    The speed at which light waves propagate in vacuum is independent both of the motion of the wave source and of the inertial frame of reference of the observer.[Note 6] This invariance of the speed of light was postulated by Einstein in 1905,[8] after
    being motivated by Maxwell's theory of electromagnetism and the lack of evidence for the luminiferous aether;[19] it has since been consistently confirmed by many experiments.[Note 7]

    Come, Gehan. You can only wait four hours before deciding there is no
    "proof"? First of all, this is a question of physics, not mathematics. Mathematicians deal with proofs, physicists either confirm or refute by experimental evidence.

    And there is considerable experimental evidence:

    https://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html#one-way_tests

    This should be enough to keep you busy for a long time :-)

    I particularly like Lunar Laser Ranging Experiments. One thing not mentioned in the link is communication with spacecraft moving at up to 50 km/sec around Saturn and beyond. At such distances and speeds, any dependence of the speed of light on the motions between transmitters and receivers would be quite obvious.

    "The theory of relativity is considered to be self-consistent, is consistent with many experimental results, and serves as the basis of many successful theories like quantum electrodynamics. Therefore, fundamental criticism (like that of Herbert Dingle,
    Louis Essen, Petr Beckmann, Maurice Allais and Tom van Flandern) has not been taken seriously by the scientific community, and due to the lack of quality of many critical publications (found in the process of peer review) they were rarely accepted for
    publication in reputable scientific journals. -Wikipedia"

    You personally expect me to go through and peer review hundreds of experiments that have been done in conditions I
    cannot ever hope to achieve? Or go through their papers and find errors in them? I think a more practical approach would be
    to simply tell me I can never understand Special Relativity so give it up.

    Or accept the theory based on Authority, though I cannot see how the second postulate could be valid.

    Some of the experiments you listed search for Aether, and since no Aether is found, this means SRT is true.
    Is this the route you want to go?

    also find an inconsistency in large areas of mathematics. Hopeless.
    Certainly the fools and idiots around here have no hope of doing so.

    Whether SR accurately models the world we inhabit is a VERY different
    question, one that requires experiments, not math. To date nobody has

    I am assuming that no valid criticism can be made of the assumption that 'light
    travels at velocity c in all inertial frames of reference' even though these frames
    of reference are that hold stationary object that are moving relative to each
    other.

    My personal opinion is that this will lead to logical contradictions, however,
    if no examples can be offered, we can consider this closed.

    The problem is that many of the member of this forum seem to think otherwise, in
    which case a simple, easy to understand proof will settle the issue.

    Opinion of these "members" are pointless.

    Relativity is mathematically identical to hyperbolic 4-D geometry which
    is known (i.e. there is a proof of that) to be para-consistent with
    Euclidean Geometry.

    Don't hold you breath waiting for a logical contradiction to be
    found in SR... There is provably *none*.

    J'ai ri.

    Post your proof here.

    First, there are no inconsistencies due to the speed of light.

    Light (electromagnetic radiation) is how we are informed of astronomic events. Therefore, light is a signal carrying the information of the occurrence of remote events.

    The maximum speed of propagation of interactions (events) is c. Its existence implies that motions of bodies with greater speed than light are impossible in Nature, since if so, the occurrence of an event would be known before the event occurred.

    A "vacuum" does not exist.


    Sinces yous peoples don'ts understands...

    Here is the definition of "vacuum":


    a space entirely devoid of matter.
    synonyms: empty space, emptiness, void, nothingness, vacuity, vacancy, voidness, nihility

    https://www.google.com/search?hl=en&source=hp&biw=&bih=&q=define+vacuum


    Now, show me where is this 'space entirely devoid of matter' located at?

    prove that this invariance of the speed of light leads to logical inconsistencies

    For something that is logically consistent, it isn't possible to give a valid proof that it is logically inconsistent. When grown-ups say the speed of light is invariant, they mean the speed of light (in vacuum) has the same value in terms of every
    standard system of inertial coordinates, which are related by Lorentz transformations because energy E has inertia E/c^2. This is easily shown:

    If light propagates at speed 1 (in suitable units) in terms of coordinates x,t, this means dx/dt = 1 for any increment along the trajectory of the pulse, and another standard inertial coordinate system x',t' moving at speed v relative to the first is
    related by x'=(x-vt)g, t'=(t-vx)g where g=1/sqrt(1-v^2). The speed of the pulse in terms of x',t' is dx'/dt' = (dx-vdt)/(dt-vdx), and dividing numerator and denominator by dt gives dx'/dt' = (1-v)/(1-v) = 1.

    Now, you may object that x',t' is not a standartd inertial coordinate system, and that we should really use the coordinates x"=x-vt, t"=t, meaning the Galilean transformation. However, we can test whether the standard inertial coordinates moving at
    speed v relative to x,t agree with x',t', or with x", t", and we invariably find that they agree with x',t'. In other words, as a matter of empirical fact, standard inertial coordinate systems are related by Lorentz transformations, not by Galilean
    transformations. The laws of physics take their simple homogeneous and isotropic form in terms of x',t', but not in terms of x",t". So, the speed of light really is 1 in terms of every standard system of inertial coordinates, and your denial of this is
    baseless. Agreed?
