Does parallel universe really exist?

When we talk about the possibility of multiple universes, we are referring to the idea that there could be many separate and distinct “realities” or “worlds” coexisting alongside our own. These universes may have different physical laws, properties, and dimensions, and could exist in parallel to our own universe. So basically, there’s this idea that there could be lots of different universes happening at the same time, and there are couple of evidences that make people think it might be true.
There are several evidences for parallel universe, such as Hawking radiation, which says that anything going into a black hole might end up in another universe. or the gravity waves act oddly and deviate objects from their orbits, possibly due to the influence of parallel universes.
This idea of multiple universes has been proposed in various fields of science, including physics, astronomy, and even psychology. For example, Stephen Hawking was the leading theoretical physicist who advocated multiverse theory. I believe it remains a highly theoretical concept till today, and it is an area of active research and exploration, as scientists continue to investigate the possibility of parallel universes and their potential implications for our understanding of the universe and our place in it.
