Red Limit

The acclaimed science writer presents “an exceedingly vivid history of modern astronomy and cosmology, told in entertainingly biographical terms” (The New York Times).

Hailed as “the best science writer of his generation,” Timothy Ferriss is renowned for his ability to discuss the complexities of outer space in ways that are lively, illuminating, and accessible. In The Red Limit, he takes readers on a journey of discovery as a variety of scientific breakthroughs lead us to glimpsing the edge of the universe (Washington Post).

For centuries, it was assumed that our universe was static. In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. Ferriss delves into this revolutionary discovery, its historic ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.
