How to write parallel universes in fiction?

Parallel universes in science fiction are frequently depicted as existing alongside our own, yet separated by some sort of barrier, whether it's a dimensional rift or some other mysterious mechanism. They are often used as a plot device to explore 'what - if' scenarios. For instance, in many superhero comics, there are parallel universes where the heroes have different powers or personalities. This allows writers to tell new and interesting stories that deviate from the established canon of the main universe. It also gives a chance to explore different social and cultural concepts by presenting alternate versions of Earth or other planets.

Often, they are depicted as alternate realities with different versions of characters or events. For example, in 'Sliders', each parallel universe has distinct cultures, technologies, and sometimes even different physical laws.

Typically, parallel universes in fiction are shown as places with distinct characteristics. Some may be utopias or dystopias compared to our world. They might have different technological levels. Like in 'The Dark Tower' series by Stephen King, there are different worlds with their own rules and threats, and the concept of parallel universes is crucial to the story's structure and plot development.

In the 'His Dark Materials' trilogy by Philip Pullman, there are multiple parallel universes. One notable is Lyra's world, which has daemons - physical manifestations of a person's soul. There are also other worlds with different climates, cultures, and forms of life, all connected by the mysterious Dust.

In fantasy, the Dark Tower universe by Stephen King is a unique parallel world. It has a blend of different elements including Western, horror, and fantasy. Then there's Wonderland from 'Alice in Wonderland'. It's a topsy - turvy world with strange characters like the Cheshire Cat and the Mad Hatter. Also, the Neverland in J.M. Barrie's 'Peter Pan' is a parallel universe of sorts, a place where children never grow up and there are pirates, fairies, and mermaids.

One well - known example is in the 'Marvel Cinematic Universe'. The concept of the multiverse was introduced, where different parallel universes exist with various versions of superheroes. For example, we saw different versions of Spider - Man from different universes in 'Spider - Man: Into the Spider - Verse'.

Well, for the characters, it's a huge shock. The existence of parallel universes makes them question everything they know. Their sense of self is challenged because they might meet versions of themselves with different values or memories. They start to wonder if their own reality is even real or just one of countless possibilities. It can also create a feeling of insignificance as they see how vast the multiverse is and how small their own world seems in comparison.

The creation of parallel space science fiction could consider the following aspects: 1. Exploring the concept and principles of parallel space. You could write a story about parallel spaces, describing their physical and historical differences and how they interact. 2. Description of the protagonist's adventures in a parallel universe. The protagonist could be set in a parallel universe and discover that this universe was different from his past. He began to explore this new universe and interact with the local residents. 3. Set a villain as a threat in this universe. You could give the villain a reason, such as wanting to destroy the protagonist's laboratory or control the life in this universe. 4. Exploring the culture and values of the parallel universe. You can set up a parallel universe with different cultures and values. The protagonist can discover these differences during the adventure and try to understand them. Set a fascinating ending for the protagonist to find the answer in this new universe and return to his original universe. He could add some suspense to the ending to make the reader want to continue reading. I hope these thoughts will be helpful. I wish you success in your novel writing!

Some people might dislike parallel universes in fiction because they find the concept confusing or it messes with the traditional story structure. Also, it could make the plot overly complex and hard to follow.
