In volume 2, BLINKI, ALIENNE and WHIZZY fly past the Moon, Venus and Mercury in their ultrasonic hyper fast propulsion spaceship at almost 3,000 kilometres per second and come close to the Sun which, as we know, is several millions of degrees hot. Ghost particles whizz past them and penetrate through their bodies. Even though the playful WHIZZY is very excited about this wild trip he still hopes to see his friends Molly, Nibbly and Buzzy back down on Earth again soon because he knows, of course, that there is hardly anything more important for children than having real friends you can rely on.

In 6 volumes which are complementary and interrelated, using humorous and exciting adventures in the universe, the latest scientifically proven findings are shown to encourage young readers and readers who are young at heart to become enthusiastic about a world which, thanks to scientific progress, has become more recognisable in many ways. The creation and dying of stars and black holes and their collisions described in volume 4 definitely has a fascinating effect on teenagers to the same extent as the appearance of supernova and quasars in connection with the time space problematic and the theory of relativity. Even the critical reference to evolution and the mostly cruel and stubborn "world of humans" are probably not particularly disconcerting to young readers, on the contrary they are more likely to be comprehensible and exciting.
