247 zeptoseconds = 494 half-zeptoseconds

JK. Interesting stuff.

H₂ size 120 picometers 12 x 10^-10 m

wouldn’t that be a hydrogen atom?

[LegendHasIt]

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.

[Jonty30]

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

[grey_whiskers]

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.

What I learned after reading the article and thinking about the topic:

60 years ago I’d 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 monkey’s...

I still believe time is a human construct, whether a short or longer time according to the above theory with photons and atoms interacting. It shows a difference, but it is still the human mind that constructs it. And yes, I did stay at a Holiday Inn.

Gosh.
It seems like only yesterday we were contemplating why the chicken crossed the road.

[Dagnabitt]

Still longer than Joe Biden’s attention span.

[P.O.E.]

I always thought the second was a little too long. Maybe they should rethink the whole thing and go to metric time after all. Make the second about 1/3 shorter, then make 100 seconds replace the minute.

Daylight Savings Time they could just move the decimal point.

C’mon man, who didn’t know this!

[tired&retired]

Not to be confused with a Yoctosecond.

Zep-to-dee-doo-dah, zep-to-dee-ay.
My, oh, my, what a wonderful day.

This is exactly how long it takes for Schumer to step in front of a camera or Pelosi to eat a pint of ice cream.

This distance is the speed of light going about 74 picometers, just over half the above-stated size of the hydrogen atom, 120 picometers. (247 10^-21 s x 3 10^8 m/s = 74.1 10^-12 m)

The time it takes for Helium 5 to decay to Helium 4 is shorter: 10^-20 seconds. About the time it takes for light to cross the nucleus, which is much smaller than a molecule.
