Document Summary
Chapter 1 the scale of the cosmos: space and time. Cern is the home of the large hadron collider, the largest particle accelerator in operation today, which was designed to simulate the beginning of the universe. Bubble chambers were an important tool for the study of particle physics from the. 1950s to the 1980s, though they are now most likely to be seen as museum exhibits. The rotation of earth on its axis each 24 hours carries you eastward, as you cross the sunset line into darkness, you say that the sun has set. The average distance of the moon from earth is 380 000km. The average distance from earth to the sun is called the astronomical unit (au), which is 1. 5x108km = 150 million km = 1. 5x1011km. The solar system consists of the sun, its family of planets and some smaller bodies such as moons, asteroids and comets.
