What If The Moon Fell To Earth?
Sometimes asking crazy questions is the best way to learn about the world.
The moon probably won’t crash into Earth anytime soon. It’s actually moving away from the planet, for now at least, and that’s mostly a good thing. Gravity would rip the moon into thousands of asteroids as it neared Earth, and it wouldn’t take long for them to reach the planet’s surface.
For the last four years, the folks at What If have been answering wild hypothetical questions like this in some of the coolest science videos on the web, amassing a following of some 25 million people. Now, fans of this award-winning video series will be able to enjoy What If's epic journeys of imagination in a whole new way! Say hello to What If 100, a collection of What If's most popular episodes... in book form!
Exploring what could happen if the moon hit the Earth is just one of the questions What If 100 explores. Other fascinating hypotheticals include: What if the sun exploded? What if we built a ringworld in space? What if we knew the time we go extinct? What if we had working quantum computers today? And many more!
