Dark Matter?

What is dark matter? I see it numorous times in video games as a reactive substance that is extremly powerful. Also I have heard about something called "Mass Effect?" What's that?  ??? ???

The existence of dark matter has been inferred by observations of the motions of galaxies and clusters of galaxies.  It only interacts with normal matter through gravity.  Dark matter particles are travelling through the earth all the time and being deflected slightly by its gravitational field.  It does not gather into small dense lumps like stars and planets.  It cannot be controlled and is only observable on the largest scales and so is the precise opposite of very powerful even though its effects on the overall large scale structure of the universe are significant.

that was discussed here

I believe that what Soul surfer said is right, though.
