Difficult to get what was not said in the comment I'm replying to. So fine, I don't know my dating techniques. Uranium radiological dating sounds fine. Why not that? >> if it turned out to come from the future > I don't even… have a sense of humor? It is certainly possible if we had a extra-terrestrial organic matter (which we don't) that it could test as coming from the future based on carbon ratios, though obviously it would not actually be from the future - thus "on that scale". I'm not sure if the same applies to Uranium radiological dating.
