"Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes ""the road less travelled"": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli."

Reviews for Quantum Space: Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe

...if you have enjoyed/got through popular science books about such areas as strings and superstrings, time, and the God particle, here is a fine addition to the oeuvre. * Ian Francis, School Science Review * There is no doubt that Jim Baggott is an excellent popular science writer, and Quantum Space is the first complete and approachable account to a quantum theory that delves deep into the quest to resolve one of the great unanswered problems of modern physics: How can general relativity be made compatible with quantum mechanics? Baggott proposes Loop Quantum Gravity, which in our mind is one of the best explanations for anyone who wants to understand more about our puling universe ... It's a triumph. * All About Space Magazine * There's no doubt that Jim Baggott is one of the best popular science writers currently active ... [he] has done a huge favour for anyone who really wants to understand modern theoretical physics, giving a much better understanding of this fascinating attempt to deal with a central requirement to explain the workings of our universe. It's a triumph. * Brian Clegg, popularscience.com * A lucid exposition of loop quantum gravity and the search for the structural space, time and the universe focusing around the work of Lee Smolin and Carlo Rovelli. * David Lorimer, Paradigm Explorer * The discovery and development of Loop Quantum Gravity has been a great adventure. Jim's story beautifully captures its insights and excitement. * Carlo Rovelli, author of Seven Brief Lessons on Physics * ...if you have enjoyed/got through popular science books about such areas as strings and superstrings, time, and the God particle, here is a fine addition to the oeuvre. * Ian Francis, School Science Review * There is no doubt that Jim Baggott is an excellent popular science writer, and Quantum Space is the first complete and approachable account to a quantum theory that delves deep into the quest to resolve one of the great unanswered problems of modern physics: How can general relativity be made compatible with quantum mechanics?
