Apparently he does.
Even your link disdains from stating a specific mass ... even though your link uses electron-volts as a unit of mass ...
If mass is zero, then gravity is zero ... the V(r) we're using is always equal to zero for all r≠0 when M=0 ... del or no del ...
The State of California expects 15-year-old children to understand this ...
