Iron in Bronze Age weapons came from outer space: Study
A France-based study has claimed that most of the iron used in weaponry dating to the Bronze Age is of meteoric origin. By studying the ratios of iron, cobalt, and nickel within the artefacts, researcher Albert Jambon differentiated between smelted iron and iron of extraterrestrial origin. The finding could explain how ancestors used iron without access to smelting, said Jambon.
