Speculating about the events in a parallel universe during the periods of the Mahabharata and Ramayana is purely a matter of imagination and not based on any concrete evidence or scientific understanding. However, if we consider the concept of a parallel universe where different possibilities and variations exist, we can explore some hypothetical scenarios.
In one parallel universe, the events of the Mahabharata and Ramayana might have unfolded similarly to the way they are depicted in the Indian epics. The epic battles, conflicts, and the triumph of good over evil could have occurred in a parallel universe just as they are described in our world's legends.
However, in another parallel universe, the stories could have taken entirely different paths. The characters may have made different choices or faced altered circumstances, leading to alternative outcomes. Perhaps the wars never took place, or the heroes and villains had contrasting roles. The narratives could have diverged in various ways, offering an entirely distinct perspective on those ancient times.
Ultimately, the concept of parallel universes is speculative and belongs to the realm of science fiction and imagination. While it's fascinating to ponder the possibilities, there is currently no scientific evidence supporting the existence of parallel universes or the specific events that might occur within them.
