n his inaugural lecture at Cambridge, Stephen Hawking talked of a complete theory. He believed then that we were on the verge of understanding the universe. He was right. What do matter, energy, and space have in common? Forces. Constructing the universe from forces leads inevitably to the physics of our universe. Not surprisingly, this physics has the same mathematical relationships and explains the same experimental results that we have already discovered. The difference between the standard model and the Simplest Universe Theory is one of interpretation.

A theory of the universe that depends only on real objects and not imaginary ones has no need to explain away negative probabilities and no need to invent particles that cannot be measured. A space that is made of two types of particles is able to explain gravity and electromagnetism. They can be observed in the measurement of electromagnetic and gravitational waves.

The Simplest Universe Theory requires only one assumption to create a universe that matches our own. It predicts the laws and formulas of classical physics and of Special and General Relativity. Virtual particles and particles with fractional electric charge are excluded by its initial assumption. The Simplest Universe Theory is both more restrictive and more successful than the Standard Model.

A new theory provides new opportunities. In this book, you will discover a new relativistic wave equation, a replacement for the Schroedinger and Dirac equations. You will see how nature determines the masses of particles ranging from the kaon to the Higgs bosons, and how to find the decay branching ratios of the kaon and the tau. You will understand how nature creates stable isotopes of the elements starting from oxygen. Most importantly, you will see that the universe in which we live is the only possible universe. There is no anthropic principle. The laws of our universe were not determined by a throw of the dice.
