The Substance of Spacetime: Infinity, Nothingness, and the Nature of Matter by Andrew M. Ryan is the second edition of Ryan’s work of theoretical physics and is now available where books are sold. This iteration of the book has been fully revised with a completely new final chapter that considers several of the current puzzles being debated today by the leading cosmologists. In this book, Ryan proposes a simple, physical model of spacetime as the basic substance of the universe.
If spacetime does not exist, it certainly does so in an unusual way. It curves and bends in response to massive objects. It warps in response to high velocities. It prohibits faster-than-light travel. What are we to make of the curvature, the warping, and the pressure of nothingness itself, a mere abstraction? The Substance of Spacetime sets out to investigate these questions and the answers are truly astonishing. Treating spacetime, not merely as a geometric abstraction, but as a real physical substance, opens a window onto reality that would otherwise be impossible to even contemplate.
If spacetime exists, everything changes.
