What happened before the Big Bang? Did time even exist? Was there another universe before ours? Or is the question itself impossible to answer?
In this video, we explore one of the greatest mysteries in science: what may have existed before the universe began. From the Big Bounce theory and eternal inflation to quantum fluctuations and the possibility that time itself started with the Big Bang, we'll look at the leading ideas scientists have proposed to explain the ultimate origin of reality.
The truth is that modern physics can describe the universe incredibly well after the Big Bang — but what happened before it remains one of the biggest unanswered questions in human history.
Watch until the end, because the most fascinating possibility might be the one nobody has imagined yet.
