Ignorance is no basis for opinion Studying Einstein led me by natural progression to Sachs If anyone wants details of either s work all you have to do is read it Sachs is nothing but a first rate scholar Beginning in the 1950s by 2010 he had published upwards of 200 times on completion of Einstein s theory and related subjects articles in reputable journals and books by reputable science publishers Yes it is Nobel Prize quality It is an embarrassment that the physics community has become so closely knit that only one road is deemed worthy of not being labeled quackery the quantum road Yet Einstein himself largely credited with having given birth to that which would be labeled quantum insisted that quantum theory offers no useful point of departure for future development but rather that a complete theory would depend on finding the field equations for the total field having transformation group not any narrower than that of the continuous transformations of co ordinates This is what Sachs completed having shown Einstein to have been correct within 15 years of his death So you tell me why no one will read it
