Dark matter still dark

University of Nottingham think that lithium near absolute-zero Kelvin can confirm or deny a gravitational scalar field. I mean - besides the Higgs, already well-confirmed and constrained (as opposed, say, to the neutrino).

I read some silliness in the press-release: a particle called a scalar field. Eerrrgh!! At least its title is good, reporting on the system rather than "in search of -" or, worse, "Is...??"

I remain unsure at what point the various funds will quit funding studies on dark-matter but, on the other hand, other establishments are still trying to constrain the similarly mass-bearing neutrino, which we know exists and is vital to explaining high-energy events like neutronstar-merger. Meanwhile modified gravity isn't going away (fair warning: they'd interviewed Gough for commentary, a Milgrombro until lately).

I do agree that a field might exist as isn't Higgs, which may account for "dark matter" and even for the neutrino itself. We may end up defining two forms of "mass"; maybe the neutrino has no Higgs mass but has relativistic mass? I have no clue. But then I'm a Byzantinist and applied-mathematician, not a cosmologist.
