Mass less

So, the official metal lump that signifies the mass of one kilogram appears to be shedding mass: it is 50 micrograms lighter than the average of several copies. Either it has gotten lighter, or the copies have, on average, gotten heavier.

What could cause this? My first thought is radioactivity, but I would assume the physicists in charge would think of this too (the article doesn’t say).

But then, discussing it with Logan, we came up with better ideas:

1) A ghost inhabited the sample, and has now left. It is well known that ghosts have a mass of 0.00005 kilos.

2) Greys. Not sure how they did it, but aliens are crafty.

3) NASA faked the kilogram.

4) Hoagland is in charge of the mass, and the hyperdimensional physics dictated the — oh, screw it.

You know the deal: pretend this is a pareidolia post, and make up your own reason. Best one wins nothing. Good day sir!

    Well, as we all know, quantum mechanics predicts that the state of sub atomic particles are in a state of flux which may, or may not exist at any moment. At the moment of the weighing the quantum mass of 0.000005 kg was “phased out”. Notice how some of the copies of this standard mass were slightly heavier. In those cases the the quantum mass has “Phased in”.

    This scientific proof of “effects at a distance” is precisely the kind of effect that science and “big pharm” have been trying to hide from you. Well they can hide no more. I personally use this effect to detoxify the blood and promote healing. By combining quantum healing with essential oils and aroma therapy my institute can promote the healing life force within us all to counter such devastating maladies as:

    cancer
    bloating
    toenail fungus
    itchy mosquito bites
    leprosy
    and that vague feeling that you may have forgotten to bring something important when you go on vacation.

    Here at the institute (I’ve always wanted to say that) you may use these methods while enjoying a relaxing stay in one of our holistic and fung shui designed personal bungalows. Our trained staff can also administer hot volcanic mud baths (for removing toxins), cucumber facials (for removing toxins) and homeopathic therapies (which actually apply extremely tiny amounts of toxins, but not so much that you’d notice).

    The native Americans have known about the secret of the quantum cube weight loss plan for decades, and now that secret can be shared with you.

    Please visit our web site to make a reservation at the institute and to view our fee schedule.

    My guesses:

    1) God wanted it to weigh less
    2) The Tardis got too close to it, and affected its gravitational wobbly-bits
    3) The micro-black hole from the Bermuda Triangle shifted to the area where the kilo is stored, and sucked up some of its mass
    4) It was replaced by The Doctor, Doc Brown or somebody from the Enterprise with an almost exact duplicate, but they forgot to wipe off their fingerprint when they measured its weight, making it one fingerprint lighter when they cleaned it just before putting it back.

    You keep using that word, “heavy.” Is there something wrong with the earth’s gravitational pull?

    Basically, the explanation is that in AD 325 the First Council of Nicaea excised the real Ten Commandments from the Bible in the name of making consistent doctrine. While the traditional interpretation of the Second Commandment goes along the lines of “Thou Shalt Not Set Up False Idols”, the real version actually states “Thou Shalt Not Set Up Artifacts As Definitions Of Physical Units”. Thus science is reaping the rewards of its Sin in the eyes of the Lord Thy God.

    Other than radioactive decay, my best guess is that the gravitational pull under that area has lessened slightly. Perhaps a large solid mass that used to rest under France broke away with the magma under the mantle. Gravity does vary very slightly depending on where you are in the world, and your altitude, of course. Perhaps that area raised up a few inches over the last century. It isn’t like they’ve ever measured the mass outside of that one building.

    Isn’t this all moot though? I thought they recently changed the standard to make the kilogram equal to a specific number of atoms of a specific element recently.

    Their government is covertly adding and removing small amounts in order to help import/export/sales ratios. After all, cash isn’t counted by weight, but goods is. When it’s beneficial for a kilo to be slightly less, they remove some, otherwise they add some. Currently, weight-based exports is higher (by cash value) then weight-based imports, so consequently it’s in the “decreased” state. This may be a lot of the reason the dollar is worth so little vs European currencies these days – the constant shortchanging of everything imported. Granted, it doesn’t seem like a lot of decrease, but when you multiply it by the vast quantities of exports I’d say it’s.. well.. lots.

    Think about it, what other earthly reason could they have for not specifying a kg in a physical constant (x electron weights, x atom specific Si isotope, whatnot)? To control how much a kg is, that’s why and why only! Too bad for them they flubbed up and didn’t adjust all reference copies equally this time around – Muahhhahaha.

    The loss is proportional to the amount of people who would of cared if FOX had left uncensored Sally Field’s comments on the Emmy’s last night.

It isn’t like they’ve ever measured the mass outside of that one building.

    Except the article explicitly states:

    It is kept in a triple-locked safe at a chateau and rarely sees the light of day — mostly for comparison with other cylinders shipped in periodically from around the world.

    So how can it be an external effect if it is measured side-by-side with the other masses?

    This does raise an interesting question about the comparison methods. The article states that the measured inconsistency is between this article and the average of the copies. How are they measuring the copies? In fact, how are they measuring this article? Couldn’t the problem be in the instrumentation, not the article?

    > Isn’t this all moot though? I thought they recently changed the standard to make the kilogram equal to a specific number of atoms of a specific element recently.

    From
    http://www.bipm.org/en/scientific/mass/prototype.html

    The kilogram is the last remaining base unit of the SI that is still defined by a material artefact.

    The international prototype is kept with its six official copies in a vault at the BIPM.

    The international prototype was manufactured in the 1880s of an alloy of 90 % platinum-10 % iridium. Four of the six official copies date from the same period.

    Assuming the prototype has actually lost mass, is it possible for some of the metal to simply sublimate directly off the surface, forming a thin metal vapor? Or is the entire thing kept in a sealed container, so the lost particles would still be trapped in its containing vessel?

    As I understand it, the standards are stored in air, and are cleaned (including rubbing!) before weighing for calibration purposes. Since they are stored at different locations, I assume different persons do the cleaning, and slightly different storage conditions are present. I would look into the cleaning procedure first. As I understand it, the weight of the contaminants that are removed during cleaning is much more than the observed loss.

    Radioactive decay is one explanation; but some of the standards were made from the same material at the same time and then separated. Makes it unlikely to affect only one.

    When they measured it there was less air sitting on top of it.

    It was once stolen and the serial numbers filed off.

    Since it’s the original, it was never labeled at all – while the copies were all marked “copy” and added weight.

    Lost weight to be in better playing shape for Boston. Oops, sorry, wrong KG.

    Original was handled carefully when measured, copies had fingerprints on them.

    We all seem to be forgetting that a kilogram is defined as the mass of the kilogram prototype. The prototype cannot lose 50 micrograms because it is always exactly one kilogram. Therefore, the rest of the Universe has gained mass.

    Too many electrons in upspin, therefore lightening the kilogram. On the other side of the universe is a kilogram with too many electrons in downspin, causing it to be heavier.

    Pons and Fleischman had reunited and conducted an “asymmetric annihilation” experiment. For the best calibration, they decided to use the one and only reference kilogram in Sevres, France. Asymmetric annihilation does not need antimatter, the regular matter just annihilates itself. Unfortunately, the 1250 kw-hrs generated did not justify the fifty metric tons of coal necessary to facilitate the annihilation.

    Possible aiding the above, that the platinum was extremely slightly impure and the other non-platinum part got selectively removed.

    This is old news, but sadly I can’t find any good links about it (only a few things from the wayback machine in Danish), but a Danish kook by the name of Arne Gabs (millionaire from a photo developing lab) used this as ‘proof’ for the his ‘theory’ about gravitation.

    Something about gravity-particles which the Earth absorbs from the sun causing it to swell. Eventually the earth would become a star yadda yadda yadda.

    I can’t be arsed to find something more substantial now. Suffice it to say, you can never beat the real thing (craziness, I mean).

    Alternative theory that overturns the established scientific theories about big bang, with the theory of relativity and quantum mechanics, as well as offers a new explanation for gravity and describes a new force: repulsion”

    Damn. I feel stoopeeder for translating that. Notice how 65 libraries have chosen to shelve it (I tried reading it … fifteen years or so ago, that’s how I know of this).

    Gabs was rather ‘famous’ for ‘predicting’ long term weather (the papers trotted him out with stories about how the Summer was gonna turn out) as well as days when ‘catastrophes’ would happen: planes falling, earthquakes, &c &c.

    A 5×10^-8 change in mass? A one ton mass at 1m from the bar would give about 7×10^-9 change in weight, so maybe a change in the water table….

    Ooops! I’m sorry, my brain tried to actually think there.

    Of course, the probability of random mutations in the bar evolving it into a new size is so remote that, obviously, this is the result of Intelligent Design. I mean, really- how fast does the DNA in iron mutate? NOT FAST ENOUGH.

    Interesting… I was thinking as well it could possibly be a change in gravity in the area, due to the structures or where it is being measured. That would not be much… but this is only a tiny change in mass.

    Perhaps past attempts were less accurate than thought? Or maybe some of the surface has somehow been ablated?

    I’d like to see the actual distribution of the mass for all the kilogram standards, so the prototype is 50 micrograms less than the average of the remainder. Was one of them disproportionately heavy, skewing the average? Perhaps someone surreptitiously handled that one and left a few dozen finger prints.

    The information that the standard is lighter than the average isn’t meaningful without knowing if it is lighter now than for previous comparisons or if the copies are heavier.

    Of course you would hope the folks involved in the standards institute thought of these questions and ruled them out already.

    The answer is quite simple, when you look at it. Lump of metal, like water, have memory. They can remember when they first got out of home, when momy blew up in nova, they can remember when they settle down with others to form a new star, those were good times but also bad because he was rejected and had to content to join a planet forming and not even a big one.

    But things were not as bad, because soon his planet would become the envy of the family, after all he and his rejected friends started a bio-chemical experiment called life and soon they became the most beautiful planet of the entire system. Oh those are the best memories. :-)

    But then, humans, a kind of ape of some sort, started to junk the place up and cut all those green trees. But the worst part was being captured and manipulated by those terrible humans. They get you, melt you and filter out all of your essence as to make you pure and bland, and they lock you up in a sterile place that forbids you to gain new particles and regain content.

    So you’re lost and alone, devoid of all that constituted you for such a long time. You keep only your memories, you hold to them as hard as you can, but soon they start to fade out. If only you’re so luck as the other lumps that at least got to travel places…

    So you see, the problem is that the poor lump of metal is suffering from amnesia. It is loosing it’s memory.

    As this was reported in the mainstream media, and is science-related, it is therefore wrong. (Rupert Murdoch must have futures invested in the pound.)

    The reference masses are compared to the master via an electro-mechanical balance method, IIRC. My guess would be that the comparison procedures have been “improved” in some way, and thus inadvertently borked. You would assume that they also checked the reference masses against one another to verify that there was a definite deviation, but I have learnt the assumption lesson…

    A few years back, it was noted that Indonesia’s master kg was losing mass compared to the Australian and New Zealand masters. Investigation determined that there was a diligent curator who would carefully polish the mass up prior to each comparison – thus removing a little mass each time.

    Obviously, God speaks English and uses the Imperial system of measurement, and has been slowly converting the world to use both. We can expect the kg to lose another 546,407,629 µg over time so the standard weight is, once again, the pound.

    The Slug standard was stolen years ago. They have secretly been defining the slug in terms of the pound in terms of the kilogram for over a century. Shhhh, don’t tell anyone.*

    * There never was a slug standard. The official U.S. customary unit of mass is the avoirdupois pound. Somewhere or another physicists got it in their heads that weight was force, and thus made the pound a force unit. Then they had to define a mass unit, they named the “slug” (when not using “pounds-mass” and “pounds-force”). The Avoirdupois pound was originally defined in terms of the troy pound standard. As of the Mendenhall Order in 1893, all U.S. Customary units are defined in terms of S.I. units.

    I suppose it cant be the fabled proton decay, as the above poster said, it would mean that protons decay only in platinum iridium bars used in weight(mass) prototypes, and never decay in thousands of tons of water observed by tons of instruments. :)

    Change of local gravity field is IMHO as plausible as above, aka non likely.

    Some small fraction of metals were natural isotopes, or have been turned into isotopes and have decayed. Though that would have released quite a bit energy over the years, and it would have been noticed. I mean, if it is radioactive decay, about 20 millionth parts of the bars mass have been converted to energy trough decay…

    So, this one is also Alien Space Bats.

    Two solutions i can think off that might be most plausible:
    a) it evaporated,
    b) they cleaned it off…

    Greg B: “0.000005 kg” = 5 mg; you need two more zeros to get to 50 ug.
    Blake Stacey: yes, it is; you’re right.

    0.05 kg = 50 g
    0.00005 kg = 50 mg
    0.00000005 kg = 50 ug

    Actually, it’s quite simple. The power company originally misread the meter 1250 kW-hr too high. They’ve since discovered their error, and adjusted the reading down by this amount. So not to worry — the 50 mcg will be restored as soon as they get the discrepant energy back and convert it back into Pt-Ir.

    I still like the global-warming-phlogiston explanation. But if I win the nothing, I promise to be humble. And to donate it to Al Gore to buy no jet fuel. Say, which judges do I bribe with a little nothing in order to win the big nothing?
