A single point of infinite density and mass. Blackholes mass is so great that nothing can escape it's gravitational pull, not even light.
Blackholes are supposedly a reality but there is no way (currently) to prove that they are what they are. Blackholes are created by a star or planet of great mass exploding and then collapsing in on itself creating a gravitational pull that just pulls everything in more eventually ending in a blackhole. Blackholes are often identified by circles of light that orbit them because of the gravity. Blackholes also give off X-Ray and infared signals making them easier to discover.
Blackholes are often theorized as tears in the time-space continuum meaning they can be portals to other points in space or time. Many sci-fi books and movies theorize blackhole possibilities, such as L. Ron Hubbard's "Mission Earth" novels using blackholes as an energy source.

Apparently in the black community, this is a racist term because it has the word "black" in it without any words of praise surrounding it. Because of its political incorrectness, please note that it has now been renamed an African American Quantum Singularity.
John Wiley Price, the Mayor of Dallas and a black judge recently were offended and demanded an apology (no, I'm not making this up) for a white councilman referring to the traffic office as a "black hole" where paperwork is sent and never seen again. "How would you like it if I called it a 'white hole'?" Mr. Wiley-Price immediately retorted. Next on the list: Blackjack, Blackberry and Blackbird.
