I thought we had a pretty good grasp on things like that many decades ago.As an astronomer, I can say that the distance measurements from the Hipparchos satellite were significantly different from many thousands of others calculated by other, pretty solid, methods. My guess is that there was something fundamentally flawed with Hipparchos, exactly what, I have no idea, but it could be alot of things.It wouldn't be the first time the European Space Agency put a piece of crap into orbit (the ISO observatory satellite was a good example of a billion dollar satellite that was a complete piece of junk. I wasted months trying to make even a tiny bit of sense from the data. It should have produced 30,000 publications, it produced less than a tenth of that).I think all this article is saying is that the Hipparchos measurements of distances to stars are garbage.
