[QUOTE="ohwilleke, post: 5870119, member: 19562"] The press release at Science Daily notes near the end that: The wobbling observation is very likely to be real as it is a close analogy of the long known "cusp-core" problem with Cold Dark Matter. See, e.g., [URL]https://arxiv.org/pdf/1305.7452v2.pdf[/URL] But, the need for self-interacting dark matter (SIDM) to solve the problem is huge, because all astrophysically relevant parameters for SIDM have been ruled out by other data. See: Torsten Bringmann, et al., "[URL='https://arxiv.org/abs/1612.00845']Strong constraints on self-interacting dark matter with light mediators[/URL]" (December 2, 2016). Abstract: [B][/B] The conclusion of the paper notes that: [/QUOTE]
