Establishing Dark Matter

Physicists think dark matter is a large component of the universe because they can't find enough mass in normal matter to account for the gravity required to hold the universe together as we see it.

The Alpha Magnetic Spectrometer, on board ISS, is used to search for dark matter by analyzing the components of cosmic rays, and it has produced an interesting result.  So far, it has detected more positrons than expected, and positrons could be indicators of dark matter.
