+'''Einstein's Lost Key: How We Overlooked the Best Idea of the 20th Century''' is a 2015 popular-science book by the German physicist and science writer [[Alexander Unzicker]]. Published on 28 November 2015 by CreateSpace Independent Publishing Platform in a 236-page paperback edition (ISBN 978-1519473431; ISBN-10 1519473435), it argues that Albert Einstein's early, and later abandoned, treatment of gravitation as a spatially [[variable speed of light]] was the more physical of the two routes Einstein took toward a theory of gravity, and that its premature abandonment cost twentieth-century physics its best idea. An updated and revised edition appeared in 2022, and the book is also available as a Kindle e-book and as an Audible audiobook.
-KIRKUS REVIEWS: ...the author’s ideas are engaging and he presents them well. [...] turns into a screed against the scientific establishment.
+The book appeared in the centenary year of the completion of the [[General Relativity|general theory of relativity]] and is the popular counterpart to Unzicker's own technical work on [[Mach's principle]] and variable-speed-of-light gravitation. It followed his two earlier critiques of contemporary theoretical physics, ''[[Bankrupting Physics]]'' (with Sheilla Jones) and ''[[The Higgs Fake]]'', both of which drew sharp reactions from the physics community.
