Jef Ongena lecture on Georgens Lemaître

Jef Ongena's lecture on Georges Lemaître sheds a clear light on the origins of the Big Bang theory. He explains how the Belgian priest and astronomer was the first to realize that the universe is not static, but constantly expanding from a primeval atom. In doing so, Ongena corrects the historical narrative in which Edwin Hubble often receives all the credit for this discovery. During his presentation, he clarifies how Lemaître kept science and faith strictly separate to protect the integrity of both fields. The speaker further connects these historical insights with modern astronomical observations of cosmic background radiation. The result is a compelling account of intellectual courage and the Belgian contribution to our fundamental knowledge of the cosmos. Thanks to Ongena's accessible style, this complex subject becomes understandable for a broad audience. This ensures that Lemaître's legacy remains alive in contemporary scientific discussions about the beginning of everything.
