Ah, no, you're right, it does go back to Crisis on Infinite Earths, but that Allen had gone back in time and given his younger version his powers was not revealed until two years later, in Secret Origins Annual #2. This was retconned in Rebirth. Hat tip to you, I did not know that. :)

Crisis? As in Crisis on Infinite Earths (I know for a fact that is not so), or Infinite Crisis or Final Crisis, which are in the noughties. Besides, I thought it was in Rebirth.

If it's Geoff Johns, then I'd think so, yes. Besides, that is not a very old explanation. Also, it was Barry AND Wally.

Funnily enough, and since this is Geoff John we are talking about, you might find that the lightning might actually *not* have been from the accelerator, or indeed any freak weather phenomenon.

Well, yes, obviously. :) But I was rather hoping they'd upgrade a bit y'know. Like how they replaced "weird chemicals" with a "particle accelerator". Very little is scientifically accurate in comics—this ain't hard science fiction. But, some, at least. A teeny tiny bit. A smidgen. Pleeaaase.

I don't even…I give up. :(

(6) A crucial fact about Jay Garrick is that he *does not* get his powers from the Speed Force, unlike almost every other speedster out there. So the reason he's lost his powers could be because…ahem…maybe the hard/heavy water thing just doesn't work in a different universe. {aaggh I hate comic book science…or…

Centripetal force needs something to be rotating or spinning. What is spinning here, apart from my head? :D

His Black Flash face and costume even more so. :D

Er, what?

I got disheartened. I mean, it's the comics, and most comic book writers don't give a damn. They're too busy with the plot and characterization, and rightly so. But a tiny smidgen of scientific accuracy wouldn't derail the train. :(

Ok. Points.
