By physics, a gravity lens should never form four distinct perfect images on the ordinal points of a compass around the gravity source, it should form a distorted Einstein Ring. There is something else at work here than the simplistic gravity lensing artifact being claimed. What is the focusing modality? Is gravity a quad-polar phenomenon? Or does is it mono-polar as all of our observations seem to show?
:-) good questions...I guess. Would love to know how and why but since I’m past the halfway point of my life, I’ll wait till I talk to my guardian angel. He’ll show me.
