Speed of Light Relative to a Moving Observer

"Doppler effect - when an observer moves away from a stationary source. Pay attention to the velocity of the wave relative to the observer. When an observer moves away from a stationary source, the period of the wave emitted by a source is longer and the observed frequency is lower. Because the velocity of the wave relative to the observer is slower than that when it is still."

The variation of the speed of the wave (relative to the observer) with the speed of the observer holds for all kinds of waves and is fatal for special relativity. For the sake of argument, let us assume that the above video concerns only sound waves while for light waves the picture is different. Is it? No, the picture for light waves is exactly the same:

Dr Ricardo Eusebi: "f'=f(1+v/c). Light frequency is relative to the observer. The velocity is not though. The velocity is the same in all the reference frames."

Note however that Dr Ricardo Eusebi does not see the variation of the speed of the wave with the speed of the observer. Why? Because in Divine Albert's world the old principle of Ignatius of Loyola is valid and Dr Ricardo Eusebi obeys it:

Ignatius of Loyola: "That we may be altogether of the same mind and in conformity with the Church herself, if she shall have defined anything to be black which appears to our eyes to be white, we ought in like manner to pronounce it to be black."

    The Fundamental Equation of Special Relativity

    "Doppler effect - when an observer moves away from a stationary source. Pay attention to the velocity of the wave relative to the observer. When an observer moves away from a stationary source, the period of the wave emitted by a source is longer and the observed frequency is lower. Because the velocity of the wave relative to the observer is slower than that when it is still."

    The observer starts moving away from the light source with speed v. The frequency he measures shifts from f=c/d to f'=(c-v)/d, where d is the distance between the pulses. (If v is small enough, the formula f'=(c-v)/d is virtually exact no matter whether the classical or relativistic Doppler effect is considered.)

    The speed of the pulses relative to the moving observer is:

    c' = d*f' = c - v = c

    where c - v = c is the fundamental equation of special relativity.

    Considering that General relativity also predicts that clocks in different gravitational fields can run at different rates;

    And whereas, given the signal retardation by solar gravity, it has been demonstrated that this time dilation predicted by general relativity also applies to light transit time over a given distance and not just the frequency of atomic clocks alone;

    May I propose that using the same instrumental set-up that established light velocity value over a distance as 299792458m/s, that the velocity of light be measured in the flatter and freer space-times in space to find out if Einstein's statement is vindicated, page 903, "From the proposition which has just been proved, that the velocity of light in the gravitational field is a function of the location,...".

      The Metamorphisis of the Ideal Gas Law into CIG Theory's MTS Equation - a New Interpretation (adulteration!) of the Ideal Gas Law

      From Wiki:

      The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation to the behaviour of many gases under many conditions, although it has several limitations. It was first stated by Émile Clapeyron in 1834 as a combination of Boyle's law and Charles' law. The ideal gas law is often introduced in its common form:

      PV=nRT,

      where P is the absolute pressure of the gas, V is the volume of the gas, n is the amount of substance of gas (measured in moles), T is the absolute temperature of the gas and R is the ideal, or universal, gas constant.

      END Wiki

      From CIG Theory:

      MTS where: M = matter (and its presence resulting from the curvature of spacetime - the S/T portion of the equation using vector Time), T = forward reverse vector Time and based on %c, and S = Space itself though at various field densities (again, equivalent as M using the equation - with the extreme being pur vacuum energy)

      SEE ALL PRIOR POSTS

      METAMORPHISIS

      Let T (from Ideal Gas Law) = temperature = movement of the particles = % "c" = Time in the MTS equation (recall that T in CIG Theory = %"c"

      Let V = Volume (from Ideal Gas Law) = S (in CIG Theory) = Space = the new and various spatial volumes (in their respective field) created as a result of mass traveling at various rates (temperatures)

      Let P = Pressure (from the ideal Gas Law) = it disappears in the MTS Cig Theory = because the is no constraint within CIG Theory (no outer boundary that restricts the vessel walls)

      Let n = the amount of substance of gas (measured in moles)(from ideal Gas Law) = M = Matter in CIG Theory = the actual mass/matter/substance that has weight (is actually there)

      Enter Wiki Again:

      The gas constant (also known as the molar, universal, or ideal gas constant, denoted by the symbol R or R) is a physical constant which is featured in many fundamental equations in the physical sciences, such as the ideal gas law and the Nernst equation.

      It is equivalent to the Boltzmann constant, but expressed in units of energy (i.e. the pressure-volume product) per temperature increment per mole (rather than energy per temperature increment per particle). The constant is also a combination of the constants from Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law.

      Physically, the gas constant is the constant of proportionality that happens to relate the energy scale in physics to the temperature scale, when a mole of particles at the stated temperature is being considered. Thus, the value of the gas constant ultimately derives from historical decisions and accidents in the setting of the energy and temperature scales, plus similar historical setting of the value of the molar scale used for the counting of particles. The last factor is not a consideration in the value of the Boltzmann constant, which does a similar job of equating linear energy and temperature scales.

      END Wiki: because I didn't really understand what is happening (i.e.the gas constant ultimately derives from historical decisions and accidents in the setting of the energy and temperature scales, plus similar historical setting of the value of the molar scale used for the counting of particles.)

      REPEAT of the above:

      METAMORPHISIS

      Let T (from Ideal Gas Law) = temperature = movement of the particles = % "c" = Time in the MTS equation (recall that T in CIG Theory = %"c"

      Let V = Volume (from Ideal Gas Law) = S (in CIG Theory) = Space = the new and various spatial volumes (in their respective field) created as a result of mass traveling at various rates (temperatures)

      Let P = Pressure (from the ideal Gas Law) = it disappears in the MTS Cig Theory = because the is no constraint within CIG Theory (no outer boundary that restricts the vessel walls)

      Let n = the amount of substance of gas (measured in moles)(from ideal Gas Law) = M = Matter in CIG Theory = the actual mass/matter/substance that has weight (is actually there)

      Let R = the ideal, or universal, gas constant (from ideal Gas Law) = some type of historical correction factor = no known counterpart in CIG Theory = IGNORE "R"

      SUBSTITUTION:

      V = S

      n = M

      T = T

      V = nT (new ideal gas law as morphed by CIG and as explained above)

      S = MT CIG Theory)

      or, MT = S in the forward (arbitrary direction of time) [in one post, using Biblical from darkness, the world was created stuff, I believe I selected 100 %"c" to zero % "c" as forward vector time]

      [Recall that MTS uses both forward and reverse vector time]

      cigtheory.com however still uses MT=S

      so, nT = V has morphed into MT = S

      In both equations, when rate goes up (temperature), volume (space) has been created.

      In MTS, since it involves rates of travel from zero to "c", spacetime curvatures become apparent.

      and enter CIG's explanation of Dark matter and Dark Energy, Double Slit, etc. and the community should look close at the theory.

      Let CIG Theory = Butterfly

      The below is to supplement the above post regarding the metamorphosis of the Ideal Gas Law into CIG Theory's MTS equation. While the below is a repeat of a post I placed on the "Faster than Light" article, nonetheless it should appear here to be taken in context with the Metamorphosis, and, based on substitution, the Ideal Gas law can now be substituted into Einstein's field equation as follows (Very important - this substitution only to taken within the extent I have correlated CIG Theory to both):

      Let A = Einstein's field equation

      Let B = Ideal Gas Law

      Let C = CIG Theory

      The below re-post correlates A = C

      My Metamorphosis post this day earlier and above correlates C = B

      So, by substitution A = B

      Hey, my math isn't that bad after all !

      Therefore:

      A = Einstein's field equation = B = Ideal Gas Law = C = CIG Theory

      The below as re-posted:

      OK - I'll save you the trouble of asking, and here are my "ramblings" about the link of CIG to Einstein field equations that I referenced above. I don't understand the field equations, but looked at them closely enough to compare certain variables in the quation. Please focus on those variables. So, what I stated in the above post is that CIG can be found within the Eistein field equation, according to a new INTERPRETATION. I've explained it below as best I can:

      From the Wiki - Cosmological Constant site:

      The cosmological constant Λ appears in Einstein's modified field equation in the form of

      ADD Field Equation Here as it would not "cut and paste" see Wiki

      where R and g pertain to the structure of spacetime, T pertains to matter and energy (thought of as affecting that structure), and G and c are conversion factors that arise from using traditional units of measurement. When Λ is zero, this reduces to the original field equation of general relativity. When T is zero, the field equation describes empty space (the vacuum).

      The cosmological constant has the same effect as an intrinsic energy density of the vacuum, ρvac (and an associated pressure). In this context it is commonly defined with a proportionality factor of 8π: Λ = 8πρvac, where unit conventions of general relativity are used (otherwise factors of G and c would also appear). It is common to quote values of energy density directly, though still using the name "cosmological constant".

      A positive vacuum energy density resulting from a cosmological constant implies a negative pressure, and vice versa. If the energy density is positive, the associated negative pressure will drive an accelerated expansion of empty space. (See dark energy and cosmic inflation for details.)

      END Wiki

      Enter CIG

      OK - Specifically, where it is stated above, "When T is zero, the field equation describes empty space (the vacuum). & remember, " T pertains to matter and energy (thought of as affecting that structure)"

      this correlates with CIG as follows:

      In CIG, when matter [their T (not mine which states T=Time)] is no longer there, it has transformed into space [MT=S]. It is an interpretation that within the Einstein equation, and where T pertains to matter and energy (thought of as affecting that structure, and where it is also stated that When T is zero, the field equation describes empty space (the vacuum), this all correlates to CIG, whereby it is an active process through which matter manifests itself into the vaccuum. It is stated many times within CIG that this is due to varying rates (% of"c"). Spacetime must be broken.

      While CIG offers that the new matter is NOT continuously created as the universe expands (rather the expansion is at the expense of mass) (in this respect Fred Hoyle was off topic) and that the Universe DOES change its appearance over time :

      Nonetheless there is a steady state aspect to CIG Theory as the new Space unfolds steadily [as the mass goes down , the space (expansion) unfolds]

      CIG also looks at each traveling mass as its own "Big Bang" - unfolding over time (rate dependent)

      So, we can revisit Fred Hoyle in the context in which CIG Theory offers a new interpretation of the Steady State Theory. Steady creation of space at the expense of mass (conservation of energy)

      The theory also vindicates Einstein in that it brings back a certain sense of determinism back into the picture.

      The International Bureau of Weights and Measures says:

      "The METRE is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a SECOND.[link:www.bipm.org/en/si/si_brochure/chapter2/2-1/metre.html]It follows that the speed of light in vacuum is exactly 299 792 458 metres per second, CO = 299 792 458 m/s[/link] ".

      And,

      "The SECOND is the duration of 9 192 631 770 PERIODS of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. It follows that the hyperfine splitting in the ground state of the caesium 133 atom is exactly 9 192 631 770 hertz".

      IF gravity slows time AND PROLONGS PERIODS, clocks run faster in outer space (higher frequency) and thus the period of Caesium 133 is shorter (shorter SECOND), it will be of interest to Test Reality In Space and verify this prediction of Einstein in the International Space Station or in other Satellites, subsequently leaving us with the choice of either redefining the second or the metre and their domain of validity, or agreeing with Einstein that "the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity and to which we have already frequently referred, cannot claim any unlimited validity",page 89.

      Akinbo

      Further to my last post above. On the International Bureau of Weights and Measures' definition of a second, and the seeming agenda to foist a fait accompli on the value 299792458m/s as the speed of light in vacuum by using the adjective "exactly". In order for this conspiratorial plan to work there MUST BE a further qualification in the definition of the second by adding "at earth surface". This is because Pound and Rebka in their experiment, further corroborated by the Gravity Probe A have demonstrated that Caesium 133 atom will oscillate at a frequency higher than 9 192 631 770 Hz in the vacuum at higher altitude!

      According to results from Gravity Probe A, at 10,000km, general relativity predicts that Caesium 133 will oscillate 4.5 parts in 10-10 faster than one on the Earth.

      Indeed, given the General relativity equation

      tu = td (1 - GM/rc2),

      where the subscripts u and d stand for up and down respectively,

      an atomic oscillation that takes 1 second on earth surface will take 0.9999999993 seconds in free space, far from gravity. And since frequency is the inverse of period, Caesium 133 will oscillate at 9 192 631 776 Hz in freer space, instead of 9 192 631 770 Hz. Light velocity in free space and not earth surface would be 299792458.2087m/s.

      I therefore broadly agree with John Donoghue that once this hidden agenda is abandoned for good, "It would really change 99.9 per cent of physics research".

      What next on the agenda to foist the value 299792458m/s on us, since the definition of a second is now shown here to be incomplete?

      I have developed the Spacetime Wave theory in an attempt to set a top level description for the unification of General Relativity and Quantum theory.

      The unification of physics

      Thinking about how parts of the theory could be verified in practice I have noted your interest in the possibility of conducting entanglement tests between two fast moving satellites.

      In the Spacetime Wave theory, light travels through space as a spacetime wave and the existence of a medium for light wave propagation implies a unique frame of reference even though we cannot by current experiment detect this frame. However, entanglement effects appear to act instantaneously and this implies the need to specify a frame of reference for the instantaneous effects.

      The proposal is that the entanglement effects propagate instantaneously in the unique frame of reference of the medium of spacetime.

      It can be shown that this proposal would not violate the order of cause and effect since an observer passing close to the effect cannot go on to observe the cause since he cannot go back in time.

      However, the experiment using two fast moving satellites does have the potential to measure the unique frame of reference of the entanglement effects.

      Richard

      Eckard,

      Being an EE do you mind taking a look at this paper? I submitted it as a summary to the IEEE for an upcoming conference. Out of fear of rejection I removed all talk of light velocity from the paper.

      Regards,

      AkinboAttachment #1: CPEM_2014_Summary_Paper.pdf

      Akinbo,

      I am sure that some experts of IEEE, NIST, and other organizations are well aware of Pound and Rebka. Maybe they will nonetheless accept your abstract if there is only a limited number of those who intend participating.

      Good luck,

      Eckard

      Eckard, as an EE who I know believes so much in safety, given Einstein's statement (modified) that: "...we can regard Caesium 133 atom which is emitting spectral lines as a clock, so that the following statement will hold: Caesium 133 absorbs or emits light of a frequency which is dependent on the potential of the gravitational field in which it is situated. The frequency of Caesium 133 atom situated on the surface of Earth,9 192 631 770 Hz will be somewhat less than the frequency of Caesium 133 which is situated in free space...", p.157 and the BIPM definition of a second, what will you advice astronauts going above 10,000km into space? Remember if you are one of the engineers you can be sued knowing the theory and the corroborating experiments if an accident occurs. Will you say Einstein was responsible for the accident or BIPM? Now that commercial private space trips are coming up, if an instrument on board the spacecraft depends on the definition of a second, will you embark on the trip relying on BIPM definition alone or be a bit careful in case Einstein was right?

      THE VACUUM

      Some thoughts while I have them:

      Read (until the math came along) with interest at least part of:

      http://philsci-archive.pitt.edu/398/1/cosconstant.pdf

      The Quantum Vacuum and the

      Cosmological Constant Problem

      S.E. Rughツヂnd H. Zinkernagely

      To appear in Studies in History and Philosophy of Modern Physics

      With regard to, as extracted:

      "Following these discussions, Bludman and Ruderman (1977) [9] argue that even

      though the vacuum energy density was very large at the time of the symmetry

      breaking, it was nevertheless negligible in comparison with the thermal energy density of ultra-relativistic particles present at the time."

      END (extracted material)

      ENTER CIG THEORY (www.cigtheory.com)

      If I am interpreting the above correctly, the notation appears consistent with CIG's interpretation of nature.

      Recall that in CIG, and the MTS equation, the "S" or Space side of the equation represents rate at "c" [this correlates to the comment "....it was nevertheless negligible in comparison with the thermal energy density of ultra-relativistic particles present at the time" as noted above]

      In CIG, there is a rate dependent Variable Cosmological Non-Constant.

      MTS: M is a black hole while S is pure Space (the vacuum)

      The vacuum density on the "S" side of the equation is much less per unit area than the right side, this because of the mass to space conversion.

      The M energy and the S energy are equivalent.

      But, they need to be renormalized as to the area.

      [ i.e. is the area of the new spatial equivalence in the MTS conversion (see also CUPI quantification) some 120 orders of magnitude greater in volume than the original volume of the M side of the MTS equation??] If so, the renormalization may equate the Quantum calculation(particle or "M" assumed)of the vacuum to the Observed calculation (Spatial or "S" assumed) , thereby solving the Vacuum Catastrophe]

      So, maintaining this thought pattern, perhaps the 120 orders of magnitude problem is the result of the need for an area based renormalization to account for the much greater spatial volume at relativistic speeds. Remember, in CIG, as mass travels faster and faster, it offers itself up as new spatial quantities. Space goes up, mass goes down, energy remains conserved.

      In this manner, CIG may explain the Vacuum Catastrophe and Cosmological Non-Constant Problems.

      You must understand both CIG Theory and the Vacuum Catastrophe and Cosmological (Non-Constant) Problems and in depth to assess the above.

      Perhaps S.E. Rughツヂnd H. Zinkernagel could give it a shot in the dark (recall that CIG also offers a solution to the dark matters)

      Note added to my last post entitled THE VACUUM

      For those who may not understand CIG Theory, please recognize that the Cosmological Constant varies (hence my use of the terminology Cosmological Non-Constant) as follows:

      As the rate of a traveling massive particle increases, it manifests itself as a greater Volume (at "c" it is pure space)(at zero "c" [zero mph] it is a black hole). This greater Volume (low density)(less spacetime curvature), offers itself up as a large (small??)valued Cosmological Non-Constant.

      At slow rates of travel, spacetime curvature is denser, and the Cosmological Non-Constant is therefore smaller (larger??).

      Question to the community: Does full a curvature entity (black hole)(zero mph) require the smallest cosmological constant (I think so, because nothing has to be added to counter gravity)(the reason for its introduction by Einstein in the first place).

      The varying cosmological non-constant (CIG Theory) varies Lorentz transformationaly proportional to rate of speed, and from zero mph to "c".

      See CIG Theory & try to understand (even if I'm wrong) so that you are aware of the theory. You can always throw rotten tomatoes at the theory. But you can't throw rotten tomatoes at it until you understand what it is that is being proposed.

      To Professor Isham,

      My first posting on this article was an offer that CIG Theory is offered to the community as a Theory of Quantum Gravity (on top of all its other reckless claims).

      This was only recently realized after having absorbed your simple explanation of what Quantum Gravity is, as listened to on Closer to The Truth (you are all my heroes):

      http://www.closertotruth.com/video-profile/Paths-to-Quantum-Gravity-Christopher-Isham-/1672

      Thank you and recognize that your explanation of quantum gravity represents the extent of my education in this field. However, once explained in the simple manner presented, it became clear that the MTS equation is an equation of Quantum Gravity and that CIG Theory is a theory of quantum gravity.

      While my site posted that CIG combines the mass energy equation with the spacetime continuum, and these claims are self evident in CIG, I never really knew until your explanation that this is what Quantum Gravity is all about.

      I hope one day you understand my theory (just ignore the crazy stuff)

      Regarding previous posts:

      I think I changed my mind. With regard to the MTS equation, approaching the "S" side of the equation, that is the vacuum (pure space) side, the Cosmological Non-Constant is getting smaller. Toward the "M" side it is getting larger.

      Don't disappear into a black hole just yet! I will get around to read your theory and even if I don't agree with it I am sure I would get some fresh insights which has usually been the case after exchanges with others. For example, my exchanges with Tom, Eckard and Peter J led me to writing a new paper which I hope will be published after peer-review. Another advice is that you have not been engaging with others on their own views and see what your CIG theory better explains. Nevertheless, as the saying goes tough times don't last, tough people do. Best of luck.

      In another blog topic, Quark Stars and a New State of Matter?, Alan Lowey pointed out on Feb. 20, 2014 @ 11:37 GMT that not all clocks run faster in space, "It worth noting that pendulum clocks tick or swing more slowly at higher altitudes contrary to atomic clocks. This to me is proof that 'time' can't be thought of as running faster in a lower gravitational field, only *atomic* clocks can". This appears correct, given, T = 2ПЂ(в€љl/g) or T = 2ПЂ(в€љlr2/GM) but can still be tested in space. If confirmed, this will be in contrast to atomic clocks, e.g. Gravity Probe A: "At 10,000km above earth, general relativity predicted a clock should run 4.5 parts in 10-10 faster than one on the Earth", Gravity Probe A confirmed the prediction that gravity slows the flow of time.

      MATTERS ARISING: If pendulum clocks run slower in lesser gravity, and atomic clocks run faster, what is the implication for theoretical physics? I venture to suggest a few:

      1. Since the effect of gravity on time-keeping devices NOW depends on the device, time is independent of gravity and the measurement of its flow depends on the device used.

      2. Observed slowing and bending of light IS NOT due to gravity itself directly but is mediated by and is due to something else involved in light propagation, which something else can be affected by gravity. Perhaps, (in my opinion) a non-baryonic dark matter bound to the celestial body, since this is transparent to light and can form a medium for light propagation, slowing and refraction which medium's density can be affected also by gravity?

      3. Since atomic clocks say one thing and pendulum clocks say the opposite, if time is perceived to flow, even if this is an illusion according to Paul Davies, a background 'illusory' time independent of device is required in physics. We may have to swallow the humble pie and return to Newton's Absolute Time.
