To me, both the internal structure and the surface structure make it seem as it this is metal scrap from a pouring line. It has a sort of droplet shape, and inside you see rings. The "feathers" are where the metal cracked during the pouring.

Just a guess of course.

(2 lines lower, there is "the air force does not exist". I have seen lots of things that don't make any sense, but...)
