It's reasonable to expect that most plausible hypotheses are wrong, because most of them are. Of course you test the ones that look hopeful, because that's the only way to find out which ones have more explanatory power than what you currently have.

That trailer showed me its heart was in the right place with the short bit where Kara tries and rejects a skimpy spandex costume. On closer examination, it consisted entirely of items Supergirl actually wore in the comics:

And if that happens, a) we'll have some cool new physics (or at least evidence pointing to a hypothesis other than the standard model, which is sorely needed), and b) we'll then be able to say that current particle accelerators can produce quantum black holes.

Though once we start getting into alternate timelines, I can imagine a course of events in which we call pocket computer/camera/game console/book viewer/navigator/video recorder/telegraph/organizer/television/music player devices (that oh, can also make voice calls) "pagers" being as likely as our calling them…

Unfortunately, yeah. (Who's running the undead pool for Uncle Ben?)

Or the many DC characters (Black Canary, Zatara, Red Tornado…) who moved from Earth-2 to Earth-1 in the Infinite Earths era.

The only thing we really know is that he has the brighter red costume and the white circle around the lightning bolt. That previously signified the older Flash who saved Barry and fought Thawne, who presumably had a living mom and started his career in 2020.

From your linked article: "The LHC has already been trying to detect mini black holes, but has come up empty-handed. This is what would be expected if there are only four dimensions, since the energy required to produce black holes in four dimensions would be much larger (10^19 GeV) than the energy that can be…

"He predates the Comics Code! I'm out of here."

I'm hoping audiences can manage not to be more confused than they were by the fact that Kevin Costner's Robin Hood didn't reference the Errol Flynn or Sean Connery versions. Paranoia about confusion and diluting the brand is what got us the Bat-embargo on JLU (along with various other distortions, like having to…

If TimeWarner were trying to coordinate things, it would almost certainly be the movies calling the shots, not the TV shows. Is there anyone who thinks that would be an improvement? Thank Grodd for balkanization, says I.

"Why on Earth would I know that? Do you know who won the 1909 World Series off the top of your head? I had a computer for that stuff."

Seconded. Refining out the gold from the source material and discarding the dross is the key to this sort of adaptation. Obviously there's always disagreement on which is which, but hopefully that can be left in the dross pile.

One of the nice bits in Mark Waid's "The Return of Barry Allen", where Wally West faces (SPOILERs from here on out)

Though she was dead for six years in the comics, and only brought back to give Barry some closure in the very last issue of his series, literally the month before he died in Crisis #8. She was then absent from the comics for another nine years. That's at least medium-serious for a comics death.

They're operating on a theory that the changed past overwrites the future, rather than one in which branching timelines continue to exist. Whether they're right about that is unclear.

Clearly TV needs to develop a counterpart to the asterisked editorial footnote box: "Why did original Barry warn off our Flash? Find out in the 'Flashpoint' miniseries, loyal reader!"

Cue TV adaptation of the introductory panels showing that on Earth-2, some people are basically identical to their Earth-1 counterparts except older (picture of Supermen or Wonder Women), some are very different (picture of Flashes or Green Lanterns), and some have no counterparts at all (picture of Doctor Fate and…

That makes a lot of sense. Especially since the original "Flash of Two Worlds" began with Barry doing an "Indian rope trick"— climbing up a rope and disappearing into what turned out to be Earth-2. Running up a building into an overhead wormhole is arguably a scaled-up, more spectacular version of the same thing.

I think Barry's being sufficiently in tune with himself to understand is well within the bounds of plausibility.
