Hairy dark matter is still dark matter, which is still a fudge

The solar system might be a lot hairier than we thought.” So says a recent report1 on a new theoretical study soon to be published in the Astrophysical Journal by Gary Prézeau2 from NASA’s Jet Propulsion Laboratory. His theory proposes the existence of long filaments of dark matter, which have a form similar to “hairs.” See Fig. 1 reproduced from the published report. If you thought dark matter couldn’t get any stranger you would be wrong. But what is driving these type of theoretical investigations?

Figure 2: Pie chart showing the alleged dark matter and dark energy percentages in the Universe

Dark matter is the alleged invisible, mysterious matter that comprises 24% of the total mass/energy content of the Universe. The matter that we are all familiar with, they say, comprises only about 5% of the mass/energy content of the Universe. The remaining 71% is the alleged dark energy, a strange anti-gravity-type energy that is allegedly driving the accelerating expansion of the Universe. See Fig. 2. Continue reading
