Dark matter (Introduction)

The more recent theories about the existence of dark matter are attempts to answer questions raised by findings that do not fit Newtonian or Einsteinian descriptions of gravity. A new paper proposes that gravity is variable. Stars that are moving too fast at the edge of a galaxy to be held to the galaxy by the current concepts of gravity are held by an increasing force of gravity. This suggests to me that the proposal a different 'unknown' force is making the universe expand at a faster and faster rate may be true.
