Another intriguing concept revolves around the notion of a multiverse, wherein our universe exists as one of countless bubbles in an expansive sea of universes governed by differing physical laws. Central to this idea is the concept of eternal inflation, which posits that inflation—an exceedingly rapid expansion of space—occurred shortly after the Big Bang and continues indefinitely in parts of the universe beyond our perception.
From this perspective, our universe could be likened to a bubble formed from a much larger, ever-expanding primordial cosmos. Each 'bubble' universe could potentially have originated from quantum fluctuations that propelled its growth, analogous to molecules forming in a vast ocean.
