The Flatness Problem
"Another serious challenge to the big-bang model is called the flatness problem. The expansion rate of the universe appears to be very finely balanced with the force of gravity; this condition is known as flat.
If the universe were the accidental by-product of a big bang, it is difficult to imagine how such a fantastic coincidence could occur. --Big-bang cosmology cannot explain why the matter density in the universe isn’t greater, causing it to collapse upon itself (closed universe), or less, causing the universe to rapidly fly apart (open universe).
--The problem is even more severe when we extrapolate into the past. Since any deviation from perfect flatness tends to increase as time moves forward, it logically follows that the universe must have been even more precisely balanced in the past than it is today. Thus, at the moment of the big bang, the universe would have been virtually flat to an extremely high precision.
This must have been the case (assuming the big bang), despite the fact that the laws of physics allow for an infinite range of values. This is a coincidence that stretches credulity to the breaking point. *Of course, in the creation model, “balance” is expected since the Lord has fine-tuned the universe for life."
