Jürgen Beetz first shows the origin of the imagined stories of physics from the Stone Age, as much of it is so simple that even Stone Age people could have understood it. Following this, the author examines the universe and its components: moons, planets, stars, galaxies, etc. This leads to questions about its structure and dynamics: Is the universe eternal, endless, constant? None of that: It has a history of origin, it is expanding and changing - partly due to still unexplained causes. He places special emphasis on the expansion of the universe and the resulting consequences.
