Kilo prototype mysteriously loses weight

My science teacher in Junior High in the late 60’s always corrected us saying,”A pound is weight! A gram is mass!”...........

Didn't Steven Wright once say that somebody stole all of his furniture ... and replaced it with exact duplicates?

[Verginius Rufus]

Yes, a man who used to weigh 100 kg would now weigh, say, 102. So he goes to the doctor and doctor warns him to watch what he eats—he’s just put on two kilos.

Maybe the gravitational field strength changed.

a meter being based upon one wavelength of a certain frequency of light

The speed of light was defined in 1983 as exactly 299 792 458 meter/s. A meter is how far light travels in 1/299 792 458th of a second.

The platinum-iridium cylinder has been the standard for over 100 years, I believe. The mass of water at 4 C is too hard to do reliably.

A second is is the time it takes for 9 192 631 770 oscilations of a specific wavelength of light emitted by the cesium-133 atom.

The kilogram is defined to be approximately the weight of a liter of water, but in actuality, it’s the weight of that cylinder.

Proposals have been made to change it to something more concrete (I remember my chem teacher describing a kilo as a mole worth of an element) but the actual decision to do so hasn’t happened yet and is currently scheduled for a time 3-4 years from now.

How about minute shifts in gravity?

[VOA]

"The mystery is that they were all made of the same material,
and many were made at the same time and kept under the same conditions,
and yet the masses among them are slowly drifting apart," he said.
"We don't really have a good hypothesis for it."

Everbody (and everything?) ages differently?

[hadit2here]

If it's the reference, how do they know that it has lost weight/mass if it is the reference against which they are measuring it. Doesn't some sort of self-recursion enter into play here at some point?

change in gravity...

The damn French have lost control of the kilo. Better let Poland or the Czech Republic have it for a while, so they can fatten ‘er up.
Dumplings, you know....

[SunkenCiv]

Wow, due to my having to switch to my old machine and needing a different monitor, I've been running at 640x480, and this ping logo looks *huge*.

Some pretty colors and large letters, looks like a periodic chart, but to say what it actually is I cannot ‘cause the darn print is so small on my screen. Meany!

It’s the Atkins Diet! Feed that thing some carbs, man!

It was observed that samples hung above a thermoionic current exhibit a weight decrease
directly proportional to the intensity of the current. The observed phenomenon appears to be
absolutely new and unprecedented in the literature and can not be understood in the
framework of the general relativity. It is pointed out the possibility that this unexpected effect
is connected with a possible correlation between gravity and electromagnetism.

Gravity is not behaving as theory suggests it should behave:

According to our current ‘understanding’ of gravity, over the last 34 years both Pioneer 10 and 11 should have traveled more that 400,000 kilometers further than they have actually flown.
