A multiverse is many universes all existing at the same time. It's like having a big library with an infinite number of books, and each book represents a different universe.
Imagine you're watching a movie that seems so real, but what if it was just one small part of a much bigger story? What if there were other movies, similar to this one, playing out in their own ways, all at the same time? That's kind of like the idea behind the multiverse. It suggests that every possibility exists somewhere else, creating an endless variety of worlds and scenarios. When scientists talk about the multiverse, they often wonder if it's true or not - but the concept has become more popular in science fiction movies and TV shows too.
The world, considered as lacking in purpose, design, or predictability.
