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...

According to a recent survey, the most popular question about science from the general public was: what came before the Big Bang? We all know on some level what the Big Bang is, but we don't know how it became the accepted theory, or how we might know what came before. In Before the Big Bang, Brian Clegg (the critically acclaimed author of Upgrade Me and The God Effect) explores the history of this remarkable concept. From the earliest creation myths, through Hershel's realization that the Milky Way was one of many galaxies, to on-going debates about Black Holes, this...
