    Kinda sensationalist when we’ve known about cold welding for as long as the space program at least. Metals bond in a vacuum because there are no oxygen molecules to bond with their surface, when that surface is abraded. It makes for one of the bigger challenges in space, bearings that don’t seize up. Along with the even bigger challenge, an air tight bearing that doesn’t seize up, or leak.
