely because no one has offered a better theory?
What are the other measures of the age of the universe you refer to?
How does one know how "far out" a galaxy is?
