The Brill–Hartle gravitational geon construct as a spherical shell of small amplitude, high frequency gravitational waves is reviewed and critically analyzed. The Regge–Wheeler formalism is used to represent gravitational wave perturbations of the spherical background as a superposition of tensor spherical harmonics and an attempt is made to build a non–singular solution to meet the requirement...

The central claim is that Christian belief and practices are neutral or positively bad for your health, and that studies to the contrary are badly flawed, “weak,” or inconsistent with other studies and, hence, can be ignored.
