The Universe is a Machine is in the form of a treatise, and explores the `smoking gun' clue that a distinct mechanical process was present in the aftermath of the Big Bang, superimposed on the thermodynamic and nuclear processes associated with the evolution of the early Universe.This conjecture challenges the current scientific orthodoxy that antimatter was completely destroyed in the aftermath of the Big Bang. The clues for this conjecture are contained within the cosmic microwave background radiation echo left over from the Big Bang. A novel solution is proposed for what happened to all the antimatter, why it is still extant within the Universe, and why its presence has never been detected. The very profound deduced consequences of this are also explored, revealing new perspectives on aspects of the early Universe, including inflation, conditions surrounding primordial nuclear fusion, the formation of the first spinning galaxies or superstars, the formation of a cold dark zone, the formation of black holes in the centre of galaxies, the conundrum of dark matter, and a possible future doomsday scenario for the fate of the Universe. The Universe is a Machine may offer food for thought for some physicists who claim that aspects of physics are currently in a cul-de-sac and that a totally new perspective may be required. The perspectives contained in this book may be the first step out of that cul-de-sac. This innovative new book will appeal to scientists and engineers who have an interest in cosmology. It assumes prior knowledge of fundamental concepts in mechanics and physics, and a familiarity with elementary differential and integral calculus is required for the appendices. Explanatory illustrations are included.
