Hi everyone - I'm having some trouble with the real concept behind "degeneracy" of dark matter. I've heard of degeneracy before in maths (eg. a 'point' is a degenerate 'circle'), and in physics (eg. energy level degeneracy in atom shells), but I don't quite see how either of these work when we're talking about dark energy. From what I understand, in this context degeneracy is a 'bad' thing - but is it anomalous to error, arbitrary-ness, or the maths/physics definition?
