AS A CONSEQUENCE:
all sinkholes on EARTH should be checked on additional gravity
Also earth seem to have internal Black Holes.! see Quantum FFF theory
Sunspot gravity interference as the origin of Supernova ejection velocity differences simulated for massive stars.
Example of velocity differences of Super Novas <a href="http://arxiv.org/abs/1503.02199" rel="nofollow">arxiv.org/abs/1503.02199</a> THE THREE DIMENSIONAL EVOLUTION TO CORE COLLAPSE OF A MASSIVE STAR (simulation by S.M.Couch at al.) and:
Dual disk shaped Starspot locations assumed to be the origin of gravity pencil interference (see arrows, according to Quantum FFF theory)
