The next segment describes now radio telescopes accidentally discovered pulsars and includes computer graphics to illustrate how the lighthouse theory describes the observed radiation from a pulsar. In the program, astrophysicists describe the properties and formation of black holes and computer animations illustrate various concepts about black holes. Computer graphics illustrate descriptions of stationary Schwarzschild black holes with their singularities and event horizons and the rotating Kerr black holes with their additional ergospheres. The program then mentions then mentions the postulated gravity waves and how the search to understand black holes may challenge our current laws of physics. The first segment of this program opens with computer simulation providing a spectacular flyby of all the planets of our solar system.
Astronomers explain the solar nebula theory that explains how our solar system was formed.
Computer graphics illustrate the spinning solar nebula, the accretion of dust particles, and the formation of the protoplanetary disk. Astronomers explain how they search distant stars to find evidence to support the solar nebula theory, looking for signs of planetary formation with infrared and radio telescopes to detect cooler dust disks around older stars. The program also summarizes the evolution of our solar system, describing the terrestrial planets and the Jovian planets, and looks briefly at asteroids, meteors, and moons. The program concludes with a summary of the solar nebula theory and the implications of that theory for finding similar planetary systems around the other stars in our galaxy.
