Well, I agree with Weinberg’s analysis as I heard of the cosmological constant problem before. Quantum field theories predict this would be 10^123 of its observed value. If this value was higher than its present value, galaxy formation would be prevented in the early universe. However, there are other solutions to this problem, such as invoking eternal inflation: stanford.edu/~alinde/Ribozyme;
Probably no less an authority than Steven Weinberg in his article, “Life in the Universe,” Scientific American, October 1994.
The pertinent quote is “Life as we know it would be impossible if any of several physical quantities had slightly different values…One constant does seem to require incredible fine tuning.”
The constant Weinberg is referring to is the energy of the Big Bang which he quantifies the tuning as one part in 10 to 120th.
Yes, Ribozyme, if the energy of the Big Bang were different by one part out of
10000000000000000000000000000000000000000000

there would be NO life anywhere in our universe.

It is not the energy of the big bang, but it is the vacuum energy of the universe. This is describe quite well in layman’s terms in chapter 2 of The Cosmic Landscape: String Theory and the Illusion of Intelligent Design.
