Dark
Matter
Dark matter is the skeleton (scaffolding) of the
universe. Without dark matter there would be no galaxies, stars, or life. It doesn't interact with light.
It fills (fuels?) the force of gravity.
~23% of the
universe is dark matter, 4.6% is
atoms, and 72% is
dark energy

Physicists Set Strongest Limit On Mass of Dark Matter
ScienceDaily (Nov. 23, 2011) — Brown University
physicists have set the strongest limit for the mass of dark matter, the
mysterious particles believed to make up nearly a quarter of the universe. The
researchers report in Physical Review Letters that dark matter must
have a mass greater than 40 giga-electron volts. The distinction is important
because it casts doubt on recent results from underground experiments that have
reported detecting dark matter.
