3-Space In-Flow Theory of Gravity: Boreholes, Blackholes and the Fine   Structure Constant
  A theory of 3-space explains the phenomenon of gravity as arising from the time-dependence and inhomogeneity of the differential flow of this 3-space. The emergent theory of gravity has two gravitational constants: G - Newton's constant, and a dimensionless constant - alpha. Various experiments and astronomical observations have shown that alpha is the fine structure constant 1/137. Here we analyse the Greenland Ice Shelf and Nevada Test Site borehole g anomalies, and confirm with increased precision this value of alpha. This and other successful tests of this theory of gravity, including the supermassive black holes in globular clusters and galaxies, and the `dark-matter' effect in spiral galaxies, demonstrates the validity of this theory of gravity. This success implies that Newtonian gravity was fundamentally flawed from the beginning.
