Last week we stepped out onto the back porch with the Bible skeptic Michael, and we looked up at the moon and the stars and the planets. From this common ground we asked ourselves this question; “Did the universe have a beginning, or has it always been here?” The answer of course, is the first step of a far-reaching journey attempting to answer the question; “Is God dead?” After asking this initial question last week, we summarized our thoughts by making the following claim: 1. Everything that begins to exist has a cause 2. The universe began to exist 3. Therefore, the universe had a cause We then concluded that the first claim is straightforward, and almost no one disagrees with it; everything that begins to exist does have a cause. But for the second claim; “The universe began to exist,” we said, sets at the heart of the argument because how a person answers this claim points either to a creator, or it points away from one. For these reasons, there is much to be said about the second claim here this week.
To claim that the universe began to exist is, essentially, to claim that it has not been here since eternity past. And that is exactly what Christian’s claim; that the universe began to exist the moment it was created by God. But how can it be that the Christian can make such a bold claim, especially without using the Genesis creation account? After all, remember the Bible skeptic Michael does not believe in the Bible. If we are going to stand on shared common ground with Michael, we are going to have to find some other way to defend the claim that the universe began to exist. How about mathematics? Math can certainly serve as common ground that both the Christian and the Michaels of the word can agree upon.
Speaking in mathematical terms, suppose I said that there is no such thing as an actual infinite set? Sounds a bit complicated but it really is not. In math class, remember, they taught us that a set of numbers looks like this (-2, -1, 0, 1, 2, 3). They call this a closed set because it is an actual set of numbers and it has a beginning, and an ending. Now if we think about an infinite set, we could write it; (. . . -3, -2, -1, 0, 1, 2, 3). This would be an infinite set going back to negative infinity. But it is not an actual infinite set because it goes on forever to the left. And, since it is not a closed actual set, we should not use the first bracket to “close” the set but it should read . . . -3, -2, -1, 0, 1, 2, 3). This is a potential infinite set, but not an actual infinite set. One could always add one more negative number on to the end of it.
Now suppose that the potential infinite set is a set of days instead of numbers, and suppose we said it was a set of days from eternity past to today. We could write it this way; . . . Oct 16, Oct 17, Oct 18, Oct 19). But here is the interesting part; If the universe has always existed, and if Michael and I stood on a timeline at Oct 19, and we began to walk backward through all the days going back into eternity past, we would never get to the beginning of the timeline. That is because if the universe has been here forever, then there are an infinite number of days past. But here is the amazing part; if Michael and I cannot walk an infinite timeline backward to a beginning, and if we were to turn around and begin to walk on that timeline from eternity past toward today, we can never get here because there would be an infinite number of days to walk across to get to today. The fact that we are here, all of us, today, means that somewhere in time past there was a first day. This is indisputable fact, and it seems to me Michael must agree. Time cannot go back for eternity any more than it can come forward from eternity to today; it had a beginning somewhere in history past. In classical philosophy they call it “the impossibility of an infinite temporal regress.” In Oklahoma we just say; “you can’t get there from here!”
But that is not all there is to know about the cosmos that can help us determine if the universe had a beginning. In fact, it turns out that in the early twentieth century, both Albert Einstein, and a man named Hubble suspected that something peculiar was happening in the universe that no one could see. Einstein suggested that based upon his mathematical equations related to his theory of General Relativity, the universe was indeed expanding. A few years later Hubble came to the same conclusion. What an incredible theory, that all the planets and the moons and the stars were moving further and further away from each other. But what does that mean? How does an expanding universe help us determine if the universe had a beginning? More importantly, what do Einstein and Hubble have to do with answering the question; “Is God dead?” Please join us again next week as we continue to stand on the back porch with the Bible skeptic Michael, and listen to What the Stars Say about whether or not God is dead.
Gloria in excelsis Deo!
