What's it like to go down a wormhole? Not the sort you'd find in a garden, but short-cuts through space and time. Well, Felicity Frobisher knows.
Poor Felicity. She's just trying to get ready to go to school when a three-headed alien from the planet Aldebaran-4 arrives in her bedroom and covers everything in dust.
But Aldebaran-4 is light years away - so how did he get there? Through a wormhole. This is advanced multi-dimensional physics for young readers. The science is so new, even physicists aren't completely certain about it yet. But Marcus Chown (who usually writes factual science books about mind-bending topics such as negative gravity, ripples in the universe and where all our atoms came from) has turned it into a fun, fast-paced story. As the Three-Headed Aldebaran Dust Devil explains, wormholes are like a pan-galactic underground system, and he takes Felicity with him - to the International Space Station, Hawaii and Aldebaran-4 itself.
The book ends with some really interesting facts about space. My favourite is that the first space rockets didn't have toilets so the astronauts had to wee in their space suits!
