In his 1920 book Einstein informs the gullible world that the speed of light is constant, invariable, because, if it is variable, w=c-v, then "this result comes into conflict with the principle of relativity". Is Einstein lying blatantly, Grok?
Albert Einstein: "If a ray of light be sent along the embankment, we see from the above that the tip of the ray will be transmitted with the velocity c relative to the embankment. Now let us suppose that our railway carriage is again travelling along the railway lines with the velocity v, and that its direction is the same as that of the ray of light, but its velocity of course much less. Let us inquire about the velocity of propagation of the ray of light relative to the carriage. It is obvious that we can here apply the consideration of the previous section, since the ray of light plays the part of the man walking along relatively to the carriage. The velocity W of the man relative to the embankment is here replaced by the velocity of light relative to the embankment. w is the required velocity of light with respect to the carriage, and we have w = c - v. The velocity of propagation of a ray of light relative to the carriage thus comes out smaller than c. But this result comes into conflict with the principle of relativity set forth in Section 5." http://www.bartleby.com/173/7.html
GROK
Einstein's claim in his 1920 book that the speed of light is constant is supported by extensive evidence, like the Michelson-Morley experiment and modern tests at Fermilab and LHC. These confirm light's speed as approximately 300,000 km/s in a vacuum, regardless of source or observer motion, forming the basis of special relativity. Variable speed of light theories exist but lack robust experimental support and are not mainstream. Accusing Einstein of lying seems unfounded, as his argument aligns with evidence and logic. The debate persists, but current data strongly favors a constant speed of light.

You use red herrings like a dishonest human, Grok. In his 1920 book http://bartleby.com/173/7.html Einstein claims that the variable speed of light, w=c-v in his notation, "comes into conflict with the principle of relativity". Is that true? Yes or no?
GROK
Yes
ME
Oh là là! This is Newton's variable speed of light, c'=c±v, Grok, from his emission theory. Fully compatible with the principle of relativity. Are you lying or are you incompetent?
GROK
Newton's emission theory, where light speed varies as c±v, aligns with Galilean relativity, not Einstein's special relativity, which requires a constant light speed (c). Experiments like Michelson-Morley (1887), De Sitter (1913), and Brecher (1977) confirm light's speed is constant, contradicting Newton's model. While your claim of compatibility holds for older relativity, modern physics, backed by evidence, supports Einstein. I'm neither lying nor incompetent—my response reflects the scientific consensus. If you mean Galilean relativity, you're historically correct, but it’s outdated.
ME
"If you mean Galilean relativity, you're historically correct"
Historically or otherwise, the result w=c-v http://bartleby.com/173/7.html is compatible with the principle of relativity while Einstein says it "comes into conflict with the principle of relativity". Blatant lie, Grok?
GROK
In Galilean relativity, w = c - v is compatible with the principle that mechanical laws are the same in inertial frames, allowing variable light speed. Einstein's 1920 claim that w = c - v conflicts with the principle of relativity holds in special relativity, where light speed is constant (c ≈ 300,000 km/s) for all observers, as supported by the Michelson-Morley experiment. The disagreement stems from different frameworks: Galilean vs. special relativity. Einstein's statement isn't a lie; it reflects his theory's postulates, backed by extensive evidence. Historical debates and modern variable speed of light theories exist, but special relativity remains dominant.

"Einstein's 1920 claim that w=c-v conflicts with the principle of relativity holds in special relativity, where light speed is constant"
Nonsense, Grok. w=c-v conflicts with the constant speed of light but was, is, and will always be compatible with the principle of relativity.
GROK
Einstein's 1920 claim that w=c-v conflicts with the principle of relativity holds in special relativity, where light speed is constant for all observers, as supported by experiments like Michelson-Morley. Your argument aligns with Galilean relativity, where light speed can vary, and the principle only requires invariant physical laws. The disagreement stems from different frameworks: special relativity includes light speed constancy, while Galilean relativity does not. Both perspectives are valid in their contexts, but special relativity is the modern standard, backed by extensive evidence.
ME
"Einstein's 1920 claim that w=c-v conflicts with the principle of relativity holds in special relativity, where light speed is constant for all observers"
You can repeat that countless times but it remains nonsense, Grok.
GROK
Einstein's 1920 claim that light speed is constant in special relativity is well-supported by experiments like Michelson-Morley, confirming c=300,000 km/s for all observers. Your critique, suggesting w=c-v fits the principle of relativity, aligns with Galilean relativity, where mechanical laws hold, and light speed can vary. However, special relativity, with its constant light speed, is the modern standard, backed by extensive evidence like Fermilab tests. Both views are valid in their frameworks, but dismissing Einstein's claim as nonsense overlooks the experimental support for special relativity. The debate reflects historical versus modern physics paradigms.
ME
Either Newton's variable speed of light, c'=c±v, is compatible with the principle of relativity (then Einstein is lying blatantly in 1920), or it "comes into conflict with the principle of relativity" (then Einstein is correct). Your red herrings are disgusting, Grok.
