Why is the earth far from the sun

Both the sun and the earth are radiating, and there are mass and energy conversions. Radiation is a process in which mass is converted into energy. The conversion of mass and energy follows Einstein's mass energy equation: E=mc ^ 2. In other words, the mass of the system composed of the sun and the earth is decreasing. The system composed of the sun and the earth follows the system constant equation I summarized: M ^ 2R=Q, Q is a constant, M decreases, R will increase, and the radius of mutual rotation of the system composed of the sun and the earth will increase, and the resulting result is that the earth is away from the sun, which is the real reason why the earth is away from the sun. According to the law of universal gravitation, we can also know that when the distance between two mutually rotating objects increases, the rotation speed will inevitably decrease, and the rotation speed will decrease. We can also conclude that the speed of the earth's revolution around the sun is also decreasing. It can be inferred that the moon is far away from the earth and the solar system is far away from the center of the Milky Way. The same reason is why the universe is expanding.
