Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented it in 1915. Their work has uncovered a number of the universe's more surprising secrets, and many believe further wonders remain hidden within the theory's tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma, fueling a century of intellectual struggle and triumph.
Einstein's theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics, yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler's Germany, hounded in Stalin's Russia, and disdained in 1950s America. Even today, doctorate students are warned that specializing in general relativity will make them unemployable.
Despite these pitfalls, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein's theory.
We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.

A Love Letter to General Relativity
This is quite an unusual science book, quaint and pleasant. The author’s love of relativity clearly comes through in the rich writing and narration. The book contains yet another history of modern physics, but is unusual in having General Relativity as the focal point of the historical developments. This is unusual because General Relativity wasn’t actually such a focal point, quantum physics and particle physics were at center stage and General Relativity was a side-player at best. Yet, this odd viewpoint is still enjoyable and interesting. This is also one of the least equation burdened book in this genre.
Unfortunately, General Relativity is not really a perfect theory. We know the theory must be wrong. The theory is non-quantum and stubbornly refuses to quantize. The book was not very thought provoking, as it praised General Relativity instead of delving into its weaknesses. Certainly it is exploring the weaknesses and assumptions of Relativity that will lead to unification.
Often books with lots of science and math don’t do well in audible format. This book is not about the science or math of the theory, but instead describes the personalities and stories surrounding General Relativity. This works very well in audible format and the narration is excellent, slow, clear and even passionate.

Biography of Einstein's Relativity
This is a beautiful, human account that was a great surprise to me and I have listened to it about 4 times. It has the basic science and the human story as well which makes it so much more intelligible and personally valuable. This is an incredible story when you consider all that has been involved over the past century.
At this level: What is an *equation*? In and of itself what is the deepest knowledge that Relativity is pointing out to us ? :-)
