From our own experience and view of life on planet earth, all observers and objects are clearly moving in the universe in some way. For example, an observer on the surface of Planet Earth has a motion arising from the sum of the Earth’s rotation, the Earth orbiting the Sun, the Sun moving within the Milky Way, the Milky Way rotating and moving within the universe and so on. Clearly all bodies are dynamically moving in the universe.

The theory of Physics in 5 Dimensions (Pi5D) introduces the concept of all objects and observers having their own individual path with a common constant velocity c, a dynamic 5th dimension as judged from any local Galilean coordinate system rigidly attached to an observer, anywhere in the universe.

This new 5th dimension represents an addition to the existing four dimensions (three spatial plus time) of the current perspective of Physics in 4 Dimensions (Pi4D). With this theory every object has its own universal constant speed of light (c) to account for its energy and momentum, created from electromagnetic radiation (light) acting as de Broglie matter-waves with the properties of wavelength and frequency of quantum mechanics.

The relative velocity between any two bodies is dependent only on the tilt of the orbital planes with their respective paths of common constant velocity. The mass and angular momentum of each body are fixed constants and result in simple energy relationships; compared to Einstein’s relativity theory where mass has to vary with velocity to balance the energy relationships of Pi4D.

The definition of velocity vectors of Pi5D also defines the local frames of reference (local spaces) to be used for analysing the motion of bodies and a single set of “universal equations of motion” correctly forecasts the motion of all particles and bodies of the universe. The same basic fundamentals of Physics in 5 Dimensions applies to all nuclei, multi-electron atoms and to planets orbiting a sun.

The book Physics in 5 Dimensions (Pi5D) gives an exact insight into this more unified theory of physics.

The current view of classical physics is summarised for each of the many fields of physics covered in the book and the new perspectives of Physics in 5 Dimensions, the hypotheses developed and their results, are shown to comply with the fundamentals of physics and can be seen to follow as reasonable and logical extensions of the classical view.

The perspective of Physics in 5 Dimensions develops over many different fields of physics throughout the book and is to be judged on the complete work and the extent of the results. This book offers the reader an opportunity to refresh their view of classical physics as well as an introduction to the perspectives of Physics in 5 Dimensions; a more unified theory of physics.

The content of this website is based on a selection of short papers included in the book What's the Matter? that provides a concise and simple introduction to Physics in 5 Dimensions. Each topic on this website is complete in itself and can be read in any order. These papers offer an easy introduction to the theory of Physics in 5 Dimensions

Some papers of What’s the Matter? review the fundamentals of physics of Famous Physicists and show how alternative perspectives have resulted in the new hypotheses of the theory of Physics in 5 Dimensions; however without changing the fundamentals of classical physics.
