Delusional, because the “Starmaker” troll actually thinks he knows science when he has not the shadow of a trace of a clue about it. Anti-semitic, because he thinks his utter lack of understanding of science has anything to do with the fact that it was someone from a Jewish family (*non-religious* Ashkenazi, BTW) who first proposed the concepts that he is unable or unwilling to understand. Nonsense, because he is completely missing the point, which is: Einstein did his all thought experiments *based on prior experimental evidence*. Regarding light, it is really very simple: How can and how do we get information about events in the first place? Primarily by light; in general, electromagnetic radiation. Either emitted originally from there (e.g., stars) or reflected back from there (e.g., planets and moons). So the speed of light and the *experimental fact* that it is limited and the same for all inertial observers, do matter. For example, you will not realize that the Sun does not longer exist before about 8 minutes later than it ceased to exist there, because it takes that time for the information of that event to travel to you. IOW, your Now *here* is different from the Now *closer to the Sun*; doubly so if the Sun were considerably moving away from you or towards you. > "If the facts don't fit the theory, change the facts" > Albert Einstein He never said that. <https://en.wikiquote.org/wiki/Albert_Einstein#Misattributed> >> If you think past 99.99999 percent of light speed, it's "Anti-Semitism,", >> am I correct? >> >> At least Albert Einstein would say "that is Correcto" He would not. For two reasons: One, the word „Correcto“ does not exist in German. Two, contrary to hateful people like you, Einstein has never confused his zionism with his work in physics. He was smarter than that, a lot smarter than you are able to give him credit for, projecting your own inability and insecurity. >> How do you say "corrector" in a jewish campus?? What does that even mean? Were you thinking of English “co-rector”? Then it is „Korektor“ or „Co-Rektor“ (“assistant director” „stellvertretender Rektor“) in German. “corrector” (one who makes corrections) would be „Korrektor“ (in general) or (in the case of a work of literature) „Lektor“ instead. >> my german is not too guten... >> >> >> (i learned german from reading comic books) One would never have thought… >> Acktoon, acktoon...mac schnell. you kaput. dumkoff.

Your argument supports the concept that light is being transmitted by a medium occupying space.

How did you get that idea? You said that light takes 8 minute from the sun to arrive at the earth.....that means that light is being transmitted by a medium and the speed of light in that medium is 300,000 km/sec. With that speed it takes 8 minute for light from the sun to arrive at the earth.

About 8 minutes [∆t = (1 AU)∕c₀], yes. > that means that light is being transmitted by a medium No. See also <https://en.wikipedia.org/wiki/Light> (*all* of it). > and the speed of light in that medium is 300,000 km/sec. The speed of light in vacuum is c₀ = 299'792'458 m∕s. You can either say that the vacuum is the medium through which (_not_: by which) light is transmitted, or as vacuum is defined as “space void of matter” (QFTs notwithstanding), that there is no medium. It is usually generally stated that the transmission of light, and electromagnetic radiation in general, does not require a medium. In the case of the Sun it makes sense to consider the interplanetary medium, because that is not a perfect vacuum, and so the speed of light in that medium is less than c₀. But that is not a medium that allows, but one that *hinders* (slightly, given the miniscule number of particles and their kinetic energies) the transmission of light. > With that speed it takes 8 minute for light from the sun to arrive at the > earth. The travel time would be about the same in a perfect vacuum, i.e. with no other (real) particles in-between. -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail.

Such a nonsense, it is not even wrong. Instead: By 1983, measurements of the speed of light in vacuum had become so precise that, whereas in the International System of Units (SI) previously the speed of light in vacuum had been based on the meter, with the meter defined based on the wavelength of a specific emission line, it is now the other way around: the meter is defined as 1∕299'792'458 of the distance that light travels in vacuum in 1 second. <https://en.wikipedia.org/wiki/Speed_of_light> <https://en.wikipedia.org/wiki/Metre#Wavelength_definition> >> You can either say that the vacuum is the medium through which (_not_: by >> which) light is transmitted, or as vacuum is defined as “space void of >> matter” (QFTs notwithstanding), that there is no medium.

And pears are growing on a willow. The willow is defined this way - I can write this definition whenever you want, poor idiot.

Unfortunately, you only imagined this contrast:( Your pathetic attempts of defining have the same disadvantage. And my definition of willow will at least be consistent. By contrast.
