In The Crowded Universe, renowned astronomer Alan Boss argues that based on what we already know about planetary systems, in the coming years we will find abundant Earths, including many that are indisputably alive. Life is not only possible elsewhere in the universe, Boss argues--it is common.

Boss describes how our ideas about planetary formation have changed radically in the past decade and brings readers up to date...

Proceedings from the 2012 Fourth International Meeting on Gravitation and Cosmology, focusing on accelerated cosmic expansion

This volume provides both an update and a review of the state of alternative theories of gravity in connection with the accelerated expansion of the universe issue. Different theoretical proposals exist to explain the acceleration in the cosmic expansion, generating the dark energy issue and opening the possibility to theories of gravity alternative to general relativity. Related issues such as the dark matter problem are also surveyed in order to give the...

Time. Gravity. Night. So much of what surrounds us feels familiar and mundane. But each is a wonder that reveals profound insights into the world around us.

C. Renee James's whimsical tour of seven everyday experiences--night, light, stuff, gravity, time, home, and wonder--opens the Universe to fantastical contemplation. Light? Although we need it to see, there's much more to it than meets the eye. Stuff? When it comes down to it, things are almost entirely empty space--99.9% nothing--especially when you get to the atomic level. Home? James's contemplation of our place in the...
