Once the stars of the binary star system were consumed, the entire planetary system, dimmed. Fortunately, since the black hole was only formed from the mass of the Ultralisk, its surface area and power was weak. After it consumed the entire celestial body in the planetary system, it stopped drawing anything in.
Even though a black hole's gravitational pull was infinite, the amount of matter it could consume was limited. Once it hit its limit, the black hole would be converted into a white hole!
A white hole was a completely inverse entity to that of a black hole. It would spew out energy and matter until it evaporated away all of its mass.
Woosh!
