What Came Before the Big Bang? Exploring Six Theoretical Possibilities

What came before the Big Bang? Did time start at that moment, or is our universe part of something even grander? In this deep dive, we explore six cutting-edge theories—Big Bounce, eternal inflation, cyclic universes, quantum fluctuations, and more—highlighting state-of-the-art research, limitations, and what it would take to prove them. If an alternative to the Big Bang is confirmed, it could reshape our understanding of time, space, and existence itself. Read on to explore the frontier of cosmology!
