10 Best High Sci-Fi Universes In Fiction

The Marvel Universe grounds itself in reality by allowing us to see Earth as we know it in a different light, but it also goes one step beyond that by reaching out to the stars, exploring broad mythologies and introducing the vast multiverse, which makes it literally able to explore any avenue it wants. Thanks to this, it's hard not to see it as one of the most significant sci-fi properties in fiction.

This multiverse of superheroes has everything you need as every inch of the property is covered with exciting characters, some of whom have even become integral pieces of popular culture. It would also be remiss not to mention the Marvel Cinematic Universe, which has completely changed the way movies work and has turned into an unstoppable juggernaut of box office dominance.

Besides the obvious success, Marvel explores science fiction differently, as it covers all facets of the genre. The subjects range from robotics to space travel to time travel to even wars between alternate realities. Sure, the superheroes are the main focus, and they are not what you'd consider traditional sci-fi, but other heroes like The Guardians of the Galaxy step up in that regard, and The Avengers themselves are no strangers to space.
