The God Theorem

Can a mathematical theorem point to the existence of God?

Consider whether our universe had a beginning, as claimed by the Bible. Until about a hundred years ago, there was no scientific evidence it did. Then, in the 1920s, Edwin Hubble discovered the universe is expanding in a way that implies a beginning, or “Big Bang.” Stunning confirmation of this theory came with the accidental discovery in 1965 of radiation, “relic photons” from the Big Bang (actually, to 380,000 years after the Big Bang, when the universe had cooled down enough to allow light to travel freely). Today the Big Bang theory is commonly accepted.

By itself, the Big Bang theory claims the universe had a beginning, and suggests the existence of God. So today most Atheists have retreated to belief in a “multiverse.” They believe our universe is an insignificant part of a much larger scheme, a collection of universes typically called the multiverse. To avoid the need for a beginning, Atheists typically believe the multiverse contains an infinite number of universes. One popular theory has universes exploding out of other universes, in “eternal inflation.”

Which bring us to the Borde-Guth-Vilenkin theorem, what I call the God theorem. (For videos on this theorem, click here.) In 2003 these scientists proved that, if you assume an expanding universe, you can’t have an infinite past. Every universe that expands must have a space-time boundary in the past. What’s so powerful about this theorem is that it covers all cosmological models and theories of expanding universes. According to Professor Vilenkin:

All the evidence we have says that the universe had a beginning.

With the proof now in place, cosmologists can no longer hide behind the possibility of a past-eternal universe.

The multiverse has other problems, not the least of which is that it’s impossible to prove or disprove, and therefore many people think should not be considered “science.” The multiverse theory may be losing favor, even among Atheists. An opinion piece in the current issue of New Scientist magazine, by physicist Lee Smolin, is titled: “You think there’s a multiverse? Get real.”

Here’s how one blog sums it up:

If the universe came into being out of nothing, which seems to be the case from science, then the universe has a cause. Things do not pop into being, uncaused, out of nothing. The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.

Sounds like God to me. Thanks for reading.
