Dark matter is a sphinx (Oort 1932; Zwicky 1933; Rubin & Ford 1970; Tyutchev 1869). Despite ingenious hunting strategies, we continue to chase after this notoriously elusive creature within the dark zoo (Feng 2010; Fan et al. 2013). In the sky, there are X-ray “mice” (Gaensler et al. 2004), radio “snakes” (Uchida et al. 1992), even an optical “Crab” (Rosse 1844; Mitchell 1855). The latter may have been a “pineapple”, as a matter of fact (Dewhirst 1983).
Non vale:
A dark matter creature should be unique in its peculiarity. When finally corralled, we conjecture pareidolically that – under extremely ?nely tuned conditions – dark matter sub-substructures might resemble a “winged horned lion” with a “serpent” for a tail, whose contours become apparent roughly at q times the free streaming scale ?
