What is the Upside Down, and why is it frozen on 6 November 1983?Fiction
In-universe lore. Claims are judged against the fiction's own canon, not the real world.
For most of Stranger Things the Upside Down looked like a whole alternate dimension: a dark parallel Hawkins sitting right next to the real town. The final season replaced that reading with a narrower one, and this ledger separates what the episodes, the stage play and the creators actually establish about the place from what fans read into it and from what the show never answers.

The Upside Down turns out to be a bridge rather than another dimension: an interdimensional bridge that rips through spacetime, wildly unstable but held together by exotic matter found dead centre right above the lab. The wormhole connects Hawkins to another world, coined the Abyss.▰▰▰▱▱ likely3 points
Supports- Okay. So, this is Hawkins, and this is the Upside Down. We've always assumed the Upside Down was another dimension opened by Brenner, but it turns out it's actually a bridge. More specifically, an interdimensional bridge that rips through spacetime. It is wildly unstable, but held together by exotic matter, which we found dead center right above the lab.Dustin in Stranger Things Season 5, Episode 7 'Chapter Seven: The Bridge', transcript at Scraps from the Loft primary

A gate is an opening between dimensions, usually between the human world and the Upside Down. Gates have a thin filament that has to be broken to be passed through, and a gate disrupts the local electromagnetic field, causing nearby compasses to point toward it instead of the Earth's magnetic north. Eleven, Vecna and the Demogorgon all possessed the ability to create gates.▰▰▱▱▱ likely2 points

Back in Season 1 the makers were adamant that they did not want to explain the mythology in the show, liking that there was mystery and a lot that was not understood by the end of the season; Netflix said that was fine but that it would like to know. Time was then spent with the writers figuring out exactly what the Upside Down was and a 20-page mythology document was written, and at that point it was not called the Abyss but Dimension X, a Ninja Turtle reference.▰▰▱▱▱ likely2 points
Supports- That was all the way back in Season 1: Netflix just wanted us to explain the mythology to them, because we were very adamant early on, “We don’t want to explain it in the show. We like that there’s mystery, and that there’s a lot that you don’t understand by the end of the season.” They said, “That’s fine, but we would like to know.”Variety: 'Stranger Things 5' Volume 2 Spoiler Interview: Duffer Brothers Explain the Upside Down's Origins Word of God

Whether the Abyss and Dimension X are the same thing is not agreed. One account is that it was never officially Dimension X and that it is now always the Abyss; against that, Shawn Levy is reported to have said the answer is no to them being the same thing, and that he does not think the Abyss is Dimension X.▰▰▰▱▱ roughly even chance1 against2 points
Supports- Correct. Yes. I don’t think in the show we ever call it Dimension X - maybe that was in a script, and maybe we’ve referred to that in interviews. But it was never officially Dimension X. So that’s now always the Abyss, just to keep things as confusing as possible.Variety: 'Stranger Things 5' Volume 2 Spoiler Interview: Duffer Brothers Explain the Upside Down's Origins Word of God

Why this reflection of Hawkins is perpetually dark and blue-tinted instead of just being a frozen moment is never addressed, and no explanation is ever given for why a bridge between worlds would physically degrade and darken the matter it captures.▰▰▱▱▱ likely2 points

Why Eleven's contact in particular produced a permanent gate is left open: her banishment of Henry Creel to the Abyss in 1979 did not result in a permanent physical gate, the prolonged contact between Will and the Mind Flayer did not generate a secondary wormhole, and no reason is provided why subsequent psychic connections between humans and the Abyss did not produce similar dimensional rifts.▰▰▱▱▱ likely1 source
Supports- The series previously established that Eleven banished Henry Creel (Jamie Campbell Bower) to the Abyss years earlier in 1979, yet that interaction did not result in a permanent physical gate. Furthermore, the show fails to explain why the prolonged contact between Will (Noah Schnapp) and the Mind Flayer - another Abyss inhabitant - did not generate a secondary wormhole like the Upside Down. The narrative relies on the idea that Eleven is the only catalyst capable of such a feat, yet it provides no reason why subsequent psychic connections between humans and the Abyss did not produce similar dimensional rifts.Stranger Things: 5 Things That Still Make No Sense About the Upside Down - ComicBook.com analysis
