The standard cosmological model is the frame of reference for generations of scientists but some question its ability to accurately reproduce what is observed in the nearby universe.
Dwarf galaxies that orbit the Milky Way and the Andromeda galaxies defy the accepted model of galaxy formation, according to an international team of astrophysicists, and recent attempts to wedge them into the model are flawed, they believe.
David Merritt, professor of astrophysics at Rochester Institute of Technology, says their work pokes holes in the accepted model of the origin and evolution of the universe. According to the standard paradigm, 23 percent of the mass of the universe is shaped by invisible (insert your definition here) known as dark matter.
