    We know today that witnesses were paid not to say that the boat had broken
    in two.

    Which still poses a problem.

    Why not confess, and why pay people if, the boat having hit a huge iceberg
    the size of the island of Corsica, began to sink, and finally broke in two (which explorations have found)?

    Why keep silent that the boat broke in two?

    Because it broke from the start, and not like in the movie (where the two pieces flow together at the end).

    The front part sinking immediately (numerous testimonies, there are even precise times) the bulk of the boat drifting over several hundred meters
    and sinking further and later.

    No need for an iceberg for that.

    The boat did all of this on its own.

    You see, my sweet darling, you are intelligent, and you know your lessons
    well.

    Me, I'm stupid and conspiratorial.

    Well, first you can refer to boats, in English, by "she", not "he".

    Moreover you clearly don't know what "fart" means in English.

    We know today that witnesses were paid not to say that the boat had
    broken in two.

    Oh, really? We "know"? Do you have any source for that?

    You are right.
    But I think that they were trying to describe actual situation:
    1. Clocks A and B are in relative motion.
    2. A is accumulating clock seconds slower than B.
    3. A is accumulating clock seconds faster than B.
    4. But they don't know which of the above is the actual true.
    5. So they cover both possibilities and knowing that only one of the statement is true.
    Not even wrong. Gobbledygook.

    I think that you don't know what relativity is saying. So you just give your bullshit.
    Read that post I referred to above. Relativity definitely does NOT say
    that "each clock is slower than the other", which is obvious nonsense. Relativity would not have survived (would not have been accepted

    5. So they cover both possibilities and knowing that only one of the statement is true.
    6. Checkout my theory IRT. Each clock has two possibilities:A predicts that B is accumulating clock seconds slower or faster than A. and B is accumulating clock second faster than A. Only one of these predictions is correct. My theory is called IRT
    and IRT is described fully in my book:
    Model Mechanics: The Final Theory

    Unfortunately Microsoft blocked my book on line. Amazon posted my book (in pdf form) online in their site with the following link:

    You need to improve your logic skills. This does not follow at
    all.

    What it really means is that in terms of one clock's coordinates,
    the other clock has decreasing "time dilation" as they come back
    together with decreasing relative velocity. Once they are back
    together they have zero relative velocity and identical clock tick
    rates.

    Note: this says nothing about the elapsed proper times of the two
    clocks -- that is related to their two paths through spacetime, and
    not merely their relative velocity.

    Tom Roberts

    Hi Tom,

    when velocity decreased in outgoing direction, time dilation would
    decrease too.

    Yes.

    when the clock move back. there is different story.

    No. It's just that YOU do not understand this.

    When the traveling twin (other clock) comes back, the velocity
    becomes negative, the other clock would experience time contraction
    instead of time dilation.

    No! Because "time dilation" depends on the square of relative velocity
    (i.e. v.v when v is the 3-vector velocity relative to an inertial
    frame). It is relative SPEED that matters, and the sign of the relative velocity is irrelevant.

    I described this situation in detail in
    chapter 7 of my book Absolute time.

    Then it's wrong and not worth reading.

    Velocity without a reference frame does not make any sense. If you mean velocity relative to all other frames of reference, that also does not
    make sense.

    So a spaceship travelling at 0.5c will be travelling at 0.5c as measured in all frames of reference?

    Yes.
    The traveling twin experiences acceleration at the turnaround.
    The stay-at-home twin does not experience the acceleration.
    The situation is not symmetric.

    It can be calculated as well.

    What I mean is, is there some sort of space time navigation device like a GPS that could show the person on board
    where he is in this space time and what sensors would it use to obtain its data from?
    I would think all that is needed is a clock measuring proper time of the traveler and an accelerometer. And computing power to keep track of everything, so if there is zero acceleration for a year, you know that
    you were moving at a certain constant speed for a year, but need past history to compute what the speed (relative to the start) would be.

    What would the accelerators show? Everything on the spaceship is taking place as normal, in a Newtonian universe.
    So he burns the fuel and accelerates. Then he burns more fuel and accelerates and so on. He continues accelerating
    past c.

    Or is it that his undetected mass increase is now incrementally limiting his acceleration? What does the fuel gauge show?
    What does he see looking out the window?

    "NARRATOR: If we could experience the world the way a ray of light does, the world would look completely different. At near light speed, we'd hardly recognize familiar surroundings. Likewise, the Doppler effect would make objects so bright, we couldn't

    Speed of light relative to what?


    You could simple run a projection from accelerometers but during a coasting stage, the stage where the spaceship is moving
    with constant velocity, is there anything that will inform the person on board that he is taking a particular path.
    Past history of all accelerations and times.

    Basically, can a navigation system for spacetime be created, in theory?

    I thought he meant it just for light only. Thus addition of velocities becomes completely meaningless as the velocities between two relatively moving objects in two frames of reference becomes a significant fraction of light.

    I do not accept the concept of the velocity of something with respect to nothing as a meaningful concept. It is like using the wave equation
    for sound waves or water waves and then applying it to empty space.

    This is not a problem of understanding, it is a question of how one is prepared to view the universe.

    If you can understand the concept, it is about empty space (nothing) expanding and stretching. Of course you can say that that is all
    a mathematical construct that gives the right answers, of course, that is what I am saying.

    Einstein in his later years came to describe that the Aether existed. I do not claim to understand, just to add to the confusion here:

    That's right. You have to use the SR speed combination formula, not
    simple addition for relativistic speeds.

    For two rockets going at 0.5c will see each other moving at 0.8c (not 1.0c).

    It's not "relative to nothing". The speed of light is c relative to
    EVERYTHING (inertial).

    No, it is a problem of your understanding.

    Non.

    Je ne cesse de le dire, vous confondez bathmotropie (chronotropie) et
    temps mesurés réciproques.

    Pendant le voyage de B pour A, il va se passer un temps pour B et un temps
    pour A.

    Et pendant le voyage de A pour B, il va se passer un temps pour A et un
    temps pour B.

    Et, évidement, sinon c'est de la plus haute absurdité, les temps noté
    pour A et B, lors de leur conjonction final seront cohérent.

    Par exemple, les deux s'accorderont pour dire que A a vieilli de 30 ans,
    et B a vieilli de 18 ans.

    C'est ce qu'on appelle les temps mesurés réciproques.

    MAIS, je ne cesse de le dire, il ne faut pas confondre ça, avec la chronotropie réciproque.

    La chronotropie réciproque, c'est le fait que, toujours, du fait de leur vitesse relative, les deux protagonistes ont des systèmes de mesure
    interne du temps qui battent plus vite que la montre opposée.

    Ce n'est pas contradictoire.

    C'est juste que les physiciens (qu'ils soient expert ou novices) ne
    comprennent pas que nosu parlons ici de deux choses différentes.

    Toujours, toujours, toujours, dans n'importe quel endroit et à n'importe
    quel moment de leur évolution,
    les deux montres ont eu des chronotropies réciproques propres positives ; elles ont battu plus vite que l'autre.

    Mais chose étonnante, et si l'on ne comprend pas l'anisochronie
    d'Hachel, on se demande comment cela est possible dans ce cas, que l'un
    revient âgé de 18 ans, et l'autre âgé de 30ans.

    On ne comprends pas le génie du raisonnement.

    Ni les cranks, qui, ne pensant qu'à leur ventre, ne m'épaulent pas.

    Ni les grands pontes de la physique, qui surclassés sur la théorie,

    Oh is that the game we are playing? Subtle trickery?

    The intial arguments for SRT rely on Newtonian Mechanics and Galilean Relativity, which Einstein calls
    the 'Principle of Relativity'. He does make the claim that the present (in 1905, pre-Relativity)
    methods of understanding time and measurement may be suspect, but that is a claim.

    The problem with the paper is clarity. There is no mention of how closing velocity is different
    from relative velocity, which every schoolboy knows if he has done Mathematics. There is
    no discussion of real-time effects as opposed to recorded events. I am not sure it will be understood

    To ANY frame of reference, imbecile.

    Velocity without a reference frame does not make any sense. If you mean velocity relative to all other frames of reference, that also does not
    make sense.

    So a spaceship travelling at 0.5c will be travelling at 0.5c as measured in all frames of reference?

    No. In other frames of reference it can be moving at any speed up to,
    but not including, c.

    Stopping the train and getting out involves choosing an inertial frame

    Why choose the center of radiation of the light to be the endpoints of M instead of M'?

    Each observer will see the end of the train and light emanating from that spot. Moving sources are equivalent to non moving sources if the second postulate is true. If the light from the source is seen by both M and M' then it is not moving with
    respect to each.

    Why choose the center of radiation of the light to be the endpoints of M instead of M'?

    The centers of radiation are where/when the bars strike each
    other to create sparks. So the centers of radiation are the
    endpoints of *BOTH*. View the animation again. You are
    misinterpreting what you see.

    Each observer will see the end of the train and light emanating from that spot. Moving sources are equivalent to non moving sources if the second postulate is true. If the light from the source is seen by both M and M' then it is not moving with
    respect to each.

    Why cant anyone see this?

    No one ever claimed that relativity was easy to understand. It is clearly not in the least intuative.

    There is no substitute for study.

    Autant je comprends parfaitement qu'on PEUT synchroniser deux montres qui
    se trouvent au même endroit,
    quelque soit leur référentiel inertiel (donc au moment de leur

    Paris avec une autre qui se trouve à Moscou est particulièrement
    stupide.

    C'est absurde.

    C'est montrer qu'on n'a rien compris de la relativité et qu'on conçoit
    le monde comme le concevait monsieur Einstein et monsieur Minkowski.

    Autant on peut synchroniser des montres évoluant dans des milliers de référentiels inertiels différents,
    pour peu qu'on les règle au moment de leur conjonction, autant on ne
    pourra jamais régler absolument des milliers de montres entre elles, si
    elle se trouvent dans le même référentiel, mais en des endroits
    différents.

    Cette histoire de "vitesse de la lumière" égale à l'aller comme au
    retour montre une incompréhension totale de la notion d'anisochronie
    spatiale.

    Alors évidemment, si on dit "oui, mais ça n'existe pas; Hachel se
    trompe, il n'y a pas d'anisochronie"...

    Dans ce cas là on peut faire ce qu'on veut et dire que cinq joint à

    The syncnronization described in the 1905 paper is better characterised as initial synchronization, or initialized. It cannot mean synchronized
    in the sense of running in lockstep with each other.

    A series of back and forth signals would have to take place to establish

    I don't think I have any real difficulty with understanding things
    clearly.

    On the other hand, and here we expose ourselves to an immense human
    problem which is the understanding of things by the scientific elite.

    I repeat, the scientific elite do not understand the theory of relativity,
    the Christian elite the religion of Jesus Christ, the political elite how
    to run a nation.

    The misunderstandings are huge and those who discover them to others
    thrown to the lions.

    That's how the world works.

    For the theory of relativity, if, for example, an intelligent
    extraterrestrial species visited us, they would be taken with immense astonishment.

    They would say: "It's just incredible, they have understood the most
    difficult part (the relativity of chronotropy by change of reference
    frame) and their gamma factor is correct; but are unable to understand the simple notion of anisotropy, and they believe again to the notion of
    "plane of present time in a given inertial frame".

    I think their astonishment would be very great.

    You keep making it into some sort of personal issue.

    Not even wrong. This is NOT what relativity is saying.
    Just stop and think for one second: if relativity in fact did

    already in early December 1905. What are you thinking, that everyone is an idiot?
    No. Just you...
    The paradox has always been a real contradiction.
    There is no contradiction there. You make an incorrect assumption along the way and, unsurprisingly, come
    up with an error. But it's your wrong assumption(*) that's
    the problem, not relativity.

    (*)You assume that the same set of clocks participates
    in the time dilation comparison. Obviously, if you make
    that FALSE assumption, you get nonsense: the same clock
    must be running both faster and slower than some other
    clock. But this is NOT how the time dilation works in relativity. You really ought to study this theory in more detail. Until you do that, you'll be forever haunted by
    such mirages in the desert.
    Comparing two clocks the following possibilities exist:
    1. A accumulates clock seconds at a faster rate than B
    2. A accumulates clock seconds at a slower rate than B.
    3. A and B accumulate clock seconds at the same rate.

    Do you see Einstein's nonsense that:
    A sees B accumulating clock seconds at a slower rate than A.
    B sees A accumulating clock seconds at a slower rate than B. ???????????
    Except this is not what Einstein says.
    Why are you refusing to give us what Einstein is really saying.

    Your summary above is stating something very different than
    what relativity says.
    This has been posted on this NG countless times over the years but
    here is a recent iteration: https://groups.google.com/g/sci.physics.relativity/c/quhr5NzrTio/m/bzzqG9rWBAAJ
    So give us the real statement what relativity is saying.
    I think that you don't know what relativity is saying. So you just give your bullshit.
    Read that post I referred to above. Relativity definitely does NOT say that "each clock is slower than the other", which is obvious nonsense. Relativity would not have survived (would not have been accepted
    for publication even) if it claimed any siuch ludicrous thing.

    I did not say that "each clock is slower is slower than the other."
    I said that A predicts that B is running slower than A.
    and that and that B predicts that A is running slower than B.
    Not that it's running slower but comparing certain clocks and
    calculating yields that result. It's about certain rates measured
    *at a distance*.

    There is no contradiction in that, it's like that example of two roads
    I gave: the key point is that until A and B turn around, all they are
    doing is calculating time rates at a distance using their (distant)
    clocks.

    When comparing two clocks in relative motion:
    1. A predicts that B is accumulating clock seconds at a raster rate than B.
    2. B predicts that A is accumulating clock seconds at a faster rate rate than A.
    3. Only one pdf the above predictions is correct.

    What is the bathmotropy of a human heart?

    It's his excitability.

    For example, if you consume a lot of coffee, it is possible that the bathmotropia of your heart is greater.

    It is a medical term, of course, but I do not see why physicists could
    not, too, use this term.

    When doctors measure someone's height, they use meters.

    They say "this man is 1.78m tall."

    Physicists use the same notion, they say: "This particle traveled 253m."

    Doctors and physicists can thus agree on a concept, and use the same term.

    In physics, the bathmotropy of watches is their reciprocal excitability.

    If the bathmotropy is more important, the chronotropy is more important.

    If a heart is more excitable, it beats faster.

    Chronotropy and bathmotropy MUST enter the vocabulary of relativistic physicists.

    It's still not the ocean to drink that we ask them.

    When two watches are in motion with respect to each other, there will
    exist in relativity, a strange phenomenon which makes their reciprocal bathmotropy seem to decrease.

    Each of the watches considers that the other has a less excitable, less efficient mechanism.

    This is the notion of reciprocal negative bathmotropy.

    This is a universal internal mechanism.

    But that is not all.

    In addition, another phenomenon will occur which is linked to spatial anisochrony (the fact that absolute simultaneity does not exist for two entities, even fixed ones, which are not in the same place), and the time measured by one watch compared to another will therefore be doubly
    disturbed.

    The formula for comparing the times measured will therefore be, in total: t=t₀.(1+cosµ.v/c)/sqrt(1-v²/c²)

    The numerator being a factor of the anisochrony crossed, the denominator
    being linked to the reciprocal chronotropy (how time is measured in
    relation to the other frame of reference).

    I see, thank you, it is a sort of relative ticking rate:

    Bathmotropic often refers to modifying the degree of excitability specifically of the heart; in general, it refers to modification of the degree of excitability (threshold of excitation) of musculature in general, including the heart.

    Is light speed absolute?
    If so does it not wave in time
    and is that not its absolute

    Mitch never provides references. He pulls his "facts" from his butt,

    Velocity consists of speed and direction, or distance divided by time in a particular direction.

    Speed is simply the distance divided by time regardless of direction...

    Velocity is actually displacement, that is, the change in coordinates relative to a specified starting point, divided by
    the time taken. Displacement has to be specified in terms of coordinates in three dimensions.

    Let us see what Wikipedia says:

    "Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound). Velocity is a
    fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies."

    Yes so why use speed? Because it is the same everywhere like McDonalds.?

    Why not define light velocity differently ?

    Light from the sun consists of photons emitted in all directions.

    It is interesting that Einstein used the term velocity of light:

    "namely, that light is always propagated in empty
    space with a definite velocity c which is independent of the state of motion of the
    emitting body."

    So he had in mind a narrow beam of light or ray of light, which could be defined as

    "Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound). Velocity is a

    I suppose we have to work these two out to everyones satisfaction, which is not maybe possible here.

    That is a problem of the translation from German to English.

    Right so let me tell you how I would be comfortable defining it.

    The velocity of an object is defined with refence to a coordinate system and time.
    If the displacement of an object from position x1, y1, z1 in thatcoordinate system to position
    x2, y2, z2 in that same coordinate system is s, then the velocity of the object is s/t where
    t is the time taken for this displacement. The direction of movement must also be specified.

    The direction of this movement can be calculated from the coordinates, but in some cases, like in Earth- based navigation, is defined as the angle the path of the object makes with the navigational compass; for example, bearing 060, for
    aircraft tracking.

    The Sun is assumed to emit its light through an immeasurable number of photons. These photons are assumed to travel equally fast in each direction after leaving
    the surface of the Sun, or after the point relative to the Sun where they are in free space. The numerical value of the velocity of each photon is called
    the speed of the photon. It is in this context that it is stated that the
    speed of light emitted from the Sun is c, in all directions.

    As usual, one has to be very careful with definitions here.

    ChatGPT. Did they waste their money?

    Question:
    What are the valid deductions from the statements, in formal logical notation, for the following statements: two clocks are moving relative to each other, and movement of one clock relative to another causes a clock to runs slower than the other?

    Answer:
    Let's symbolize the statements using propositional logic:

    P: Two clocks are moving relative to each other.
    Q: Movement of one clock relative to another causes a clock to run slower than the other.

    We can then translate the statements into logical notation as:

    P: C1 is moving relative to C2, or C2 is moving relative to C1.
    Q: If C1 is moving relative to C2, then C1 runs slower than C2, or if C2 is moving relative to C1, then C2 runs slower than C1.

    From these statements, we can deduce the following:

    If C1 is not moving relative to C2, then neither C1 nor C2 runs slower than the other. (Contrapositive of Q)
    If C1 runs slower than C2, then C1 is moving relative to C2. (Converse of Q)
    If C2 runs slower than C1, then C2 is moving relative to C1. (Converse of Q)
    If C1 and C2 are both stationary, then neither clock runs slower than the other. (From P and Q)
    Note that these deductions are based on the assumptions implicit in the given statements, such as the clocks being identical, and the relative motion being constant and uniform. In reality, the situation may be more complex and additional factors may
    need to be considered.

    Question:
    Is the statement C1 is running slower than C2 and C2 is running slower than C1 a contradiction according to the above statements, if C1 and C2 are moving relative to each other?

    Answer:
    Yes, the statement "C1 is running slower than C2 and C2 is running slower than C1" is a contradiction according to the given statements.

    Assuming that C1 and C2 are moving relative to each other, the statement "C1 is running slower than C2" is equivalent to the statement "movement of C2 relative to C1 causes C1 to run slower than C2" (using the logical notation we established earlier).
    Similarly, the statement "C2 is running slower than C1" is equivalent to the statement "movement of C1 relative to C2 causes C2 to run slower than C1".

    These two statements together would imply that both C1 and C2 are simultaneously running slower than each other, which is a contradiction. Therefore, if C1 and C2 are moving relative to each other, the statement "C1 is running slower than C2 and C2 is
    running slower than C1" cannot be true.
