The concept you're referring to is known as the "Many Worlds Interpretation" (MWI) of quantum mechanics. According to MWI, every quantum event, including every choice made, results in the creation of multiple parallel universes, branching out to accommodate all possible outcomes.
In this interpretation, if we extend the idea to the macroscopic level, there could be universes with different initial conditions, physical laws, or events that never occurred in our own universe. It's theoretically possible that there could be a universe where the Big Bang never happened or where different fundamental events unfolded.
However, it's important to note that the Many Worlds Interpretation is just one of several interpretations of quantum mechanics, and it remains a topic of debate and exploration among physicists and philosophers. While it provides a mathematical framework for understanding quantum mechanics, the existence and characteristics of these parallel universes are still hypothetical and lack empirical evidence.
Furthermore, it's worth noting that the concept of the Big Bang is closely tied to our current understanding of the origin and evolution of the universe. If the Big Bang did not occur, it would have far-reaching implications for the fundamental structure of space, time, and cosmology. Speculating about universes with different fundamental events or conditions is intriguing, but ultimately it remains a subject of theoretical exploration rather than empirical confirmation.
