March 5, 2013 > Dark Matter Dark Matter Submitted By Chabot Space & Science Center Mysterious dark matter and dark energy are aspects of our Universe that we cannot see, taste, or feel, but they are very important: dark matter keeps galaxies gravitationally bound, and dark energy is accelerating the expansion of the Universe.
