New Galaxy Discovered That's Light on Dark Matter

From New Atlas:

Some of the strongest evidence for dark matter to date has been discovered – and ironically, that's thanks to its absence. In a pair of studies published this week, astronomers have shed new light on dark matter through close observation of a galaxy previously found to have very little of the stuff, while the same team found a new example of a similar oddball galaxy.

It's generally believed that galaxies are held together through the gravitational influence of clumps of dark matter, so to find a galaxy with little to no dark matter was a surprise. And while it might sound like a strike against the theory, it actually ends up supporting it.

    If the galaxy in question is light on dark matter (and Wikipedia seems to have doubt about that FWIW and it might not be much), does that mean that a galaxy that has too little detectable matter and too much undetectable matter a galaxy that is dark on light matter?

    TFA does mention "galaxy Dragonfly 44 [keckobservatory.org], which has the exact opposite problem of being composed of 99.99 percent dark matter" but they were light on details of the dark galaxy.

    If dark matter shits in the woods, will it make a smell?

      I don't know. But you appear to believe that yours does not. Self-deception is the worst kind of lie.

          Old enough that I could be your father. In fact, I (or a cast of thousands) might well be, given what a whore your mom is.
