Strange but true: dark matter grows hair around stars and planets (Synopsis) [Starts With A Bang]
“Few enterprises of great labor or hazard would be undertaken if we had not the power of magnifying the advantages we expect from them.” -Samuel Johnson
Dark matter may make up 27% of the Universe’s energy density, compared to just 5% of normal (atomic) matter, but in our Solar System, it’s notoriously sparse. In particular, there’s just a nanogram’s worth per cubic kilometer, which makes the fact that we’ve never directly detected it seem inevitable.

But recent work has demonstrated that Earth and all the planets leave a ‘wake’ of dark matter where the density is enhanced by a billion times or more. Time to go put those dark matter detectors where they belong: in the path of these dark matter hairs.

Dark matrix~ Abstractedly observant, waiting to be observed, harmonically sprung set and bound, creeping of ‘rooting’ a path of its charter, gaping through every hole with flesh as its martyr, channeling resonant flows of desire, swelling of clustered networks of fire, running streams of strings entwined as it coils, its elemental coating shell adds heat as it boils.
