Black Holes and Uncle Albert
More astonishing discoveries by the famous scientist, Uncle Albert, and his niece, Gedanken.
The exploding Universe, wonky jelly space, black holes that swallow up everything, speeded-up time, light that is yellow but also blue and red, the path that is straight but doubles back on itself, tape measures that shrink when you take them downstairs, and how it is that you are made of stardust.
Enter the mysterious world of the thought bubble. Visit the moon, go for a space walk, marvel at the stars. BUT BE WARNED: KEEP CLEAR OF THAT BLACK HOLE!
