Cosmic Spacetime

Cosmology has transformed into an exact science over the last hundred years, yet most accounts of that transformation overlook the spacetime that cosmologists study. This book fills that gap by examining the cosmic spacetime directly. It reviews the expanding body of observational evidence that justifies using the well-known cosmological solution of Einstein's field equations not only to sharpen the standard model, but also to test its underlying assumptions more thoroughly.

Moving from the tiniest scales to the largest, the author traces connections between the observable universe and the core principles of fundamental physics. Along the way, the book profiles the key researchers whose work shaped the field, placing their ideas within the technical framework of modern cosmology.

The text assumes a graduate-level background in physics and astronomy, and readers with that preparation should be able to follow its arguments throughout.
