The Marvel Cinematic Universe has expanded its reach in recent years. Most notably, Doctor Strange explored the different dimensions and planes of existence that are out there. Ant-Man kicked it all off, though, as it introduced the Quantum Realm. Known as the Microverse in the comics, the Quantum Realm is the sub-atomic dimension that Scott Lang visits when he shrinks down to a dangerous level. It’s also where Janet Van Dyme, the original Wasp, is trapped. Given that, the dimension is thought to return in Ant-Man and the Wasp.

While we’re still waiting for confirmation on that, it’s now been revealed that the Quantum Realm will reappear in another upcoming MCU movie. Namely, Captain Marvel. The news comes from quantum physicist Dr. Spiros Michalakis, who’s worked with Marvel Studios in an advisory capacity. In an interview with Inverse, Michalakis hinted that the exploration of the Quantum Realm will be key to “a better understanding of Carol Danvers and her place in the MCU.”

“This is exciting for the future. There are different ways that some of these ideas appear on-screen in a few years. Not just for Ant-Man, but also for Captain Marvel and all of the Marvel Cinematic Universe.”

This is an intriguing reveal. In the comics, Carol Danvers AKA Captain Marvel has next to nothing to do with the Microverse. However, as we already know that the movie will significantly alter Carol’s origins story from the source material, it’s possible that Brie Larson’s version of the character will gain her powers due to a trip to the Microverse. That might seem very similar to the origins of the Fantastic Four, but seeing as Marvel’s First Family aren’t part of the MCU, that isn’t actually too much of a problem.

Captain Marvel is set to be directed by Anna Boden and Ryan Fleck and will arrive in cinemas on March 8th, 2019.
