Black holes suck in the Nobel prize for physics

BLACK HOLES are some of the universe’s most exotic objects. They are so dense that nothing, not even light, can escape their immense gravitational pull. At a black hole’s centre is thought to be a point of infinite density, called a singularity, where the known laws of physics break down.Understanding these dark cosmic objects has been a decades-long effort. On October 6th the Nobel-prize committee of Sweden’s Royal Academy of Science awarded the most famous honour in physics to three of those who have led that effort.
