00:00Every story has a beginning. Every journey starts somewhere.

00:03But what about the grandest story of all? The story of the universe itself?

00:08We are told that the universe was born from a singular event, the Big Bang.

00:13A moment of unimaginable energy, an explosion from a single point,

00:18giving rise to time, space, and everything we know.

00:22But a question lingers, haunting scientists and philosophers alike.

00:26What was before the Big Bang? Was there nothing?

00:30Or was there something that existed before time itself?

00:33Could it be that our universe is just one of many?

00:36Or is the very question itself meaningless?

00:40Let's dive deep into this cosmic mystery, exploring scientific theories,

00:45philosophical paradoxes, and mind-bending possibilities

00:48that challenge the very limits of human understanding.

00:52The problem of before. Can time exist without a beginning?

00:56To ask what was before the Big Bang assumes that there was a before.

01:02But here's the problem. Time, as we understand it, began with the Big Bang.

01:07The equations of physics break down when we rewind the universe back to its very first moment.

01:12Imagine a novel. You can flip through the pages, moving forward or backward through the story.

01:19But what happens before the first page?

01:21There is no before the first page because the story simply begins there.

01:25Could the universe work the same way?

01:27Physicist Stephen Hawking once suggested that asking what was before the Big Bang

01:33is like asking, what's north of the North Pole?

01:37The question itself may not make sense because time itself didn't exist yet.

01:42But is that truly the final answer?

01:45Or could there have been something before, hidden beyond the reach of our understanding?

01:49The eternal universe.

01:52Was there something before?

01:54Some scientists argue that the Big Bang was not the absolute beginning,

01:58but rather a transition.

02:00A transformation of an older state of reality into what we now see as our universe.

02:061. The cyclic universe.

02:09A never-ending story.

02:11What if the universe is like a beating heart,

02:15expanding, collapsing, and then rebirthing in an endless cycle?

02:20The idea of a cyclic universe suggests that our universe was born from the collapse of a previous one,

02:26just as one wave in the ocean follows another.

02:29In this model, there was no true beginning.

02:32Instead, the universe has always existed in some form,

02:36going through cycles of creation and destruction.

02:38This would mean that before the Big Bang, there was another universe,

02:43one that lived, expanded, aged, and then collapsed into itself,

02:47triggering the birth of our own.

02:49Could it be that we are merely one chapter in an infinite book of universes,

02:54each written and rewritten over eons?

02:572. The quantum foam.

02:59A sea of possibilities.

03:02Another theory suggests that before the Big Bang,

03:05there was a strange and chaotic realm known as quantum foam.

03:08This is a world where space and time flicker in and out of existence,

03:12where tiny energy fluctuations constantly create and destroy miniature universes.

03:18Think of it like boiling water, where bubbles constantly form and disappear.

03:23Perhaps our universe was just one of those bubbles,

03:26one that, against all odds, expanded into the vast cosmos we see today.

03:31If this is true, then before the Big Bang, there was never truly nothing.

03:37Instead, there was an infinite sea of potential universes,

03:40with ours being just one of countless possibilities.

03:44The multiverse, are we just one of many?

03:46What if our universe is not unique?

03:50Some theories suggest that our universe is just one of an endless number of parallel realities,

03:55each with different laws of physics, different histories,

03:58and perhaps even different versions of ourselves.

04:021. The Bubble Multiverse.

04:06Imagine each universe as a bubble floating in an infinite cosmic ocean.

04:11New bubbles form constantly,

04:13each representing a new universe with its own Big Bang.

04:16If this theory is correct, then before our Big Bang,

04:19there were countless others, each birthing a universe of its own.

04:23This would mean that our universe was never alone.

04:25It was simply one bubble in a vast, eternal sea of creation.

04:312. The String Theory Hypothesis.

04:35String theory, one of the most ambitious ideas in physics,

04:39suggests that the universe might be shaped by extra dimensions beyond the three we experience.

04:44Some versions of string theory propose that our universe was created

04:48when two higher-dimensional brains collided, triggering the Big Bang.

04:53If this is true, then before our universe,

04:55there was a vast, invisible cosmos of higher dimensions,

04:59operating under completely different laws of physics.

05:02Our Big Bang was just the result of a cosmic event far beyond our comprehension.

05:07The mystery of nothing.

05:09Can nothing exist?

05:11But what if before the Big Bang,

05:13there was truly nothing?

05:15No time.

05:15No space.

05:16No matter.

05:18Just absolute emptiness.

05:20Can something emerge from nothing?

05:22This question is at the heart of one of the greatest debates in philosophy and science.

05:27Some physicists believe that even nothing is unstable.

05:31In a state of true nothingness, quantum fluctuations could still occur,

05:35sparking the birth of the universe in a sudden, spontaneous event.

05:40Others argue that the concept of nothing itself is an illusion,

05:44that there has always been something,

05:46even if it was beyond our ability to perceive it.

05:49A universe without an answer?

05:50So what was before the Big Bang?

05:54Perhaps the truth is that we will never fully know.

05:57Maybe our understanding of time, space, and reality itself

06:01is too limited to grasp the full picture.

06:03But that is the beauty of the question.

06:06It forces us to think beyond what we know,

06:08to push the boundaries of science and philosophy.

06:12It reminds us that even in an age of incredible knowledge,

06:15there are still mysteries that remain beyond our reach.

06:18And perhaps one day, as our understanding of the cosmos deepens,

06:23we will finally uncover the truth.

06:26Until then, the question remains open.

06:29A riddle written in the very fabric of existence.

06:32What do you think?

06:33Was there something before the Big Bang?

06:35Or is it a mystery we will never solve?
