https://photos.app.goo.gl/vxxtESuy1upGdsHT8 As shown, we have constructed a very simple Sun-Earth model. If the speed of universal gravitation is equal to the speed of light, the gravitational force of the sun will reach the earth with a delay of 8 minutes, then the gravitational force of the sun on the earth will come from S1 instead of the real position S0, so there will be a component F1 opposite to the revolution velocity of the sun. Under the action of F1, the earth will move to the left as shown in figure (a). Finally, Earth would follow S1, as shown in figure (b), which is inconsistent with the real solar system. How can we interpret this Sun-Earth model in terms of GRT? That is: under this gravitational delay, according to the calculation of classical mechanics, the orbits of the planets in the solar system will no longer be stable. How does GRT eliminate the influence of this gravitational delay?
