If you were to travel to another universe where your counterpart was born 30 years later than your own birthdate, it would mean that the timeline and events in that universe progressed differently compared to your own. Here's a hypothetical scenario to help illustrate the situation:
Let's say you were born on January 1, 1990, in your original universe. If you traveled to another universe where your counterpart was born 30 years later, your counterpart in that universe would be born on January 1, 2020. This means that in that universe, events that occurred during the 30-year period between your birth and your counterpart's birth would have unfolded differently.
The implications of this time difference would be significant. Your counterpart in the alternate universe would have grown up in a different era, potentially experiencing different historical events, technological advancements, cultural shifts, and societal norms compared to your own universe. They would have had different opportunities, experiences, and influences throughout their life.
It's important to note that when discussing traveling to alternate universes or parallel timelines, we enter the realm of speculative fiction and imagination since such technology or phenomenon has not been scientifically proven or achieved. The concept of parallel universes or alternate timelines remains theoretical and is commonly explored in science fiction literature, movies, and TV shows.
