Macroscopic objects as we see them all around us are governed by a variety of forces derived from a variety of approximations to a variety of physical theories. In contrast the only elements in the construction of black holes are our basic concepts of space and time. They are thus almost by definition the most perfect macroscopic objects there are in the universe. ~ Subrahmanyan Chandrasekhar 1910 to 1995
