Ricardo read this excerpt from A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano. Discoveries of black holes exploded in the late 1900s and early 2000s. What scientists found reads like a cast of characters for a mixed-up fairy tale. First they discovered the small ("Baby Bear") black holes, then the giant "Papas." But where were the medium "Mama Bear" black holes? It just didn't make sense that there would be smalls and larges but no mediums. Astronomers began the search, and found them. There's just one size that still hasn't been found, even though it has been predicted. The tiniest of all, the "Tom Thumbs" of the black-hole world, have yet to be discovered—if they even exist.
