The title is a little silly. It’s from outside our solar system, but there’s zero evidence suggesting it’s technological or made by aliens. It’s just a meteor that was going really fast, and it was made of something that was sturdy enough not to break up too much.
I would think that, if other people agree with his analysis and this does seem extra-solar, and we have a reasonable guess as to where it might have landed, a couple million would be a small price to check out an extra-solar object.
