Hi Christine, Dark matter can be a number of things. Neutron stars, asteroids, comets, dust clouds, etc. qualify. What they have in common is that they are hard to detect because they don't shine like stars. There is a lot of stuff out there that we can't see. In fact a lot more than we can see it looks like. It reveals itself by gravitational effects. Black holes are dark too, but they are in a special class because of their huge mass and gravitational field, and small physical size. They can gulp down objects the size of our sun with no trouble, and get stronger gravitational fields in the process. There is probably one at the center of our galaxy into which the stars spiral. It is a place where time, matter, and space are grossly distorted. I think Iggy knows a lot more about this than I do. Del
