Was the Big Bang Really the Beginning?

The headline declared "The Big Bang Wasn't the Beginning, After All" and in the accompanying article astrophysicist Ethan Siegel made the definitive statement that "the Big Bang is not the beginning of the Universe!" That seems to settle the question once and for all, and to put all of us theists in our place. That declaration should shut the mouths of theists who keep insisting that the big bang is the beginning of the universe and that the origin of the universe requires some kind of transcendent cause, a cause that looks a lot like the traditional view of God. It appears that the headline and the decisive pronouncement by Dr. Siegal has made the argument for God from the origin of the universe null and void. That is, unless you actually read and understand the article itself.

I recommend you do read the article. It is a very nice synopsis of the historical development of our current understanding about the origin of the universe. In the article, Dr. Siegal describes the observation that space itself is expanding and cooling, leading to the conclusion that the universe was once much more dense and hot in the past. He recounts the "breathtaking confirmation" of the big bang made in 1964 by Arno Penzias and Bob Wilson, who discovered the Cosmic Microwave Background radiation, the residual heat from the hot big bang. He steps us back through time as the universe becomes hotter and denser and we encounter three milestone events, a time when it was so hot that neutrons and protons could not form nuclei, a time when matter and antimatter could spontaneously form from energy, and a time when a quark-gluon plasma existed with no individual protons or neutrons. He affirms that all of these events have been confirmed to be true in that we've observed the physics that explains these events in the laboratory, and made observations that remarkably match theoretical predictions.

Is the Evidence for the Big Bang Really Weak?

When I was a teenager and young adult I read a few books by Christians who wrote about the subject of science and Christianity. All of those books promoted a young earth that was only a few thousand years old and questioned the validity of scientific discoveries and ideas that led scientists to believe the universe and earth were billions of years old. As a young adult I did not really have the knowledge or resources to ascertain the strength or validity of their arguments. However, when I was working on my Ph.D. in particle physics I decided that if I were to eventually be a scientist, as well as a Christian, then I should do my own independent study of what the Bible says about science and the evidence from nature, and consider the strength of the arguments I had been presented. By that time in my life I had taken formal science, theology, and logic classes and had the tools to personally investigate the truth about this subject.

Every once in a while something will come up that reminds me of my journey as a young adult to find the truth and prompts me to share my findings with others. As I have stated in my last few posts, a reader of my blog directed me to a few videos by young earth creationists and reiterated some of the arguments they made about the scientific evidence regarding the age of the universe. As I watched those videos and read the questions posed, I was taken back to my days when I was first investigating these subjects. Though the subject and context are different, the statements made on the videos that tried to cast doubt on the scientific discoveries about the age of the universe follow the exact same pattern used by proponents of a young universe decades ago. If you are a Christian or non-Christian, young earth creationist or old earth creationists, and you want to know what is the truth, not simply be indoctrinated, then it is worthwhile to consider these kinds of videos and the validity of their arguments. As a Christian, I follow and worship the God of all truth, so I have no concerns about investigating the truth and seeing where it leads. Only someone who is so indoctrinated in their beliefs that they don't care about the truth would be reluctant to critique the evidence for their beliefs to see if it stands up to facts and reasons. So let's investigate some of the details and tactics used by speakers in these videos to promote a young universe in an attempt to understand both truth and the God of all truth.
