    The Alice and Bob example of the FTL violates causality

    Does anyone know (and can give a link) if there's an animation of Richard Baker's diagrams? An animation of the explanation?

    The Alice and Bob example of the FTL violates causality

    Yes, and yet, something in the explanation still bothers me: Since every participant has speed, their position changes with time. Even if everyone was "stationary", space still moves around them, meaning, their position still changes with time. But you know what, let's stick exactly to the...

    The Alice and Bob example of the FTL violates causality

    Look at Figure 5 in Richard's explanation: http://www.theculture.org/rich/sharpblue/archives/000089.html Say Alice has an FTL comm connection to Dave, and she calls him and say "Hi Dave, I'm in front of planet Zoton (P), you should see the view!" Dave answers in his FTL comm: "What are you...

    The Alice and Bob example of the FTL violates causality

    Hmmmm. I'm trying to make the order of events of the experiment you suggested: 1) Alice starts at R (say it's some big rock floating in space). 2) Alice accelerates to planet Zoton (P) (not instantly, you didn't say instantly, so it took her time, say a few hours) from the rock R, which...

    The Alice and Bob example of the FTL violates causality

    Weird, I thought that understanding order of events (inc' simultaneity) was one of the main reasons that motivated Einstein to form his theory. At least from what I read about it (I think I read it here: http://www.einstein-online.info/home-eo?set_language=en ). But OK, I think I'm starting to...

    The Alice and Bob example of the FTL violates causality

    1) Since everyone in the example uses instant massaging, the whole thing took less than, say 20 seconds max, and the distance between P, Q, and R, although not mentioned, is probably (and let's say it is) in the billions of kilometers. And the whole mess began only after Alice (after a very long...

    The Alice and Bob example of the FTL violates causality

    As many, I wondered why FTL communication has problems with causality. Went over many posts here in PF, and wasn't satisfied. And then I read this explanation, by Richard Baker: (2015-4-2, link is still active) http://www.theculture.org/rich/sharpblue/archives/000089.html His explanation is a...
