This is a good example of theoretical dark matter that we really do not understand:
Nearby Triangulum II has astounded Caltech researchers with its super speedy stars. Our tiny galactic neighbor has only about 1,000 of them, compared to our haul of at least 100 billion. But Triangulum II has a tremendous amount of hidden mass.
They found the highest concentration of dark matter in any galaxy studied so far. However, French researchers from the University of Strasbourg contend that the gravitational tug of neighboring galaxies is what’s flinging the stars around.
Let’s check out the galactic ring on the next pag
