Regarding Le Grande K, the actual scales used to measure the Platinum specimen is not kept in the same vault. Until we can identify the mechanics involved in this "expansion" of space and/or matter, we will not be able to isolate or reproduce the result.
One particular identifying evidence (other than K) of this "mechanism", are the ocean floors. No geologist can refute the age of the crust, however in doing so, by default, they have to dismiss the "this for that" equilibrium of subduction versus spreading. The subduction/Benioff zones simply do not have enough crustal consumption to match the new crust.
This can be seen in blue on this map, and the particular shapes and forms can also be seen on our satellite moon and other celestial bodies. Noting for clarity, other celestial bodies and moon have not been dated. Merely, they just appear similar, and I am going off that same assumption. But something fishy is going on.
