Abstract

(i) LCDM, works on large scales but something is seriously wrong on halo scales
(ii) We claim that missing ingredient is gravitational quantum theory (GQT)
(iii) Gravitational quantum theory (GQT) shows that
(a) cross sections depend strongly on environment
(b) baryons can be dark!
– dark baryons are the “WIMPs” we have been looking for…
(iv) quantum dark matter (QDM) is not a theory. It is an inevitable consequence of applying quantum mechanics to gravity
(v) I will concentrate today on how GQT can explain the unusual dark matter fractions observed in some galaxy halos
