What is the reason that the Gravitational Constant (G) varies?

TL;DR

As the methods of measurement became more precise, the disparity in measurements of G by different laboratories increased, rather than decreased.

If G really not a constant then what are the implications in science?

You might be interested in this article: Why do measurements of the gravitational constant vary so much? In short,

"Once a surprising 5.9-year periodicity is taken into account, most laboratory measurements of G are consistent, and are within one-sigma experimental error limits,"

Between 1973 and 2010, the lowest average value of G was 6.6659, and the highest 6.734, a 1.1 percent difference. The difference between recent high and low values is more than 40 times greater than the estimated errors.
what is the reason we don't believe it is variable?

On PF, we don't make statements like that without citing the source.

What is your source that says this variation?

Rupert Sheldrake should not be taken seriously, especially not in the field of physics.
