Is it possible to physically travel into fictional universes?

Not in the real world. It's just a concept from science fiction and imagination.

Well, traveling to fictional universes is pure imagination for now. But in some sci-fi stories, it might involve advanced technology like wormholes or interdimensional portals.

No, it's not possible in the literal sense. Fiction is a creation of the imagination, and while we can immerse ourselves deeply in a story through reading or watching, we can't actually step into that world physically. Our physical bodies are bound by the laws of the real world.

It's highly unlikely. The Bleach universe and the Naruto universe are separate entities with their own rules and boundaries. Fanfiction is a creation of the fans in our world, outside of the official storylines of both series. There are no mechanisms within either fictional world for 'bleach' to come across Naruto fanfiction. It's like two parallel lines that don't cross in the context of their in - universe existence.

In theory, it's possible. If we consider that there are magical libraries or places where different kinds of magical knowledge are stored. It's not a stretch to think that some magical being might collect all kinds of stories, including fanfic from other fictional worlds. So Harry Potter could potentially stumble upon Percy Jackson fanfic in such a place.

Well, there are countless fictional universes. It depends on how you define and categorize them. Some are well-known like the Marvel Universe and the Star Wars universe, but there are many more in various forms of media and literature.

It is indeed possible. Consider that the wizarding world is not completely isolated from the Muggle world. There are instances where wizards interact with Muggle things. Harry has Muggle - born friends like Hermione, who has a good understanding of Muggle literature. She could introduce Harry to Sherlock Holmes fanfiction. Also, there might be some magical means of accessing Muggle literature. Maybe there are spells that can retrieve or translate Muggle books. So within the framework of their fictional universes, Harry Potter can very well read Sherlock Holmes fanfiction.

In theory, it's not possible. Fictional worlds exist only in imagination and stories.

In theory, it's not entirely impossible. If we consider some sort of magical cross - over or a very creative fan theory, perhaps there could be a way for Harry to access this fanfiction. However, in the strict canons of their individual stories, it seems highly unlikely as they exist in different fictional realms with no established connection.

Fanfiction is all about bending the rules. Regarding Hermione being Clint's daughter, it could start with a plot device like a time - travel or dimension - hopping accident. Imagine Hermione gets lost in a different dimension where Clint is. He takes her in and raises her as his own. Her magical abilities could be a secret that she has to hide in this new world, which would add a lot of interesting plot twists and character development to the fanfiction.
