Dark matter

Dark Matter is an obstacle in Super Mario Galaxy, which appears in Bowser's Dark Matter Plant. It can be found in patches, and has a swirly, purple and black appearance to it. Bowser was generating Dark Matter at his Dark Matter Plant in order to destroy the whole galaxy in order to create his new one. Dark Matter acts similarly to Poison Water. If Mario or Luigi touch any Dark Matter, they will sink into it and lose a life. Dark Matter can also burn holes in the ground that will make Mario or Luigi lose a life should they fall into one.
