Cosmologists for a long time have been intrigued by the question of why life appeared so late in a universe which has been expanding for 20 billion years, and why the density of matter in the universe is so small that successive generations continually relive Pascalian anxiety in their experience of the emptiness of infinite spaces. Modern cosmology supplies a partial explanation. Even if life were to develop in only one place, a large and old universe would have been required. Billions of years of cosmic evolution are necessary for the appearance of carbon producing stars, an indispensable element for the rise of known forms of life.
