What is dark matter?

Answer Posted / guest

objects in the universe from galaxies a million times
smaller than ours to the largest clusters of galaxies are
held together by a form of matter that is not what we are
made of and that gives off no light. This matter probably
consists of one or more as-yet-undiscovered elementary
particles, and aggregations of it produce the gravitational
pull leading to the formation of galaxies and large-scale
structures in the universe. At the same time these
particles may be streaming through our Earth-bound
laboratories.
