In Tying Oneself in Knots for Jesus, Part 1, I addressed William Lane Craig’s argument for the existence of his god, the Kalam Cosmological Argument, particularly how it is dependent upon how time works. The argument, goes something like this:
- Everything that has a beginning of its existence has a cause of its existence.
2. The universe has a beginning of its existence.
3. Therefore, the universe has a cause of its existence.
4. Therefore, if the universe has a cause of its existence then that cause is God.
5. Therefore, God exists.
I say “something like this” because there are a great many ways this argument is made.
Most modern philosophers allude to the Big Bang Theory when making this argument as “the beginning of the universe.” Unfortunately they make a whole slew of mistakes in doing so. This is what this post is about.
In capsule form, the “Big Bang Theory” (which was originally a pejorative label designed to cast scorn upon the theory) was formulated by an extrapolation. Up to the last 100 years or so we had no idea that the universe was expanding. Once we discovered it was, an enterprising scientist (who happened to also be a Catholic priest) said that if the expansion rate was consistent, then the universe would have begun its expansion 12-14 billion years ago. Since everything in the universe is moving away from every other thing (roughly), going back that far in time would have the stuff of the universe converging into a very, very small package.
In order to see all of the stuff flying apart as it is now, that beginning bit of stuff must have exploded, hence the Big Bang (actually a Really, Really Big Bang). Note Fourteen billion year extrapolations are rife with error. Consider how effectively we extrapolate weather pattern to predict the weather just a few days into the future.
Now, as you may well know, scientists cannot leave well enough alone and things have gotten a great deal more complicated, but that is the Big Bang Theory in a nutshell. And it did have scorn heaped upon it at its beginning, because just before it was proposed, most physicists thought that the universe was both eternal and static (not expanding). Finding out it was not static was mind boggling enough, but the consequence that the universe could not be eternal because of that was a bit too much for some to take. The nail in the coffin of a static, eternal universe was the discovery of the Cosmic Background Radiation, an actual artifact of the Big Bang, but let’s not get too far afield here.
The more ignorant sort claim that the Big Bang Theory has the universe being created from “nothing” but this is a mistake on their part. They also presume that the primordial universe (sometimes referred to as a “singularity”) was sitting in space when it went bang. According to the actual theory, all of matter and all of space-time are in that bit, so that bit is “the universe” and there is nothing else. This means no “empty space,” people, and no time outside of that bit.
So, these apologists, continuing to argue from ignorance, claim that their god provided the triggering event of the Big Bang, becoming the “cause” of the universe blowing up, in an obvious act of creation.
Again, this is bogus. This triggering is not the First Cause, as they claim their god to be. To trigger an event, there has to be something to trigger. So, what is the cause of the existence of the “singularity universe?” Why does it even exist? The correct answer, apologists, is “We don’t know,” not your god created it. You do not know that.
In “we don’t know” scenarios, one approach to advance is to hypothesize ways that the event could have occurred. One of these “educated guesses” might provide a clue as how to proceed closer to an answer. Here is an example of one such possibility. The “singularity universe” is inherently unstable and will always blow up once they are formed. (Why, we don’t know, but it is a possibility.) They will have to be unstable because there can be no triggering event to cause it to blow (there is no space, no time, outside of the singularity and change takes time, so any change has to come from within the tiny universe). Another singularity universe is created by the contraction of a universe as we see now. This is called the Big Crunch because all of the matter, time and space will necessarily get squeezed back into a much smaller space. I am not saying that this will happen, but that it might. If it did, then there are no “causes” of the universes that are created, they just happen. Of course, people can ask “what set this into being?” And, if this hypothesis were proven, I am sure that question will be asked. To which I answer, the universe is under no obligation to answer our questions.
Afterthought The Big Crunch Theory was originally dismissed for quite a long list of reasons (for one the universe’s expansion is accelerating and we would expect it to slow, stop, and then come back together for this scenario to work), but is currently being revived in a second go around.
An alternative to the BCT is the singularity universe is caused by a leak from another dimension (from the Multiverse, as it were). Another alternative . . .
My request of theists is that if you are going to play the God of the Gaps Card, make sure you actually know what the gaps are.
