WiggleZ says dark energy is real.
So here's the rude question …. as a result of this study (and other available evidence from other sources) ..
Is Dark Energy real, (or not) ?
… and why, (or why not) ?
I'm still wrestling with my thoughts on this .. what do others think, and why?

Baryon Acoustic Oscillation allows us to verify high-z supernova type 1 distances which until recently were only confirmed to low-z values through other standard candle methods such as Cepheid variables.
From this we can say the
effects of something we term "Dark Energy" are real. It still doesn't however tell us what Dark Energy is.
As Leon Susskind points out Quantum Field Theory is ready made to explain what Dark Energy is, but predicts way too much of it when compared to what is observed in the Universe.
Hence the jury is still out.
