Where the mind truly starts to boggle is remembering that a zeptosecond still falls incredibly short of the Planck time/distance at 5×10−44.
It's certainly exciting to speculate how much closer to an actual Planck /measurement/ we may yet achieve.
t_P being the Planck time here.
Planck time is really small.
If we had clocks with this level of accuracy, you could measure the weight of someone walking in the room because of their time dilation.
Yet another way of saying how amazing this new result is: A second is much "closer" to the age of the universe than it is to a zeptosecond.
.0000000000000000093889s = 9389 zeptoseconds, and this clock can measure time in mere hundreds of zeptoseconds.
It works because it assumes swapping the cable has no effect on the delay. But the same cannot be said for your hypothetical atomic clock - creating an electronic switch with matched delay is an obvious challenge, but then, even minor physical movement of the cable will change its delay.
If you think about it, this is true for any time measurement. If you only had one clock, how would you know if it was properly calibrated?
There was no clocks and detectors involved that you might think of at first.
A carrier signal is generated (as high as 10^27)  - modulated by some observable - and then recorded and analyzed. The highest resolution event that will be visible in the waveform will be 1/(2f) where f is the frequency of the carrier signal. The 1/2 factor is due to the sampling theorem .
You’d imagine that a CMS for a university website would support formatting of something as simple as an exponent. Instead what you get is a claim that a zeptosecond is somewhere between 10 and 21 seconds.
(tho tbh it looks a bit janky -- but better than "10-21"!)
“Of course it should communicate detailed chemical bonds and protein folding!”
College: "They definitely learned this in highschool"
The only formatting I got was whatever I could do with HTML and CSS back in 2008. There was a sort of rich text editor you could also use, but it was really hard to make it do what you wanted.
Question: does this not violate the "quantum" in quantum physics? I thought that a quantum particle had to be in either one state or another simultaneously in all places in the universe, because otherwise, it would have a gradient between one and the other, and its energy would no longer be quantised.
When you go into smaller length and timescales, these quantization effects kind of lose or change their meaning.
So an electron doesn't instantaneously change between "shells" in an atom upon reception of a photon if you look closely enough, there are indeed smooth intermediary states and maybe the researchers are saying they detected subtleties in these states (I didn't read the original research article yet).
Congratulations to all involved!
Or 250 Billion zeptoseconds == 0.25 nanoseconds (aka: typical 4GHz desktop CPU these days). Many CPU operations can be applied to a register in a singular clock tick (Add, Sub, XOR, AND), multiplication can happen once-per-clock tick but still has a latency of a few cycles (maybe 4 to 5 clocks, or ~1-nanosecond)
Wow. Seriously impressive work.
In what situations would one use this measurement?
24-7? Say no more.
But if you were a betting man, you would bet on this being false, seeing as 70% of studies cannot be reproduced.
And this is a study that no one else can even hope to reproduce. Its just a claim.
And there is the comedy 'gag' of 24-7. Ie, the time they measured was all the the time. Hilarious.
Even though the odds are on my side. According to science!
> “Since we knew the spatial orientation of the hydrogen molecule, we used the interference of the two electron waves to precisely calculate when the photon reached the first and when it reached the second hydrogen atom,"
On the other side, we're all very used to mega- and giga- and tera-, and for data center folks, peta- as well, and we'll adapt to the higher-order prefixes as they enter more common use.
And we're not asking the layman to know all these, either. Zepto- will never be in common use; that's for particle physicists and basically nobody else, so far at least.
Everyone already knows 10^12=tera, so we're covered there.
I think the number of people who could (correctly!) name even half of those is much smaller than you think.
the text divides time as 'murta' and 'amurta'...the first translates to 'embodied' and the latter translates to 'unembodied'. it means 'unreal time'. in unreal time, there is no destruction. all 'murta' time units are based upon 'one respiration' or 'one prana'. (living time or 'murta' unit)
one truta is 1/37500 of a second. i dont know if it goes smaller than that..but it builds up from that to a kalpa of brahma which is 4.32 billion human solar years. two kalpas make a day for brahma. 30 days make a month of brahma and he lives for 100 years. currently, we are in the 50th year of brahma, first month and in kali yuga(4 yugas of which kali is the last make one chatur yuga..1000 chatur yugas make one kalpa.)...kali yuga started ...acc to these texts started in 3102 BCE and will end after a run 432,000 years. current kali yuga began roughly 5,121 years ago and has 426,879 years remaining as of 2020 CE.
i wasnt paying attention to the quantum scale and was fascinated by the cosmological time. at some point, i expect to return to the lunisolar calender time that was really the original purpose of my reading, but i got carried away and went down the rabbit hole.
its going to be difficult to get back to astrology study because turns out there are multiverses and multiple brahmas who 'bubble' in the ocean and disappear as they create and destroy their worlds and themselves. and then there is time dilations for various creatures each one perceiving time on a different scale. this with the accompanying mythology is better than any sci fi i have ever read.
