Although there are no ifs in history, If parallel universes actually exist, then the history of the universe we live in would be unfolding differently in other parallel universes. It is possible that events we believe to be true in our universe could be unfolding differently in other parallel universes, leading to different outcomes. However, we can imagine the existence of these unseen parallel universes. This concept allows us to explore the possibility of different realities and helps us to better understand the mysteries of the universe.
