The Marvel Cinematic Universe is full of mysteries, and one of its darkest and most intriguing settings is the Dark Dimension, seen in Doctor Strange, and a theory makes it an even more horrifying place. As the MCU has expanded, it has taken its characters and the audience to places far from Earth – from planets like Xandar to realms like Asgard and dimensions like the Quantum Realm – and if that wasn’t enough, it’s now exploring other universes thanks to the multiverse, which has added even more mysteries to the MCU’s bag.
