This is entertainment that was provided by the Creator. He has created the infinitesimally small and the unimaginable greatness of our existence. Every digit was landed in the right place with no remainder. It was created in this way to keep us humble and to see His glory in His design. And it is awesome!
I have not read the publication under consideration but I do feel that the consideration of the subject "The First Three Minutes" has great value. First, just the process of considering the subject humbles us since we may never get to an absolute answer. As in calculus we take the limit and get close to the absolute value but not the absolute value itself. Look what we do get however; really useful information. If we are scientifically honest we will be Humbled by considering the subject and humility leads us to realize that we don't know it all; that we need to continue to search for answers by continuing to ask questions. This process leads to getting answers along the way. These incremental answers have spawned some of the most useful technology of the 21st century.
In my early days of system integration and debug there were many times when the machine went south fast and we were left with the post error overwritten data fields and lost program addresses. In every case, we had to consider what might have happened and then set up some tests to mimic the educated guess at the cause. Then (if we were lucky) when the machine failed again, we had some trace data and logs to help us narrow it down. Without being able to recreate (pun intended) the original event it would be near impossible to be sure what happened. Repeating the conditions where the system failed is easy, repeating the conditions of the big bang is much harder. We are left to guessing and theories.
The laws of thermodynamics are fairly clear that energy is not created or destroyed. The "big bang" theory supposes that "somehow" all of this energy suddenly became available to heat all of this stuff up to temperatures in the thousands of degrees. Or lots hotter than that. So where did all of this energy suddenly appear from? And, for that matter, where did all of the stuff that was heated up come from? Here we have an instance where possibly a huge ball of plasma with enough mass to create hundreds of stars and planets suddenly happens to appear. That sounds a whole lot like "spontaneous generation", which is a concept that many in the scientific fields have problems accepting.
I have read Hawkings books and looked into the basic theories and how they relate to each other. While they are an interesting way to look at how the Universe we have today was formed, they are still only theories.
I know from years of solving engineering problems that you will never find the source of the problem if you chase the symptoms. Nearly all of the theories proposed are trying to explain symptoms by speculating how the beginning event began.
Since most of the ideas are not testable, they will never be answered to any degree of certainty. They are however very entertaining.
