The title is intriguing and revealing at the same time, just as the book is. Most of us understand that it required an almost impossible set of coincidences for me to be writing this and you to be reading this! In many ways, it is accidental. And despite the vast developments in science and improvements in technology across time, do we still really know much of the universe we exist in?
It is an awe-inspiring subject, and Alan Lightman uses a series of lenses to frame the universe in ways that give us some understanding about its origins and how it works. From the basic forces that underpin the functioning of the universe, to the way it is constantly changing, to my favourite part – the two paths that have we humans have taken to answering our questions – science and religion – both spiritual in their own right, to the symmetry in design that almost suggests an architect, to the scale that is vastly beyond what we can actually perceive in relation to our immediate world, to its paradoxical love for the predictable and the occasional unpredictable, to the ‘unseen’ but active world of waves and particles, the book provides us snippets of the knowledge that humanity has collected over the years about the universe it inhabits. It also gives us an idea of what we do not know.
