Brian Clegg's succinct expose of what science has often referred to as the weakest force but which science now suggests is the progenitor of all futures is the paradox of what is 'Gravity'. A clever admix of the historical and the more contemporary thinking that is further infused with detailed analysis, yet this is an eminently readable thesis that folds time and space into the inevitable dance between uncertainty and predictability, between general and special relativity and between action across the 'ether' and across dark matter. If a black hole is indeed a time machine, then gravity must be its timekeeper. I thoroughly recommend this book to all who thirst for knowledge.
Great book on what we know and what we don't know about gravity. It's a refresher on basic physics and the scientific process too! It is written in a very entertaining style and really lays out how our views of gravity have developed throughout history. It traces the understanding of gravity from Newton through Einstein to the quantum guys.
A great book - although I am a bit of a science nerd, I have actually read it twice. The author really lays out the whole "warping of space-time" concept that we have all heard about. I can't recommend it enough!
I am fascinated by gravity. I would like to understand not just how to accurately calculate its magnitude by Newton's formula or Enstein's General Relativity, I would like to understand how space-time is actually deformed by mass. How is the information that mass is present transmitted to space-time. So, I was disappointed that I didn't really learn anything new in Brian Clegg's book. I did not get my questions answered. The book begins with an interesting historical summary of theories of gravity. He eventually gets to general relativity. I didn't really learn anything new. If one does not have an understanding of Newtonian gravity then this book would be interesting. If one has never read about the development of general relativity, then the history is interesting. For readers who have previously read about Newton and Einstein, there is little new material. There is a very brief mention of quantum gravity and modified theories of gravity that may preclude the need for the invention of dark matter, but the word brief is important. This book is aimed directly at the non-mathematical science enthusiast who wants a historical perspective on gravity and is satisfied with a very limited description of general relativity or other modified theories of gravity. No math is provided. There are brief descriptions of gravitons without much discussion. I didn't get my questions on the mechanism for the deformation of space-time by mass, explained.
