Dunn measured 0.1 inch per revolution on the above sample! Nothing they had could do that. More evidence of high technology.
Once again, you have to prove it before I have to explain it, as BMK pointed out, and I still don't believe that a normal explanation has been conclusively ruled out.
Do you have a reading comprehension problem? It would explain a lot.
I very carefully Pointed out that it is clearly not vitrified. Do you even know what that word means? It means glassified. De-crystalized. If the core was vitrified, it would be covered with an opaque amorphous layer of something like obsidian. The crystal structure of the rock underneath, which at that size would take weeks or months if not years to form, would not be visible. It is vanishingly unlikely that any layer would be transparent. This is something to note about the blocks of Peru. All of this so-called "vitrification" appears to be the same color as regular andesite, except in a few spots that are obviously blackened. I would be interested to know if it would be possible to observe the surface mineral structure of the rock with a hand lens.
