By Carolyn Cinami DeCristofano
Eighty pages that take one of the strangest ideas in space and make it clear to a fifth-grader, jokes and all.
It starts by taking the name apart, because a black hole isn't a hole and isn't empty. From there DeCristofano builds up what one really is, how a big enough star collapses into one, what its gravity does to everything nearby, and how astronomers found something they can't see. Michael Carroll's space paintings sit next to real telescope images, and doodled cartoons and speech bubbles run along the edges cracking jokes at the physics. There's a discovery timeline, a long glossary, and an author's note at the back.
It's for the child who's aged out of planet books and wants to know what's really out there. DeCristofano gives them real physics here, gravity, collapsed stars, light that can't get back out, in plain language and without watering it down. The doodles aren't decoration. They break eighty pages of hard ideas into pieces a child can take one at a time, and they make it okay to laugh at something this big. It's the kind of book a curious child dips into as much as reads straight through.
