What Existed Before Time — And Is There a Before?

What existed before time began? This is the question that has kept thinkers awake since the ancient world — and modern cosmology finally has something real to say about it. In this deep-dive space documentary, we rewind nearly 14 billion years to the first instant of the universe and confront the strange possibility that the word "before" may lose all meaning at the edge of the beginning. You'll discover why the Big Bang was never an explosion in space, but the birth of space itself. We walk right up to the wall at the start of time — the point where our finest theories fall silent — and explore why the singularity is not an answer, but the sound of our equations breaking. You'll see how the oldest light in the universe, the cosmic microwave background, still passes through your body tonight, and how a faint radio hiss turned the beginning of the universe from philosophy into measurable fact. From the expanding cosmos and general relativity to cosmic inflation and the impossible smoothness of the infant universe, this is a journey through the real science of where everything came from. We ask whether time itself had a beginning, whether the universe is infinite, and what the boldest ideas in modern cosmology — a bounce, a no-boundary universe, an eternal foam — suggest about the origin of the universe. If you love slow, thoughtful documentaries about deep space, the beginning of time, and the biggest questions in physics, subscribe and follow the journey. Because the mystery of where the universe came from, and whether anything existed before time, may be the one question every human being has always shared. 00:00 — The Question That Kept Him Awake 03:30 — Why the Universe Is Flying Apart 07:15 — The Big Bang Was Not an Explosion 11:40 — The Wall at the Start of Time 16:20 — When "Nothing" Turns Out Not to Be Empty 21:00 — The Oldest Light in the Universe 26:10 — The Impossible Smoothness 31:30 — Is There Really a "Before"? 36:00 — You Are Made of the Beginning #space #cosmology #universe MORE Universe & Cosmos Documentaries: 👇 How Did the Universe Begin    • How Did the Universe Begin — And What Happ...   How Did Something Come From Absolutely Nothing?    • How Did Something Come From Absolutely Not...   What Is Dark Matter — And Why Does It Control the Universe?    • What Is Dark Matter — And Is It the Univer...   What Is Time — And Is It Actually Real?    • What Is Time — And Is It Actually Real?   What Is the Edge of the Universe — And What Lies Beyond It?    • What Is the Edge of the Universe — And Wha...
