Im Schwarzen Loch ist der Teufel los

Everything about space – scientifically grounded and easily understandable. How warm is it in space? Are black holes really black? And why do astronauts age more slowly? Ulrich Walter is one of eleven Germans who have been to space. During his mission with the space shuttle Columbia, he gained experiences that most of humanity can only dream of. The astronaut explains all the essential information about the world and the universe in a clear and entertaining way – from the theory of relativity to dark matter. Along the way, he reveals what might have happened before the Big Bang, whether his American astronaut colleagues actually landed on the moon, and how an alien invasion would really unfold. With numerous black and white illustrations.
