Consider two objects with the same mass m1 and m2 which are in a circular orbit with a speed v at a distance R from the center of gravity. This is a symmetrical situation. Figure 1 shows this the two masses m1 and m2 at the present position. The velocity of the two objects is counter clockwise. The point "O" is the center of gravity. The point o1 is the observed position of m1. That means it reflects a position in the past. The actual angle is a function of both the distance of the binary objects and the observer i.e. the earth. Secondly of the speed of light. Point o2 the observed position but for m2. When the speed of gravity is considered also the points o1 and o2 can be used, but now they are much closer to m1 and m2. The actual angle is a function first between the distance between m1 and m2 and secondly the speed of gravity. |
