Cepheid Variables

And what might those be? As described in this article from the Smithsonian Magazine, they are pulsating stars in far away galaxies used to measure distances and speeds of travel. Apparently astronomers are concerned that their investigations seem to show that the universe is expanding at a speed even faster than was previously believed. 

So what? Who, except for a few cloistered academics, can possibly care about the movement of celestial bodies millions of light years away. Knowing their exact speed and direction has zero to do with anything happening or likely to happen here on earth, even if they could actually prove their measurements. Let's find out where the body of super Thoroughbred race horse Shergar ended up. Not that it's wrong to seek out answers to esoteric questions. It's just that public funding shouldn't be used to finance it. That's a role for people like Bill Gates or Juan Soto.
