The Physics of Bodies in Real and Imaginary Spaces attempts to assess basic phenomena such as space, mass, velocity, energy, and momentum based on what nature reveals to us, and propose explanations for why the world behaves as it does. It begins by discussing how the evolution of numbers and number systems has expanded our awareness of the physics occurring around us. It talks about the initial connection between numbers and objects, and discusses how providing closure for mathematical operations such as addition, subtraction, multiplication and division expanded number systems with numbers that initially seemed abstract, but were later found to have physical significance.
Using this model, The Physics of Bodies in Real and Imaginary Spaces proposes that the existence of imaginary numbers implies that a physical realm built of imaginary numbers complements the real world made of real numbers that we take for granted as the entire world. It proposes that the universe is made of real space that it calls the apparent world, and imaginary space that it calls the hidden world. From this premise, it describes the coordinate systems that define each space and how the spaces relate to each other.
The Physics of Bodies in Real and Imaginary Spaces talks about apparent (real) world mass and its connection to the hidden (imaginary) world through a constant hidden world velocity it possesses. It shows how using velocities that have both apparent world and hidden world components naturally produce expressions of relativistic concepts such as length contraction and time dilation.
Finally, The Physics of Bodies in Real and Imaginary Spaces considers the likely properties of hidden (imaginary) world mass and shows that hidden world mass particles moving within the hidden world project momentum into the apparent world. It suggests how the momentum projected into the real world by the imaginary mass moving in the hidden world could be the electromagnetic radiation seen in the apparent world.
