dark-matter-free galaxy
(galaxy showing signs of no dark matter)
A dark-matter-free galaxy (galaxy that has no dark matter)
is a conception which inevitably presents itself as a possibility.
Finding some would offer evidence regarding dark matter's nature
(and would offer further confirmation that there is indeed something
unseen causing the phenomena ascribed to dark matter). Dark-matter-free
galaxy candidates have been announced (e.g., NGC 1052-DF2),
but such new determinations naturally lead to efforts to confirm
or contradict the claim.
