While reading Slashdot today, I came across an article titled "Information Paradox Solved? If So, Black Holes Are 'Fuzzballs,'" which reveals some incredibly interesting information about black holes and how they are formed. The part of the article I most enjoyed is reproduced below:

In the classical model of how black holes form, a supermassive object, such as a giant star, collapses to form a very small point of infinite gravity, called a singularity. A special region in space surrounds the singularity, and any object that crosses the region's border, known as the event horizon, is pulled into the black hole, never to return.

In theory, not even light can escape from a black hole.

The diameter of the event horizon depends on the mass of the object that formed it. For instance, if the sun collapsed into a singularity, its event horizon would measure approximately 3 kilometers (1.9 miles) across. If Earth followed suit, its event horizon would only measure 1 centimeter (0.4 inches).

It's amazing to think that something as massive as the planet we live on would only make for a black hole slightly larger than a ladybug.
