If The Big Bang Wasn’t The Beginning, What Came BEFORE It — And What Triggered EVERYTHING?

If The Big Bang Wasn’t The Beginning, What Came BEFORE It — And What Triggered EVERYTHING?

For many decades, what we were taught about the Big Bang often carried the shape of an “absolute beginning moment”: a singularity exploding out of “nothing” and creating the entire universe. However, that picture no longer accurately reflects how most contemporary theoretical physicists and cosmologists understand things today. The key point is not that the Big Bang is “completely wrong,” but that the Big Bang, in modern usage, is no longer treated as the start of all existence, but rather as the start of the hot, dense, observable phase of our universe. In other words, the central question is no longer “where did the universe come from in the Big Bang?”, but “what earlier stage produced the Big Bang, and by what mechanism?”

To understand why this viewpoint shifted, we need to look back at how the Big Bang model formed. At first, Newton imagined a static, eternal universe. Then Einstein’s general relativity showed that spacetime is dynamic and can expand or contract. Hubble later provided observational proof that the universe is expanding, which led to rolling the clock backward to a denser past state. After that, the discovery of the cosmic microwave background radiation (CMB) strongly reinforced that the universe once passed through a hot and dense phase—the empirical backbone of the Big Bang. But it’s important to emphasize: these lines of evidence confirm an early hot phase, not a forced conclusion that it was the “absolute beginning from nothing.”
