A 24 page summary and condensation of 50 years of one man's thoughts and calculations in cosmology and particle physics. It is a beautifully written and concise work from an inventive engineer who looked differently at the central issues and problems linking these fields. Gravity, he proposes, is caused by mass shading out a pervasive backpressure from the expanding universe - sounds bizarre, but stay with it and see where it goes and what is explained. The author died in 1994, aged 80, this book was his last publication.
