knowledge, including pseudoscience, stuff that scientists are indoctrinated with

Rigid, inflexible, dogma driven thinking of "mainstream" scientists who scoff at the obvious reality of alien visitation and irrationally make demands for Hard Evidence and refuse to investigate claims for which no evidence exists.

To a scientist diamond is interesting for its range of exceptional and extreme properties. When compared to almost any other material, diamond almost always comes out on top. As well as being the hardest known material, it is also the least compressible, the stiffest material, the best thermal conductor with an extremely low thermal expansion, chemically inert to most acids and alkalis, transparent from the deep UV through the visible to the far infrared, and is one of the few materials known with a negative electron affinity.
