What Came Before the Big Bang? | Theories of the Universe’s Origin

What came before the Big Bang? 🌌

For thousands of years, humans have wondered where the universe came from. Ancient cultures spoke of gods, chaos, or eternal cycles of creation. Today, science gives us the Big Bang Theory — the idea that our universe began 13.8 billion years ago in a hot, dense state that has been expanding ever since.

But here’s the catch: the Big Bang doesn’t explain the true beginning. It describes what happened after — not what, if anything, came before.

In this video, we dive deep into the boldest ideas in modern cosmology:
✨ Eternal Inflation & the Multiverse – new universes constantly forming.
✨ The Bouncing Universe – endless cycles of expansion and collapse.
✨ Quantum Origins – Hawking’s no-boundary hypothesis and quantum fluctuations.
✨ Conformal Cyclic Cosmology – time looping across cosmic aeons.
✨ String Theory Models – universes born from higher-dimensional collisions.

We’ll also ask: is “before the Big Bang” even a meaningful question? Could time itself have begun at the Big Bang?

Whether you love astrophysics, philosophy, or just the mystery of existence, this journey will take you to the edge of science — and beyond.
