    The fundamental phenomenon of dilation explains galaxy rotation curves/dark matter. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A 2 axis graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated.
    Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
    The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. In other words that mass is all around us.
    Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter, in other words they have normal rotation rates. All binary stars have normal rotation rates for the same reason.

      no, time and space dilation aren't related to DM or galactic rotation curves.

      @@JenFoxBot It's not a matter of opinion, dark matter is dilated mass. The fact that very low mass galaxies have predictable star rotation rates is virtual proof, there can be no other realistic explanation

    Where did you obtain samples to study in your Dark Matter Lab? 🤔

      we built detectors that could detect particle collisions. there's no "sample" of dark matter, but we did calibrate our detectors with radioactive material to make sure we could detect particle collisions!
      We used what's called a "time projection chamber" which you can learn more about here: en.wikipedia.org/wiki/Time_projection_chamber
