But look at all the great things you can say from this article, such as ‘vacuum density waves’ or ‘VLBI baseline lengths’. No math required.
WTF is a “vacuum density wave.” As far as I know, vacuums contain no matter (or energy or whatever there is a vacuum of) in the first place, so the concept of a “vacuum density” becomes meaningless by definition. I think I would have to use doublethink in order to accept such a thing.
