How can you post that without being embarrassed?
Shamelessly. With my highlighting:
I'm not in the least embarrassed.
...snip...
People see the word velocity in the translations and think
vector quantity, and for some weird reason they miss the way he refers to c, which is most definitely a speed. It's crushingly obvious he's talking about speed because he’s repeatedly referring to “the principle” or "one of the two fundamental assumptions". He was talking about the special relativity postulate, which is the constant speed of light. And it's even more obvious if you go back to the original German. What he actually said was
"die Ausbreitungs-geschwindigkeit des Lichtes mit dem Orte variiert." It translates into
the speed of light varies with the location. (LOL, some smart-alec has changed google translate to replace location with type. Try translating Orte on its own or use another translation facility). He said the speed varies with position and causes the curvilinear motion.
That is
Farsight's interpretation, but
Farsight doesn't really understand what Einstein was saying because
Farsight got lost at Einstein's equation (3).
Compare the highlighted German above with Einstein's discussion of this in
Die Grundlagen der allgemeinen Relativitätstheorie, in the last paragraph of §2:
Albert Einstein said:
Aus diesen Erwägungen sieht man, daß die Durchführung der allgemeinen Relativitätstheorie zugleich zu einer Theorie der Gravitation führen muß; denn man kann ein Gravitationsfeld durch bloße Änderung des Koordinatensystems „erzeugen“. Ebenso sieht man unmittelbar, daß das Prinzip von der Konstanz der Vakuum-Lichtgeschwindigkeit eine Modifikation erfahren muß. Denn man erkennt leicht, daß die Bahn eines Lichtstrahles in bezug auf K′ im allgemeinen eine krumme sein muß, wenn sich das Licht in bezug auf K geradlinig und mit bestimmter, konstanter Geschwindigkeit fortpflanzt.
Here's how that paragraph was translated in the definitive collection of Einstein's papers:
Albert Einstein (translated into English) said:
It will be seen from these reflexions that in pursuing the general theory of relativity we shall be led to a theory of gravitation, since we are able to "produce" a gravitational field merely by changing the system of co-ordinates. It will also be obvious that the principle of the constancy of light in vacuo must be modified, since we easily recognize that the path of a ray of light with respect to K′ must in general be curvilinear, if with respect to K light is propagated in a straight line with a definite constant velocity.
Note well that Einstein is discussing a ray of light in vacuo that "is propagated in a straight line with a definite constant velocity" in coordinate system
K but is curvilinear in coordinate system
K′. In other words, Einstein is discussing an observer-dependent effect.
When
Farsight tells us the effect we're discussing is a property of spacetime, not an artifact of how spacetime is interpreted by different observers using different coordinate systems,
Farsight is arguing with Einstein.
Farsight's been arguing with Einstein a lot.
Farsight has also been denying the first sentence of Einstein's paragraph, in which Einstein says gravitational fields are observer-dependent and can be produced by a suitable choice of coordinate system even in flat spacetime.
Farsight continued to deny those words of Einstein even after a simple concrete example was described in ample mathematical detail:
Can you show us where in the actual physics that Einstein uses a scalar quantity rather than a vector quantity?
No,
Farsight got lost at Einstein's equation (3), so 99% of Einstein's physics is incomprehensible to
Farsight. When the physics is presented in detail, as in the "
Farsight versus Einstein" links above,
Farsight dances the crackpot's polka: denial, scorn, condescension, ignorance, dishonesty, and projection. Like this:
How on earth can you dismiss Einstein just like that? We're talking about relativity and time here, it matters. What's the alternative, ignore him and lap up some moonshine about time machines instead? FFS Tubby, what kind of cargo-cult world do you live in? Don't bother answering that, nobody's going to listen to your Einstein was wrong tosh anyway.
Get lost, you got caught with your pants down when I quoted the later material, you're patently dishonest.
