Black Holes: A Traveler's Guide QUOTES

1 " Astrophysicist Stephen Hawking has proved that if two black holes unite, the surface area of the final black hole must exceed the sum of the surface areas of the initial black holes. For these reasons the total black-hole portion of the universe is ever increasing. "

2 " In the froth, space doesn't have a definite structure. It has various probabilities for different shapes and curvatures. It might have a 50 percent chance of being in one shape, a 10 percent chance of being in another, and a 40 percent chance of being in a third form. Because any structure is possible inside the singularity, we say the singularity is constructed from probabilistic foam, or quantum foam. Quantum gravity governs the probabilities for the various foam structures. "

3 " For relatively small stars, the Pauli exclusion principle keeps the electrons in a star sufficiently separated to prevent the star from contracting further after it has spent its fuel. In other words, the electrons counteract the crushing gravitational force. However, for stars more than about 1.5 times the mass of the sun (a mass known as the Chandrasekhar limit), this repulsive force would not be enough to stop stellar collapse. "

4 " Neutronium is so dense that a chunk the size of a thimble would weigh about 100 million tons. "
