Making Sense of Modern Cosmology; The Once and Future Cosmos; by P. James E. Peebles; 2 Page(s)

Confused by all those theories? Good

The First Stars in the Universe; The Once and Future Cosmos; by Richard B. Larson and Volker Bromm; 8 Page(s)

Exceptionally massive and bright, the earliest stars changed the course of cosmic history

The Life Cycle of Galaxies; The Once and Future Cosmos; by Guinevere Kauffmann and Frank van den Bosch; 10 Page(s)

Astronomers are on the verge of explaining the enigmatic variety of galaxies

Surveying Spacetime with Supernovae; The Once and Future Cosmos; by Craig J. Hogan, Robert P. Kirshner and Nicholas B. Suntzeff; 8 Page(s)

Exploding stars seen across immense distances show that the cosmic expansion may be accelerating - a sign that an exotic new form of energy could be driving the universe apart

Cosmological Antigravity; The Once and Future Cosmos; by Lawrence M. Krauss, sidebar by Martin A. Bucher and David N. Spergel; 10 Page(s)

The long-derided cosmological constant - a contrivance of Albert Einstein's - may explain changes in the expansion rate of the universe

The Quintessential Universe; The Once and Future Cosmos; by Jeremiah P. Ostriker and Paul J. Steinhardt; 10 Page(s)

The universe has recently been commandeered by an invisible energy field, which is causing its expansion to accelerate outward

The Fate of Life in the Universe; The Once and Future Cosmos; by Lawrence M. Krauss and Glenn D. Starkman; 8 Page(s)

Billions of years ago the universe was too hot for life to exist. Countless aeons from now, it will become so cold and empty that life, no matter how ingenious, will perish

Is Space Finite?; The Once and Future Cosmos; by Jean-Pierre Luminet, Glenn D. Starkman and Jeffrey R. Weeks; 8 Page(s)

Conventional wisdom says the universe is infinite. But it could be finite, merely giving the illusion of infinity

The Universe's Unseen Dimensions; The Once and Future Cosmos; by Nima Arkani-Hamed, Savas Dimopoulos and Georgi Dvali, sidebar by Graham P. Collins; 8 Page(s)

The visible universe could lie on a membrane floating within a higher-dimensional space

A Cosmic Cartographer; The Once and Future Cosmos; by Charles L. Bennett, Gary F. Hinshaw and Lyman Page; 2 Page(s)

The Microwave Anisotropy Probe will give cosmologists a much sharper picture of the early universe

Echoes from the Big Bang; The Once and Future Cosmos; by Robert R. Caldwell and Marc Kamionkowski; 6 Page(s)

Scientists may soon glimpse the universe's beginnings by studying the subtle ripples made by gravitational waves

Exploring Our Universe and Others; The Once and Future Cosmos; by Martin Rees; 6 Page(s)

In this century cosmologists will unravel the mystery of our universe's birth - and perhaps prove the existence of other universes as well

Ripples in Spacetime; The Once and Future Cosmos; by W. Wayt Gibbs; 10 Page(s)

Physicists have spent eight years and $365 million building a radically new kind of observatory to detect gravitational waves. But will it work? A trial run put it to the test

Plan B for the Cosmos; The Once and Future Cosmos; by João Magueijo; 2 Page(s)

If the new cosmology fails, what's the backup plan?
