The expanding Universe, the curved space, the black holes that devour everything, the acceleration of the flow of time, the yellow light that is actually blue and red, the path that is straight yet returns to its beginning, the shrinking of the measuring tape the closer it is to the ground, and how we are all made of stardust are some of the topics this book addresses.

Step into the mysterious world of thought bubbles. Explore with Alice of the Mind the land of tiny beetles and their unpleasant professor. Meet the friendly computer, Kompi, and travel with his powerful spaceship into the depths of the Universe.

Visit the Moon, walk in Space, admire the stars… But be careful: You must heed Uncle Albert's advice and stay away from black holes!

The story is action-packed. It entertains readers—both children and adults—while introducing them to the wonders of Einstein's General Theory of Relativity.
