Faith and the Expanding Universe of Georges Lemaître

On October 29th of last year, the International Astronomical Union (IAU) voted to recommend renaming Hubble’s Law the “Hubble-Lemaître Law.” That such a vote would take place today—during a time when science and faith are portrayed in the media as implacable foes—speaks to the remarkable character of Lemaître himself, the Belgian monsignor and astronomer who made a number of fundamental contributions to the science of cosmic structure and origins. His dual career as priest and scientist puzzled many in science and in the public at large when he was alive, and his struggles to defend his “Big Bang” model of the origin of the universe against those who accused him of being religiously motivated epitomizes the growing tension between science and organized religion in post-war Europe and the US. The story we will tell about Lemaître will of necessity be selective in the details of his life, which was complex and rich enough to merit multiple biographies,[1] [2] as well as numerous articles. I want to emphasize those aspects of his career that merited the …

Attempts to Explain Cosmogony Scientifically

In Modern Physics and Ancient Faith, I discussed some of the speculative scenarios in which time has no beginning and the Big Bang is merely the beginning of one part of the universe or one epoch in its history. Another line of physics speculation accepts the idea that time has a beginning, either the Big Bang that occurred some 15 billion years ago, or some earlier perhaps even bigger Bang, but seeks to give that beginning a scientific explanation. Many scientists are under the impression that such an explanation would render a divine creator superfluous. As I will explain later, this notion is based on a misunderstanding of the idea of Creation. However, let us put that issue aside for now and focus on the scientific ideas. The Reasons to Look for a Theory of the Beginning Theories of the beginning of the universe generally are formulated within the field called “quantum cosmology.” There are several motivations for this work. At the most basic level, scientists seek to understand phenomena, and the Big Bang is a phenomenon. …
