In this experiment, a number model of gravitation and temperature is established by using Cavendish twist balance to test the gravity of shot at different temperature, the relationship between gravity and temperature is analyzed quantitatively, and it is concluded that, the higher the temperature of the object, the smaller the absolute value of gravity, and vice versa. It is further deduced that the greater the velocity of the object, the smaller the absolute value of gravity, and vice versa. This experiment fully explains why the gravity is very weak under the microscopic quantum scale and high temperature in the early universe. The result of this experiment is of great significance to improve the orbit calculation precision of the spacecraft (missile) of high temperature and ultra high speed.
