    Dark matter galaxies located?

    Interesting. Paradoxically the story is about glaxies that don’t have any DM. Apparently these particular glaxies are atypical relative to glaxies where the presence of DM has been inferred through gravitational lensing.

    What? Never heard of glaxies before.

    If there’s a mod out there who can correct my spelling mistake in the title and add a question mark at the end then feel free.

    I bet you just wanted to put “uncorns” in a thread title.
    Anyhow, I find the speculation of antimatter galaxies to be very fascinating.

    If dark matter exists does that imply anti-DM?

    Not necessarily. It really depends on what the nature of DM is. WIMPs would likely come in matter-antimatter forms, but other candidates could be their own anti-particle in the same way that photons are.

    If dark matter exists could there be DM black holes or equivalent?
