• Black hole - "A black hole is a region of space from which nothing, not even light, can escape. It is the result of the deformation of spacetime caused by a very compact mass. Around a black hole there is an undetectable surface which marks the point of no return. This surface is called an event horizon." - Wikipedia

• Why are Supermassive Black Holes at Galactic Cores Spinning Faster than Ever in the History of the Universe? - "... in recent times a large fraction of the most massive black holes have somehow spun up. A likely explanation is that they have merged with other black holes of similar mass, which is a truly spectacular event, and the end product of this merger is a faster spinning black hole..." - The Daily Galaxy - May 24, 2011
  
• Pasta-Shaped Light from Spinning Black Holes Could Challenge Einstein - "Rotating black holes could leave a twisty signature on light escaping their gravitational maws. If this screwy light can be detected from Earth, it would give astronomers a new way to detect exotic black holes and a new test of Einstein’s theory of general relativity, says a team of physicists." - Wired Science - Feb 14, 2011
