JK. Interesting stuff.

wouldn’t that be a hydrogen atom?
To: All
Yeah, but it still can’t make the Kessel run in 12 parsecs.

Crossing a liberal is even faster.

I thought the shortest time in the universe was the interval between the light turning green and the taxi behind you honking its horn.

Two atoms make up the H2 molecule.

You pretty much never find single hydrogen atoms. The binding energy is so much lower in the diatomic state that atomic hydrogen would rip more out of water molecules if it found any.

heh good one- another one is- the shortest time is right after a woman says to do something, and the husband opens his mouth to object, it’s that infinitesimally small span of time when her brow begins to wrinkle, her foot starts to tap, and her finger begins to pointing-

Is that a longer or shorter period than the length of time between Biden’s lies?

The time between Justice Barrett’s confirmation and swearing in was pretty short.

Seems to me you run into some issues with Planck’s constant there, in determining the position of the electrons to such high certainty.
Heisenberg is pissed off, certainly.

heh good one- another one is- the shortest time is right after a woman says to do something, and the husband opens his mouth to object, its that infinitesimally small span of time when her brow begins to wrinkle, her foot starts to tap, and her finger begins to pointing- That is VERY close to the observed time span between asking a woman what's wrong and when she snaps back, very shortly,
"NOTHING."

What I learned after reading the article and thinking about the topic:
60 years ago Id hear, in response to a time inquiry, something like quarter to freckle . Not until tonight did it occur to me the joke had to do with looking at a watch-less wrist.
Perhaps when I heard the joke it was stale enough to no longer require acting out. Now I get it, ha!
Wonder what they meant by half-past the monkeys...
