2019-04-03 | Two Unusual Galaxies Shake Up the Dark Matter Debate, Again | WIRED
'The mass of a dark matter halo varies from galaxy to galaxy, but it seemed like every galaxy must have at least some dark matter to keep its form. '
'Most cosmologists still believe that dark matter must exist, but some have splintered off to propose other explanations that explain away dark matter by modifying our understanding of gravity. '
'When it comes to the nature of dark matter, astronomers are still largely, well, in the dark. '
'The irony, the researchers say, is that the seeming lack of dark matter in these galaxies is strong evidence that it exists. '
'Will further observations of ultra-diffuse galaxies resolve the dark matter debate?'
