The concept of the multiverse originates from theoretical physics and cosmology. It suggests the existence of multiple universes or parallel realities that may coexist alongside our own universe. Each of these universes could have its own set of physical laws, constants, and conditions, potentially leading to different outcomes and possibilities.
In the context of the Marvel Cinematic Universe (MCU), the multiverse has been introduced as a storytelling device. It allows for the exploration of alternate realities, versions of characters, and different timelines within the Marvel universe. It provides a narrative framework to introduce new and diverse storylines, as well as to connect different Marvel properties across various mediums, such as movies, TV shows, and comics.
The concept of the multiverse in the MCU was explicitly introduced in the film "Doctor Strange" and further expanded upon in the Disney+ series "Loki" and the film "Spider-Man: No Way Home." It has opened the door for characters from different realities to interact, for different versions of characters to exist, and for events in one reality to impact others.
The multiverse in the MCU allows for creative storytelling opportunities, introducing variations of characters and exploring different narrative possibilities. It adds depth and complexity to the Marvel universe and enables the exploration of diverse storylines, alternate timelines, and the potential for crossover events.
It is worth noting that the portrayal of the multiverse in the MCU is a fictional interpretation for entertainment purposes and does not reflect any scientific consensus on the existence or nature of a real multiverse.
