Find the answers to these and even more far-flung questions in this quirky, super-stuffed curiosity quencher. 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. In these pages, explore the deepest depths of the ocean, the farthest edges of our universe, the ancient past, and dreams of the future. Find out what’s stopping us from digging a hole right through the center of planet Earth. (And what it would be like if we could!) Tackle the ins and outs of living in virtual reality, find out whether fish feel wet all the time, and get a sightseeing checklist for a vacation to the moon.
