Is string theory "ontologically grounded"? At the present time, the majority of string theorists say that dark-matter-compensation-constant = 0, i.e., gravitational energy is empirically conserved in the Newtonian approximation of general relativity theory. I say dark-matter-compensation-constant = (3.9±.5) * 10^-5 -- if I am wrong about this then I am forced to admit that my speculations concerning general relativity theory and string theory are wrong. What then?
The question is, in the words of Witten, "... what happens to Albert Einstein's conception of spaceetime?"
