Has the universe always existed, or did it have a beginning? And if it began to exist, what caused it?

In this video, we explore the Kalam Cosmological Argument for the existence of God. The Kalam philosophical argument has its roots in medieval Islamic theology, and was popularised in recent years by philosopher William Lane Craig.

The Kalam argument begins with a simple claim: whatever begins to exist has a cause. But can we prove that the universe actually began to exist? And if it did, does that necessarily point towards God?

In this episode, we discuss:

• Whether science and the Big Bang theory point towards a beginning of the universe
• The difference between potential and actual infinity
• Why an infinite past might be impossible
• Hilbert's Hotel and the paradoxes of infinity
• Why Thomas Aquinas disagreed that reason alone could prove the universe had a beginning
• Whether a multiverse or cyclic universe could explain our existence
• Why the Kalam argument points towards a cause beyond the physical universe
