Thank you Bojan. A vexing question apparently even for physicists with rather robust arguments being expressed at times. I will just have to consider two conflicting assumptions, a constant G and a variable G, in my work. A constant G means that the Earth maintains its mass throughout time and is why subduction had to be invoked to counteract the expansion that is evident in formation of the oceans. A variable G means that Expansion and Contraction could have alternated throughout time, and might help geologists who believe that both expansion and contraction have taken place on Earth. At the moment, reconciling the observations is difficult and we encounter anomalies and paradoxes that seem to defy explanation. Ernie.
