Precise Ideal Value of the Universal Gravitational Constant G

In this paper, we are going to rely on the first law in physics through which we can obtain a precise ideal value of the universal gravitational constant, a thing which has not happened so far. The significance of this law lies in the fact that, besides determining a precise ideal value of the gravitational constant, it connects three different physical disciplines together, which are mechanics, electromagnetism and thermodynamics. It is what distinguishes this from other law. Through this law, we have created the theoretical value of the gravitational constant Gi and we found it equivalent to 6.674010551359 × 10-11 m3·kg-1·s-2. In the discussion, the table of measurements of the gravitational constant was divided into three groups, and the average value of the first group G1 which is the best precision, equals the following sum 6.67401×10-11 m3·kg-1·s-2, and it’s the same equal value to the ideal value Gi that results from the law, as shown through our research that any other experimental values must not exceed the relative standard uncertainty which has a certain amount that is equivalent to a value of 5.325×10-5 and that’s a square value of the fine-structure constant.
