Spider-Man: Far From Home - Everything You Need To Know About Marvel's Multiverse

4. There's A Difference Between Alternate 'Worlds' And 'Dimensions'

In the wake of Far From Home's multiverse tease, there were a few bemused commenters online who didn't seem to get the fuss. 2016's Doctor Strange - at least according to them - had already introduced the concept, but they're committing an easy mistake.

Scott Derrickson's supernatural flick may feature lots of trippy, inventive visuals, but it doesn't actually showcase the multiverse. It actually highlights several different pocket dimensions, realities that exist within our own, such as the Dark Dimension, meaning there's a delineation to be made between 'dimension' and 'reality', even if Nick Fury interchanges the term in in the trailer for Far From Home.

According to the Official Handbook of the Marvel Universe, a 'dimension' is a "universe or realm containing space, time, matter and energy". Asgard and the Nine Realms are all technically dimensions, while Strange deals with alternate dimensions such as Dormammu's all the time in the comics.

So, going forward, we can expect to see alternate dimensions and alternate universes. The important thing to remember, though, is that each alternate universe will invariably contain alternate dimensions too. Granted it can get confusing, but they're a distinction to be made.
