Dubbed the "God particle" by Nobel Prize-winning physicist Leon Lederman, the Higgs boson is a hypothetical particle which, like divinity, is all pervading but undetectable. Scientists around the world race to find this clandestine particle. This book is about a different quest to find a different particle. This too is all-pervasive and totally clandestine. By revisiting the key experiments of the past, those that have shaped physics as we know it today, and re-assessing them in the light of a new theory based on a prime particle, we confirm the existence of the elusive God Particle. It's a particle belonging to an as yet undreamed of class of matter, many orders of magnitude smaller than anything we have even imagined. The theory based on this particle ultimately leads to an overarching but simple proposition that all of the phenomena of nature can be described in terms of one particle, one force and one law.
