english: These shifts could be tiny— for instance, certain constants we’ve measured  with accuracies of parts per million have stayed steady for decades, so any drift would have to be  on an even smaller scale.
non_english: Ove promene bi mogle da budu sićušne - recimo, neke konstante koje smo izmerili sa preciznošću do milionitih delova su decenijama nepromenljive, što znači da bi svaka promena morala da bude još manjeg opsega.
