Hypatia Stone Rattles Solar System

The micro-mineral analyses on the extraterrestrial Hypatia stone cast significant questions on a widely-held view about the primitive pre-solar dust cloud which our Sun, Earth and other planets were formed from.

Jan Kramers and Georgy Belyanin from the PPM Research Centre at the University of Johannesburg take us through the exotic nature of the minerals in Hypatia, and how the microdiamonds in a chip from the pebble ripped up a manmade polishing disk coated with industrial diamond within minutes.
