Hypertime and the Pre-Crisis multiverse[]
I noticed that there are some similarities to the creation of the 52 multiverse and the Pre-Crisis multiverse: Brilliant scientist uses powerful device which results in the creation of a multiverse.
Yes, there are many differences but it would explain how Alexander Luthor, Jr. and Brainiac could "create" or "access" realities that didn't exist anymore; they were in fact accessing hypertime and the Pre-Crisis multiverse was a hypertime fragmentation (ala Infinite Crisis) of one Earth.--BruceGrubb (talk) 11:33, October 18, 2017 (UTC)
Hypertime "realities"[]
I noticed in the note section a list of "Hypertime realities." As I understand, Hypertime is "the overarching and interconnected web of timelines and realities."
That said...I don't think it was supposed to refer to a limited number of realities, but rather all of them. In other words, any universe in which time travel is possible should be a hypertime reality in the technical since.
This is how I understand it. As BruceGrubb said above, in Hypertime, you can even access realities that "no longer exist," from the perspective of the time traveler. We saw Superman of Earth-Two in The Kingdom. We know that Earth-Two merged with Earth-One to create a new timeline during Crisis on Infinite Earths, but that's a different timeline, with hypertime, you can travel to timelines like that. Or "recreate" them, as BruceGrubb said.
I liken it to traveling sideways through time. Most of the time when a time traveler travels through time, it's either forward or backward, unless they do something that changes history, which causes them to branch off into a new timeline. An alternate timeline, if you will. This is not the same as a parallel universe. So many get those two concepts confused.
It's actually the same universe, but it's history was altered, making it seem like a new world. That's not to say that it couldn't be a parallel universe, since hypertime is webbed into all realities, but that's not usually what happens. It did with Flashpoint clearly.
Anyway, I think the main thing wrong with this article is a lack of explanation about Hypertime from the in-universe perspective. We all know what it is from a real world perspective. Mark Waid wanted to use the multiverse again...clearly...but the in-universe story is more what I'm interested in, and some of this seems to be contradictory, even within the article itself.
