so they found Copernicus, or his body, and they've double checked it against some spare Copernicus hairs they had sitting around. they took his skull, and they recreated his face from it, and voila! you now know that he was a really ugly dude.
i would be so pissed if i die, and then say however many thousand years later someone recreates my face and they make me look that bad.
Polish tests 'confirm Copernicus'
