Astronomy, astrophysics and cosmology hold a great fascination for the general public.
The starting point for this work is the loss of brightness of the red supergiant Betelgeuse, which was discussed in the media at the beginning of 2020 as a candidate for a supernova. While the first part familiarises the reader with the basics of general relativity, the second part offers an insight into the life and death of stars. Using static and dynamic star models, the general theory of relativity is applied in the second part to discuss white dwarfs, neutron stars and black holes as the final remnants of a star, thus closing the circle with red supergiants.
Each chapter ends with a short summary that explains the key aspects without using formulas.
