Default Do Einsteinians Understand Einstein's Relativity?

Does Steve Carlip understand Einstein's relativity?

http://arxiv.org/pdf/gr-qc/9909014v1.pdf
Steve Carlip: "It is well known that the deflection of light is twice that predicted by Newtonian theory; in this sense, at least, light falls with twice the acceleration of ordinary "slow" matter."

http://www.desy.de/user/projects/Phy..._of_light.html
Steve Carlip: "Is c, the speed of light in vacuum, constant? At the 1983 Conference Generale des Poids et Mesures, the following SI (Systeme International) definition of the metre was adopted: The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. This defines the speed of light in vacuum to be exactly 299,792,458 m/s. This provides a very short answer to the question "Is c constant": Yes, c is constant by definition! (...) Einstein went on to discover a more general theory of relativity which explained gravity in terms of curved spacetime, and he talked about the speed of light changing in this new theory. In the 1920 book "Relativity: the special and general theory" he wrote: "...according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity [...] cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position." Since Einstein talks of velocity (a vector quantity: speed with direction) rather than speed alone, it is not clear that he meant the speed will change, but the reference to special relativity suggests that he did mean so. This interpretation is perfectly valid and makes good physical sense, but a more modern interpretation is that the speed of light is constant in general relativity. (...) Finally, we come to the conclusion that the speed of light is not only observed to be constant; in the light of well tested theories of physics, it does not even make any sense to say that it varies."

Steve Carlip: incredibly confused and dishonest isn't he? Professor of physics at the University of California, Davis.

Kip Thorne doesn't know that Newton's theory did predict deflection (half the deflection predicted by Einstein's relativity):

http://commons.erau.edu/cgi/viewcont...ss-proceedings
Kip Thorne: "A second crucial proof of the breakdown in Newtonian gravity was the relativistic bending of light. Einstein's theory predicted that starlight passing near the limb of the sun should be deflected by 1.75 seconds of arc, whereas NEWTON'S LAW PREDICTED NO DEFLECTION. Observations during the 1919 eclipse of the sun in Brazil, carried out by Sir Arthur Eddington and his British colleagues, brilliantly confirmed Einstein's prediction to an accuracy of about 20 percent. This dealt the final death blow to Newton's law and to most other relativistic theories of gravity."

Illiterate Kip Thorne is a crafty moneymaker, a famous teacher, and will be given the Nobel prize:

http://cornellsun.com/2016/04/07/ren...-interstellar/
"Thorne helped produce Interstellar and co-found the Laser Interferometer Gravitational-Wave Observatory, which successfully detected gravitational waves for the first time in February, according to the University. Thorne used Interstellar to explain gravity, black holes and the warping of time and space."

https://www.theguardian.com/science/...he-nobel-prize
"Gravitational waves: who should win the Nobel prize? ...in brief poll of physicists, three names were cited instantly. These are Rainer Weiss of the Massachusetts Institute of Technology, Kip Thorne and Ronald Drever of the California Institute of Technology, the three founders of Ligo, the Laser Interferometer Gravitational-wave Observatory in the US."

We all live in Einstein schizophrenic world don't we:
