The following definitions are used throughout the book "Physics in 5 Dimensions - Bye, bye Big Bang" and on this website about the Theory of Physics in 5 Dimensions:

• Fundamentals of Physics refers to the laws of physics (axioms) which are generally considered to be "true" in classical physics. The "truth" of an axiom may of course be founded on rather incomplete experience, and sometimes we assume the "truth" of a proposition then, at later stage, we see that the "truth" is limited and have to consider the extent of the limitation. For example, this is the case for the laws of mechanics of Galilei-Newton which can be regarded as valid only for a Galilean system of coordinates. The fundamentals of physics and associated laws have to be reconsidered when taking into account Einstein's Special and General Theory of Relativity.

• Classical Physics refers to the current view of the fundamentals of physics including for example Quantum Mechanics and Einstein's Special and General Theories of Relativity.

• 4-dimensional space refers to a Galilean coordinate system in which four coordinates (x, y, z, t) determine an event or, in other words, a point of the four dimensional space continuum as used in various forms by classical physics.

• 5-dimensional space refers to a 4-dimensional space with an additional 5th dimension property, a hypothesis that gives all particles and bodies their own individual path of common velocity c as judged from a Galilean coordinate system in 4-dimensional space.

• Physics in 5 Dimensions / The 5th Dimension refers to the perspective of physics as viewed from 5-dimensional space.

• Theory of Physics in 5 dimensions - In the book we apply the theory to a succession of different fields of physics, which produce a series of additional hypotheses which are "unexpected" compared to the view of classical physics however "reasonable" in that they comply with the fundamentals of physics. Together these inter-related hypotheses represent the Theory of Physics with the 5th dimension.

• Local space was developed from the de Broglie theory on "The wave nature of the electron", as described in his Nobel lecture from December 1929. The lecture explained how de Broglie originally developed his ideas on wave-particle duality. The size of a local space is determined by the extent of the paths of the objects orbiting within the local space.

• Scientific Objectivity is a characteristic of scientific claims, methods and results. It expresses the idea that the claims, methods and results of science are not, or should not be influenced by particular perspectives, value commitments, community bias or personal interests, to name a few relevant factors. Objectivity is often considered as an ideal for scientific inquiry, as a good reason for valuing scientific knowledge, and as the basis of the authority of science in society.

• Objective Physics is widely assumed to mean that points can be distinguished only by the values of physical fields or as the positions of physical objects, including measuring devices (Einstein, The Hole Argument - page 2).

• Transparent is an adjective implying that something is clear, obvious or can be seen through.
