Varying gravity : Dirac's legacy in cosmology and geophysics

Author: Helge Kragh
Publisher: Cham : Birkhäuser, 2016.
Series: Science networks historical studies, volume 54.
Edition/Format:   eBook : Document : EnglishView all editions and formats
Summary:
The main focus of this book is on the interconnection of two unorthodox scientific ideas, the varying-gravity hypothesis and the expanding-earth hypothesis. As such, it provides a fascinating insight into a nearly forgotten chapter in both the history of cosmology and the history of the earth sciences. The hypothesis that the force of gravity decreases over cosmic time was first proposed by Paul Dirac in 1937. In  Read more...
