A) the rotation curve of our Galaxy, in which orbital speeds of stars appear to obey Kepler's law. B) the rotation curve of our Galaxy, in which orbital speeds of stars in the outer regions of the Galaxy are significantly higher than is predicted by Kepler's law in which the value for the observed mass in the Galaxy is used. C) the unexpected absence of luminous matter (stars, etc.) beyond a certain distance from the galactic center. D) the high amount of interstellar absorption in certain directions.
