...you get very strange hypotheses like this: "Dark Energy May Be Consuming Dark Matter"

From a press release:

“Since the late 1990s astronomers have been convinced that something is causing the expansion of our Universe to accelerate. The simplest explanation was that empty space – the vacuum – had an energy density that was a cosmological constant. However there is growing evidence that this simple model cannot explain the full range of astronomical data researchers now have access to; in particular the growth of cosmic structure, galaxies and clusters of galaxies, seems to be slower than expected.”


Wow, if we were complaining about adjustable parameters before... well, in a way, this tells us that there was a way to falsify the cosmological constant model and it has to a certain extent been falsified, but this is also very much the usual reaction, to overlay more curves on top until it matches your complicated shape more closely.

(Not saying I blame them, but... holy crap, how many parameters are we going to end up with?)
