Ella is excited to get her own room, but Tilly is not as thrilled. She asks Slippy if he can make her a time machine to slow down time so tomorrow never comes. Slippy says the only place time shows down is around black holes. Tilly races off with Madhu to find one. Maggie tries to explain how time moves more slowly at the black hole and how time moves differently at home but it's very difficult to understand. Tilly runs off with Madhu to hide. Will Slippy and Ella find them in time to be home for dinner?

The year is 3021. The place is the Milky Way, where eight-year-old Ella gleefully heads out with her friends on exciting adventures of discovery. At only eight, she already knows quite a bit about space... but there is always more to explore!
