Why It's IMPOSSIBLE for Time to Have a Beginning | Brian Greene

Did time actually begin with the Big Bang — or is that just a limitation of our models? In this video, we explore the deepest questions in cosmology about the origin of time itself. With insights often discussed by Brian Greene, we analyze what physics says about time, causality, and whether a true “beginning” can even exist. Explore the mysteries of the universe with Brian Greene Explained. From quantum physics and spacetime to black holes and the multiverse, this channel brings complex ideas into fascinating long-form science content.
