Alien Alloys On Earth?
“I don’t think there’s any alloy we can’t recognise,” says Richard Sachleben, a retired chemist and member of the American Chemical Society’s council of experts. Alien Alloys On Earth?? That’s simply not doable.”
Alloy, according to Sachleben, is a blend of multiple constituent metals. On Earth, everything is normal. Alloys include brass and steel. In truth, the planet’s natural-occurring gold is made up of elemental gold mixed with other metals like copper or silver.
Databases exist in all metal phases, including alloys, according to May Nyman of Oregon State University’s Department of Chemistry. These databases include simple methods for identifying metal alloys. So, if there’s an odd alloy, figuring out what material it’s made of isn’t difficult. The X-ray diffraction technique is used to study crystalline alloys, which are made up of a mixture of atoms that form an ordered structure, according to Nyman.
“How has the hunk of metal changed?” Nyman wondered. “As a scientist, that’s the kind of question I’d be asking.” Maybe some study can take you to where the metal was mined, or what nation employs that specific alloy, or something like that, if it has to do with world politics and we want to know where the metal originates from.”
The wavelength of an X-ray is about the same size as the spacing between atoms. It means that the X-rays diffract when they approach the well-ordered material. Then you may find out the distance between the atoms, how well-ordered they are, and what the atoms are. It also allows you to figure out how the atoms are arranged.
Nyman also mentioned that if the vehicle is from space, ionisation and spacefaring debris could leave metal telltale indications. Both Sachleben and Nyman agreed that an alloy chunk that had never been seen before could have fallen from the earth’s outer space; it wouldn’t necessarily be debris from an alien craft.
According to Sachleben, alloys impact the ground on a regular basis. Alloys that travel through space, such as those found in common nickel-iron meteorites, leave obvious marks.
