One of the main principles on which the Global Positioning System (GPS) technology is based is the strict proportionality between the rates of clocks in relative motion. In recent work it has been demonstrated that relativity theory can be modified to incorporate this principle without violating Einstein’s…

The present work calls attention to an undeclared assumption made by Einstein in his landmark paper [Ann. Physik 17, 891 (1905)] in which he introduced the special theory of relativity (SR). The emphasis in textbooks and periodicals is always on his two postulates of relativity (the relativity principle…

According to the special theory of relativity (STR) the rates of clocks and energies of objects should change in direct proportion as their state of motion is varied. The rates of clocks should slow down by a factor of γ = (1-v2/c2)-0.5 when they reach a speed of v relative to the observer (c is the…

One of the most basic principles in science is the objectivity of measurement of physical properties. According to the special theory of relativity (STR), this ancient principle is violated for observers in relative motion since it predicts that they generally will disagree on the ratios of the lengths…

An effective means of incorporating the time dilation effect into relativity theory is to assume that the unit of time is directly proportional to γ (u) = (1-u2/c2)-0.5 on an object such as a light source that has been accelerated to speed u relative to the laboratory. In recent work it has been shown…
