    How do you measure stationary?, you devise a method to detect motion and if you detect no motion then it is stationary, a null result is a negative result, they looked for motion and the result was negative, NO MOTION. dont try to trick us, earth shows no axial rotation.

    I have a question, and I consider myself not ignorant of physics.
    If there was an ether wind, would the speeds of both light beams NOT be equal when they reach the detector?
    My reasoning is thus: any velocity the light gains (or loses) due to the ether on the *outbound* leg would be lost (or regained) on the *inbound* leg, and therefore both beams would recombine at the same velocity on the final leg towards the detector. What am I missing? ty in advance.

      I suffer from the same doubt. The point might be in the fact that the orange path wouldn't be perpendicular, but a diagonal due to ether drag. And thus the orange time would be greater than the yellow one and not viceversa. Still, it's difficult to me to take solid conclusions out of this experiments since it assumes too many things, like for instance that all ether is like a solid moving at the same speed relative to the earth and ether currents are not possible. It doesn't prove to me that it also doesn't exist. Maybe it's just independent to light. But that conclusion already appeared in Maxwell's equations. I don't know. Not very clear to me this subject either.

      _"If there was an ether wind, would the speeds of both light beams NOT be equal when they reach the detector"_ - It is not the (end) speed of the light that is important, but the time it takes to travel the distances. Those times depend on the direction and magnitude of the aether wind. Think of the extreme case of the light speed equal to the aether wind speed, and work out how the results would be affected.

  • @aethermedball
    @aethermedball Год назад +1

    What about scalar waves and the hysteresis effect? Longitudinal magneto dielectric waves (LMD) have no mass and potentially travel billions of time the speed of light. Electrical theory has always held the notion that there must be a field that is undefined. Faraday ,Maxwell, Tesla, Eric Dollard, and even Einstein himself, postulated this must be the case. Relativity is a theory, not a fact. Longitudinal waves travel almost instantaneously over vast distances without breaking the law of conservation. Perhaps there is no light in free space. It only manifests itself when it is in contact with the Earths envelope.

  • @mathewmunro3770

    All the Michelson-Morley experiment proved is that either the speed of light is the same in all directions, or that if it varies, then length also varies such that differences in the speed of light in different directions are undetectable with an interferometer. The trouble is that people have leapt to the conclusion from this that there is no such thing as absolute rest, which leads to the twins paradox.

    • @renedekker9806
      @renedekker9806 Год назад +1

      _"The trouble is that people have leapt to the conclusion from this that there is no such thing as absolute rest"_ - no experiment has ever shown that absolute speed or rest is detectable. So that is not a leap to a conclusion.

In other words the STR is proven by practical fact millions of times every day. Exit ether.

    MAJOR MISCONCEPTION. The two distances were not identical, and it would have been impossible to get distances for the 2 mirrors within a fraction of a 600 nm wavelength. They did not actually line them up and see no interference. They saw an interference pattern, and they saw that the interference pattern did not change when the apparatus was rotated.

But that doesn't matter because the lines were gonna be different anyways; it's a matter of how much the aether would change the light pattern at different angles. Rad. Thanks!

    • @1965ace
      @1965ace 7 месяцев назад

      I agree with your point about the precision of the instrument but nonetheless by rotating the whole thing we should have seen a change in the phase shift and thus the pattern. Because we didn't see a change in the pattern the velocities did not change with the motion through the theoretical aether. I think the properties of the space medium are outside of what we know so what we observe is true but the assumption that mediums have the same properties is false. This leads to other assumptions like there is no absolute spacetime grid etc.

    @ToddDesiato 3 года назад

    The argument doesn't hold if Earth is the source of the aether, and it is being dragged along with it. Then the Earth is always stationary relative to the aether. The EM Zero-point field for example, is a field that is Lorentz invariant. You can't measure your velocity relative to it because the spectrum is complete and infinite. When it is doppler shifted, it still looks exactly the same to the detectors.

    Is it fair to say that the prerequisites for light propagation are e0 and u0?
    Also that e0, u0 are attributes of light medium, Aether?
    Also that c is a constant, only if u0 and e0 are constants. Any particle or solar plasma wind intruded into the vacuum-Aether space will change e0, u0 and c.
    Also that solar wind increases the permittivity e0, u0 and caused a permittivity, permeability gradient around solar that is created a velocity gradient to a passing light and hence bends it? That gravity bends light is coincidence or correlation but proof?

    Very interesting.
    I would disagree, though, with the "orange time" (at apx. 19:40) being 2d/C, as if the speed of light wasn't affected by the "aether wind" when travelling perpendicular to it, as if its "vertical" component remained the same.
    Let's compare the light to a wave that would grow as a circle around a single source, like when you throw a rock into a pool. Here, the pool would be moving to the left at a speed of V (the "speed of the wind"). Let's say we "drop the rock" where the axis intersect (point O). Let's call I(t) the point on the x axis where the "source" is located after time t. The radius of the circle made by the wave is R(t)=C.t, because the light (the wave) moves away from its source at a speed of C.
    When the light hits point D (the upper mirror), the triangle OID will have a right angle in O, it's hypotenuse is DI (length = R(t)) and its sides are OD (length d) and OI (length I(t)), so: d^2 +(V.t)^2 = (C.t)^2, hence t=d/sqrt(C^2 - V^2) and the total time is twice that.
    So really, one should compare C/(C^2-V^2) with 1/sqrt(C^2-V^2). The former is sqrt(C) times the latter, so it is indeed larger.
    If I'm not wrong...

      I totally agree that the decrease in time taken when light moving in the direction of aether wind will cancel out with an increase in time taken when light moving against aether wind. No matter how many years you run this experiment it will always give a null result.
      Also, if anybody bases any assumption on this experiment that light always moves at a constant speed regardless of observer's speed, then that assumption also false.
      We know that Einstien used this experiment to make this assumption for Special Relativity (SR), which means SR is also wrong.
      Like that there are a couple of more flaws in SR.

    Surely if the horizontal beam is being effected by the aether in one direction, that effect will be equally and proportionally cancelled out when it goes in the exact opposite direction with the return. Unless the aether suddenly changes as it's on the way back...
    I'm saying that it seems logical to conclude that if there was an aether effecting the lights velocity, you still wouldn't be able to detect it that way. The same goes for the vertical beam in your diagram.
    Meaning that with or without an aether, the beams should still meet back again at the same time.
    There is a question maybe too about sensitivity.
    Because the light moves so fast, the, or any effect, may not be visible at such short distances.

      I have watched that video you mentioned also. But to be honest with you, as soon as I see equations, I lose track of the logic chain.
      I understand that there could be differences when spinning the concrete block in that famous experiment, IF there was a moving aether. That it might vary in velocity between to and from the mirror. But because the speed of light is so fast, it seems possible and even likely, that the apparatus might not be sensitive enough to pick up these differences in velocity distortion anyway. That either way, it's likely to get a null result. That the speed of light appears constant and both beams should meet at the same time, to either cancel each other out, or both hit the sensor at the same time.
      I've seen two videos on this, one where both beams meet and hit the sensor, another video diagram/explanation, where they both meet together and nothing hits the sensor.
      Is there something in the maths video, which shows that the apparatus IS sensitive enough to pick up the speed of light if it was effected by a moving aether like medium?
      Doesn't the thickness or bandwidth of the light wave need to be smaller to get a more precise reading? Meaning that to the extent that the waves of said beams fluctuate, is at least the extent of your margin of error.

    I deduced that in the case of the interference experiment, with the interferometer in the horizontal plane, the light has exactly the same speed in all directions. This is because light (photons) is coupled with the mass density field of the earth. Field that leaves the substance of the earth and emanates in the space in the immediate vicinity. The coupling of light with the density field of the transparent medium is proved by Fizeau's experiment. Experiment that accurately verifies Fresnel's formula, called partial ether entrainment. Fresnel's formula is easy to find, without any relativistic metaphysics, if the density of light and the density of the environment and the density of the earth are added together. And it is not about the entrainment of the ether, but it is about the variation of the refractive index of the transparent medium, when it is moving (in translation) compared to the situation when it is at rest. The negative term in Fresnel's formula is due to the coupling of light with the density field of the planet. Because he is in solidarity with the planet.

    Both Michelson and Morley assumed that the speed of light is not altered upon reflection by a moving mirror. This critical error produced a small variation in the distance traveled by the light between mirrors in the rest frame of ether.

      Actually, no it didn't... in fact the Sagnac experiment did not line up with the experimental predictions of the aether hypothesis.... that is the interference should vary depending upon direction, not just motion itself.... It along with the many other experiments which did not align with aether hypothesis predictions is what brought about special relativity. In fact the Sagnac effect can be derived from special relativity.

  • @atheistaetherist2747
    @atheistaetherist2747 4 года назад

    I add some aether info as follows.
    (1) Google Demjanov's twin media (air & carbondisulphide) MMX done in Obninsk on 22 June 1970 which showed an aetherwind of 140 km/s min & 480 km/s max during a day (this was the horizontal projection of the background aetherwind which is approx 500 km/s south to north blowing approx 15 deg off Earth's spin-axis). This genius 1st order MMX was 1000 times as sensitive & accurate as the oldendays 2nd order MMXs.
    (2) The MMXs were never null.
    (3) The correct calibration needed to allow for length contraction caused by the aetherwind.
    (4) The correct calibration needed to allow for the Fresnel Drag of light by the air. Prof Reg Cahill explains.
    (5) All MMX's suffer a linear ever-growing fringe-shift that gets larger with each rotation. All MMXs that employ vertical fringes will detect this signal. This includes laser MMXs. Horizontal fringes do not suffer from this effect. Because at least one mirror has to be turned a little (horizontally) to give the desired fringes then this results in a difference in a beam's horizontal radius from the axis of rotation. Mirrors approaching the axis in effect eat waves/fringes, & mirrors going away from the axis in effect vomit waves/fringes, the eating equaling the vomiting, but in Michelson's & Miller's MMXs the non-symmetry of the beams resulted in non-equal eating/vomiting, resulting in a signal that was periodic in a full turn. The desired sought-for MMX signal (fringe shift) being periodic in a half turn. University MMXs will detect this signal if the MMX is rotated lots of times, because this signal is ever-growing, 100 rotations will give 100 times the signal that is gotten from 1 rotation. Stopping or slowing the rotation has no effect on this signal, ie it doesnt reduce this signal, the size of the signal depends only on the number of rotations, it is ever-growing. Michelson & Miller deducted this signal from their raw readings, to do so they assumed that it was linear, which it is, or, it should be, but their MMX was top-heavy & suffered from a changing lean (it floated in a mercury filled trough), plus their MMX had a sloppy pin (ie axis of rotation), hence their LEGFS was not always very linear (but that is another interesting story in its own right).
    (6) Secondly the Michelson Morley MMX, & the Morley Miller MMXs, suffered a spurious signal that was periodic in a full turn. This was because their mirrors were at two levels, hence some of their light beams had to angle up & later down. This then introduced a spurious signal (fringe shift) due to angle contraction of the mirrors in their apparatus, which changed the effective lengths of the angled beams. I call such angle contraction Esclangon angle contraction, as Esclangon is i think the first person to bring it to the attention of science (but he didn't mention that it must also happen in an MMX). EAC is due to Lorentzian Length Contraction of solids (which should be called FitzGerald LC as FitzGerald was the first to predict it) which is due to any change in the aetherwind blowing throo a solid (which changes the size/shape of solids)(because solids are held together by electric forces)(these forces being affected by the wind).

    But this doesn't cover the sagnac experiment results, and the fact that laser gyros in every single plane work.
    As for why this experiment failed, anyone who has studied black holes knows why - in aether based physics they believe that the sun "pull" the aether around itself in a "whirlpool", similar to the egosphere of a relativistic black hole.
    I have a lot more to learn on both sides, but they seem to think that gravity is the incompressible aether being "pulled" into the earth and speeding up as the volume decreases as you approach earth, explaining the behaviour of gravity decreasing with distance as expected.
    If you want to really disprove aether you need to do what nobody else seems to want to do and tackle sagnac.

    The science society at the time mistaken about Aether is wind can drift through and not attaches to matter or molecules.
    Armed with this mistake Michelson set out to design his interferometer expecting to measure Aether wind velocity to be equal or close to earth’s orbital velocity.
    However what Michelson & Morley get was a residual but orbital speed as I expected.
    That is because Aether attaches to matter, the interferometer including earth and move at equal speed, as if Aether didn’t exists but it exist.

    @yannisvaroufakis9395 Год назад

    This is yet another video misconstruing the matter. The experiment did not prove there was no aether, and Einstein himself said so. Indeed, Einstein said there must be an aether in order for space to have properties. The ball throwing example atop a moving train is not a proper analogy. A ball is not a wave. Why not do it with sound? If you did, you’d discover that the speed of sound is also independent of the speed of its source. The speed of the sound of a train whistle at a given location is the same regardless of whether the train is moving. The only difference is that the pitch become higher if the train is approaching and lower if it is going away. That’s the Doppler shift. The same goes for light. Speed remains the same, but the wavelength is shifted either towards the blue or the red. With sound, it is because the speed of sound is only a property of the medium that is disturbed and has nothing to do with its source. Take also the example of a Jet fighter. I once saw one pass overhead, and there was no sound at all, but a second after it passed, I heard the roar of its engines and a small sonic boom. The plane had outrun the sound of its own engines. If you measured the speed of the sound along the direction of the plane and perpendicular to it, it would be the same, notwithstanding that the sound in the jet’s direction of movement would be facing a “headwind” of like 1000mph. I’m baffled over the logic of the MM experiment. One more thing: modern physicists quietly acknowledge the aether; they just call it the quantum fields. We know, for example, that electricity and magnetism propagate along fields that exist. But does anyone know what an electric field or a magnetic field in a vacuum is made of? No one. It’s a vacuum. Nothing is there, or so it seems. If you consider that QF theory posits that matter and energy particles are vibrations, disturbances, in the underlying fluidic fields that permeate the universe, you can then start to say: wait a minute, maybe there is an aether, as Einstein himself said there must be. It’s just irrelevant to calculating the “absolute” speed of light, since there is no such thing as an absolute reference frame.

    M&M experiment "failed" because the aether in close to the earth is dense and not permeable. It also moves along with the earth. No aether wind to "see". The experiment should be performed far from earth where the aether is not as dense and compressed. The aether is pushed aside by matter but retains its position like a girdle on your body. The dense aether also is instrumental in causing the gravity that pushes us towards the center of mass of the earth. It also causes the casimir effect, but on a smaller scale.

Experimet care verifica cu precizie formula lui Fresnel, zisa de antrenare partiala a eterului. Formula lui Fresnel se gaseste usor, fara nicio metafizica relativista, daca se aduna densitate luminii si densitatea mediului si densitatea pamantului. Si nu este vorba de antrenarea eterului, ci este vorba de variatia indicelui de refractie al mediului transaparent, cand este in miscare (in translatie) fata de situatia cand este in repaus.

Would you explain this "strange" behaviour of the light? I could. There is an aether and it goes along the gravitational field of the massive objects like planets, suns, black holes ext. otherwise no one can explain the existence of a black hole because nothing can exist below the event horizon according to non aether theories.

    Michelson/Morley test is a bunk idea, when it comes to measuring aether wind, it's essentially similar to measuring electromagnetic radiation near the surface of the sun (you're overloaded with the sun's magnetic energy). The Earth is also a giant magnet; trying to measure an "aether wind" would be near impossible. If there is actually aether (an electromagnetic field that fills and makes up the universe), then it would be like the turbulence in water, from a massive spinning sphere; the surface of the sphere would be even layers of pressure, extending outward from the surface (if not from the center mass, in the case of aether).
    This is what you're seeing in the later of this video (here: ruclips.net/video/7T0d7o8X2-E/видео.html ); layers of electromagnetic pressure, extending outward from the surface.
    You would have to be outside the planet's turbulent field of aether, to actually measure aether wind.
