I laughed and sighed when I read this. I have never been really happy about the alleged existence of matter that cannot be detected nor energy that has no known source. However for the last decade or two, cosmologists have been pushed into these enigmatic hypothetical features by what they believed to be the hard facts of cosmological measures, particularly those of the cosmic background radiation.
Now astronomers from the British Royal Astronomical Society, Utane Sangawit and Tom Shanks, have found that these measures were incorrect after all, and very much so. While the data is still insufficient, it is possible that we can in then scrap the mysterious dark side of the Universe off the equations needed to explain it.
According to Sangawit:More information at the RAS (found via SD).
If our result is repeated in new surveys of galaxies in the Southern Hemisphere then this could mean real problems for the existence of dark energy.
