Relative Time Delay and Absolute Time Delay
This paper has explained that, the motion can be divided into two types, i.e. relative motion between two objects and circular motion unrelated to relative motion (also known as absolute motion). Time delay resulted from relative motion is referred to as relative time delay; time delay caused by circular motion is referred to as absolute time delay. Relative time delay refers to a time delay effect obtained by an observer when observing another reference system being in motion; absolute time delay refers to a real time delay of object being in motion. It is deduced that, the only way for human beings to achieve a real time delay situation is that: An observer can travel around the planet by spacecraft. The analyzed results show that, it is impossible for black hole to exist as a real matter. As a result, the time delay obtained after traveling around fixed star A1 by spacecraft shall be considered as the maximum absolute time delay obtained by human beings.
Constant Gravitational Mass of Moving Object and Variational Gravitational Field Deducing that Application Scope of General Theory of Relativity is Limited
This paper, based on simple examples, aims to show that the gravitational mass of an object is constant and that the distribution of gravitational field is associated with the motion of object. The formula for distribution of gravitational field during the motion of object has been deduced through variation in geometrical relation between gravitational lines. The paper analyzes the difference between gravitational mass and inertial mass of moving object in terms of size and direction and concludes that equivalency principle is false and application scope of general theory of relativity is limited.
