Because they screw it up and spew misinformed drivel like Salon does. If they would have done a modicum of research, they would have found out the discovery is the sign of a gravitational wave embedded in the cosmic microwave background. This is more about the evidence for Alan Gurth, Andrei Linde, etc’s inflationary model, which covers up some of the unsolved gaping hole left by the big bang theory. Yes, the article does talk about the fact that it confirms inflation, but they always mix the facts up with some misinformation. As of yet, there hasn’t been any direct observation of gravitational waves. Not that it matters much because gravitational waves have been confirmed by indirect observations before even this one. For example, by observing two neutron stars orbiting close to each other, they have found behavior that matches those predicted by the existence of gravitational wave. Seriously, research! Or am I asking too much for a reporter these days?
