Space time on the Poincare diagrams

Abstract

Relations between the experience of space technology and theory of space and time are found in this paper. A nontraditional approach to the concepts of space and time is introduced. The approach is based upon the the analysis of the detailed mechanism of radar measurement and nonlinear Doppler effects as measured by an astronaut. The Lorentz factor √1−v2/c2 and four-dimensional interval t2−x2/c2 may be interpreted from the point of view of a space technologist. A “geometrical mean” notion for computing time interval is introduced parallelly with the usual arithmetic mean formulas, giving results comparable with those of special relativity theory. Space time relationships are demonstrated on the Poincare diagrams.
