Is the parallel universe is real?
You must have come around the concept of multiverse also known as parallel universe once in your life. Here I'm going to explain it to you in a very simple language. Hope you will like it.
What is the parallel universe?
A parallel universe, also known as a parallel dimension, alternate universe, or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own. (Source) This is a frictional definition. Quantum physics also suggest that there is a possibility of a parallel universe. It is also known as the multiverse.
Here I'm trying to make it as simple as possible.
Is the multiverse theory is true?
Well, Studying about multiverse means observing the multiple universes from some other frame of reference which doesn't lie in any universe. Means a completely different dimension. Which is literary impossible at the present time!
What proves do we have for a multiverse?
According to quantum mechanics. We can't say a cat is alive or not inside a box unless and until we open it. It means, there are two possibilities in this case. Same applies to all of our life events. In some case, you skip this post, in other you read it completely and in another, you also comment and share this multiverse post. The possibility is infinite. And hence for each possibility, there must be a different universe. (Source)
Whatever the source be. It is frictional. And a lot of awesome movies and TV series are based on this theory.
This is by no means a complete list, but a sampling of some of the more-quoted examples.
Marvel Comics and DC Comics feature stories set in parallel universes that are part of the multiverse.
Many anime series, such as "Digimon," "Dragon Ball" and "Sonic the Hedgehog" feature alternate versions of their characters from other universes.
Parallel universes appear in games such as "Dungeons & Dragons," "BioShock Infinite," the "Final Fantasy" franchise, "Half-Life," "League of Legends," "Mortal Kombat" and "The Legend of Zelda."
"Flatland: A Romance of Many Dimensions" (1884), by Edwin A. Abbott, is a story about a two-dimensional world that includes living geometric figures such as circles, triangles and squares. The novel also includes other universes such as Lineland, Spaceland and Portland. This book was adapted into a feature film in 2007.
"Men Like Gods" (1923), and H.G. Wells novel, included a "para time" machine and explored the multiverse.
"The Chronicles of Narnia" (1950-56), a C.S. Lewis book series, features several children who move between our world and the world of Narnia, where there are talking animals. Some of these books were released as feature films earlier in the 2000s.
An episode of "Star Trek" featured a "mirror universe" in which the characters were more ruthless and warlike. The concept was repeated in nearly every subsequent "Star Trek" series. In 2009, the "Star Trek" universe got a reboot in a movie that put the characters from the 1960s original series in an alternate universe. The movie starred Chris Pine and Zachary Quinto and set off a series of other "Star Trek" films.
In "The Dark Tower," a Stephen King series that began in 1982, travellers go through portals to different levels of the titular tower (in other words, parallel Earths). Part of the series was adapted into a feature film in 2017.
The "Back to the Future" movie series (which began in 1985) follows the adventures of the McFly family, including visits to 1885, 1955 and 2015. The second film, in particular, shows the drawbacks of an alternate reality when one character uses it to get rich by nefarious means. The series starred Michael J. Fox.
In the "His Dark Materials" series by Philip Pullman, children move between multiple worlds. The first book, "The Golden Compass," was adapted into a film in 2007.
"Sliding Doors" (1998) is a film that showed two parallel universes depending on whether the main character caught a train or not. It starred Gwyneth Paltrow and John Hannah.
"Run Lola Run" (1998) is a film starring Franka Potente. The film shows multiple alternatives as a woman tries to get 100,000 Deutsche marks in only 20 minutes to save her boyfriend's life.
"Timeline" (1999) by Michael Crichton follows historians who go back in time to the Middle Ages. (While the book is mostly a time travel book, the multiverse is used in it as well.) A film based on the book was released in 2003.
"Donnie Darko" (2001) is a film in which a high school student finds himself confronted with visions and tries to figure out their meaning. It starred Jake Gyllenhaal.
"The Long Earth" book series, by Terry Pratchett and Stephen Baxter, discusses parallel universes that may be nearly the same as Earth.
"Stranger Things" (2016 to 2019) is a science fiction-horror television series that begins with the investigation of a young boy's disappearance in a small town. The series includes a discussion of an alternate dimension called the Upside Down.
"Dr Strange" a marvel move, it has a concept of multi-dimension. Like mirror dimension.
"Rick and Morty" a television cartoon series, where a genius grandfather able to develop a portal machine which can travel in the multiverse and different dimensions.
Is there any scientific prove about multiverse or a parallel universe?
The answer is a big No! All these are just theories. And the reason why we don't have any proof about the multiverse is I have already explained. We don't have such technology by which we can observe multiple universes. We are limited to our resources.
