The Universe in Your Hand by Christophe Galfard
New York : Flatiron Books, 2017, c2016.
First US edition
386 pages ; 22 cm
Christophe Galfard tries and mostly succeeds in leading the lay reader through the current state of knowledge about cosmology and astrophysics - taking the reader through Newtonian, Einsteinian and quantum physics along the way. It's an ambitious undertaking, and I think Galfard succeeds better than most at creatively introducing the reader to mind-bending worlds of quantum fields and some of the truly bizarre quandaries and realms of modern cosmology - dark matter, dark energy, and string theory.
His was one of the first books I've read about quantum fields where I started to just appreciate and even accept the way in which our "common sense" understandings of the world (which works fine on most of the scales we evolved in) are just not capable of reckoning with the way particles are manifestations of the quantum fields. It's heady stuff, and I'll probably reread those sections later to try and take in more of what they offer. Given the positives about this book, I have to qualify it with the following observation.
There is such a glaring mistake early in the book that I'm a bit befuddled that editors and early readers didn't check it. Galfard describes the future demise of our sun as being one where it "explodes, firing all the matter it was made of into outer space" (6). A while later he describes this ending as "spreading into space all the atoms the Sun has forged throughout its life while creating some more - the heaviest ones of all, such as gold" (19). This was so unlike any scenarios of the sun's demise I had ever read that I thought maybe I had misread previous books and explanations - or that the latest science was radically different. I searched books and online astronomy sites, and so far, I've found nothing to indicate that the sun will blow away all its mass or that a star of the sun's size can forge anything heavier than carbon in its last stages. From what I've read it will end up as a white dwarf that will then last for billions and billons of years as it slowly cools.
So I'll suggest the book for its navigation through quantum realities and string theory, but hedge my praise based on the beginning of the book.
