India, April 6 -- Perhaps the most significant thing quantum mechanics has contributed to popular culture is the multiverse theory.
This idea can be traced to Hugh Everett III's Many-Worlds Interpretation of quantum mechanics, which he proposed in 1957.
To put it in terms of Schrodinger's cat, when the box is opened, there is one universe in which the cat is dead, and another in which the cat is alive.
The real-world rider to this is that this is only possible on quantum - that is, infinitesimal - scale.
Yet almost every fictional multiverse, from the Marvel Cinematic Universe to Terry Pratchett's Discworld, draws on the multiverse concept first put forth by Everett.
How else has quantum mechanics permeated popular culture?
