The Correlation Between Gravitational Constant and Distance from Matter

The value of gravitational constant has been measured after the 18th century by various methods (such as using the torsion balance, very cold atoms and atom interferometry) in the macroscopic scale, namely in the distance more than one micro meter from the matter. But its amount at the vicinity of matter (r<1Å or r < 1nm) has not yet been measured. It was not acceptable for me to use the current value of gravitation constant, which its value was derived in macroscopic scale, in the microscopic and subatomic scale. This was the idea that led to writing this article. Here we show that we are able to consider a large value for the gravitational constant, G, at the vicinity of matter (r<1Å). Here we show that there are no experimental barriers for this hypothesis.
