Absolute time and absolute space — •Grit Kalies¹ and Duong D. Do² — ¹HTW University of Applied Sciences, Dresden, Germany — ²The University of Queensland, Brisbane, Australia

The kinematic concept of velocity led to the geometric mechanics of Newton, Lagrange and Hamilton [1] and to further geometric theories such as special and general relativity, according to which time and space are relative. A different picture emerges when velocity is described as a dynamic (energetic) state variable of a material object (system, body, elementary particle, etc.) and the dynamic role of velocity in a collision is taken into account: 'Velocity is a physical level, like temperature, potential function,...' [2]. The velocity as an intensive state variable of an object leads back to absolute time, absolute simultaneity and absolute space and to the insight that nature is more than geometry. [1] G.
