"Do robots have emotions? What would happen if you jumped into a black hole? Can plants ... hear things? Find the answers to these and even more far-flung questions in this quirky, super-stuffed curiosity quencher. Some questions have simple answers. And other questions? Well, it's complicated. That's where this book comes in. We're tackling head-scratching--sometimes serious and sometimes totally wacky--questions whose answers aren't so black and white. We'll dig into the possibilities, analyze the what-ifs, and give plenty of science to back it up." [Provided by publisher]
