Strange science story


Official prototype of kilogram mysteriously losing weight

[…] The 118-year-old cylinder that is the international prototype for the metric mass, kept tightly under lock and key outside Paris, is mysteriously losing weight — if ever so slightly. Physicist Richard Davis of the International Bureau of Weights and Measures in Sevres, southwest of Paris, says the reference kilo appears to have lost 50 micrograms compared with the average of dozens of copies.

“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.” […]

So what’s different in Paris? Why is that one getting lighter and the others aren’t?
