In 1959, the Soviet probe Luna 3 took the first photos of the far side of the Moon. Even in their poor resolution, the images stunned scientists: The far side is an enormous mountainous expanse, not the vast lava plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. When the Earth Had Two Moons is an astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists.

Message from Inner Space, is a chilling, end-of-the-world story of an impending ELE, but not from a comet or asteroid—from within. Physics PhD., Dr. Hope Leanders and her colleagues at SETI, detect a reoccurring signal that seemed to be coming from outer space. After further investigation, they find that the signal actually emanates from Earth, travels into space, then ricochets back to the ground, making it appear to come from space.

As a sci-fi author with a hit TV show, I have a few ideas about what alien invaders are supposed to look like. In my stories, they’re technologically advanced monsters, with tentacles, and no faces. Turns out I was right about the technology. And about how angry they’d be. But the way they look is more terrifying than even I could have imagined. They look exactly like us. Because they are us.

This audiobook begins with the question "Who am I?" and immediately sets off in an astonishingly original direction. Why didn't anyone before Harding think of responding to this question like this? It's so obvious, once you see it. Harding presents a new vision of our place in the universe that uses the scientific method of looking to see what is true. It turns out that the truth about ourselves is not only true but also very good, and breathtakingly beautiful. We live in a sacred, many-layered, living universe - or rather it lives in us.

Beliefs about the shape of the earth have varied over the millennia, but the Ancient Greeks were able to observe that our planet is round and even Eratosthenes attempted to measure its size. It was not until explorers had fully charted the globe that most people were really able to comprehend its spherical shape.
