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.
