Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

Was wondering if anyone has seen this done? Essentially I've tried plugging in the Schwarszchild exterior metric and getting a radial wave equation then taking a series expansion for small M (gravitating mass) and comparing that to the KG radial wave equation in a radial potential V(r) but i cannot seem to recover the linear energy term (grav KG equation seems to only provide E^2)

Any ideas/help would be...helpful!

Cheers
