Kilogram reference losing weight.

PARIS (AP) — A kilogram just isn't what it used to be. 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."

it cud mean that the force of gravity acting on that place is lowering down, maybe due to less activity in the core of the earth. hey im a genius yayyy

this was in the news long time back ... and that is actually due to the sphere being made of different elements and there is a group of scientists who are co-ordinating amongst themselves and hav almost completed the making of new spheres which are made entirely of 1 element so they will not degrade ....

parts of the sphere were done in some country and then another and last i read the spheres were being shipped to australia as there is a company who is famous for making spheres which are absolutely spherical

say what?

kya hua

jo tu bola samaj me nahin aaya

the original spheres were made of different metals and elements .... now being a mix over the years those metals have started to deteriorate now scientists are working on spheres which are made of a single metal so they wont deteriorate and current status of those spheres is that after being measured to accuracy and blah blah they have been sent to australia where a company will make them into spheres ...
