- Marinov's Toothed-Wheels Measurement of Absolute Velocity of Solar System.
- J.P.Wesley.
- Weiherdammstrasse 24, 7712 Blumberg, West Germany.
-
- Abstract: Marinov reports measuring the absolute velocity of the closed
- laboratory using two toothed wheels mounted on the ends of a rotating shaft.
- Light incident on the first toothed wheel is chopped. As it arrives at the
- second toothed wheel later, due to the finite time it takes light to travel
- down the shaft, it is again chopped by the second toothed wheel. The amount of
- light that gets through measures the oneway time-of-flight velocity of light
- in the direction of the shaft. By directly comparing the results for beams
- travelling in opposite directions the absolute velocity is directly measured,
- v = ((c+v)-(c-v))/2. He reports the absolute velocity of the solar system as
- v = 360 +- 40 km/s, alfa = 12 +- 1 h, delta = - 24 +- 7 deg, in agreement
- with the results from the 2.7K cosmic background anisotropy and Marinov's
- coupled mirrors experiment. The errors he reports are consistent with his
- experimental setup and procedure.
-
- 1. INTRODUCTION
- It is of considerable importance to examine Marinov's claim(1):
- i) It contradicts SPECIAL RELATIVITY, which assumes the velocity of light is
- uniquely c fixed relative to the moving observer.
- ii) It provides an additional independent measurement of the absolute
- velocity of the solar system.
-
- Considering point i) above there exists considerable dissatisfaction with
- SPECIAL RELATIVITY already (2-7). It would also seem that the observations of
- Roemer and Bradley(8,9), the Sagnac experiment(10), the 2.7K cosmic
- background anisotropy(11), and the Marinov coupled mirrors experiment(12)
- give firm evidence that the velocity of energy propagation of light is, in
- fact, c fixed relative to absolute space. In addition, assuming absolute
- space exists, it would appear that a moving observer must see two wave
- velocities for light, the phase velocity and the velocity of energy
- propagation, and not simply a single unique wave velocity of light as is
- usually assumed(13). These two wave velocities need not have the same
- magnitude nor direction. It is, thus, very impotant to know if more
- independent experimental evidence is now available that can confirm the fact
- that the velocity of energy propagation of light is c fixed relative to
- absolute space.
-
- Considering point ii) above, presently the only two reliable determinations
- of the absolute velocity of the solar system are 1) the anisotropy of the
- 2.7K cosmic background radiation 2) the Marinov coupled mirrors experiment.
- (12).The 2.7K background anisotropy provides one place accuracy. The Marinov
- coupled mirrors experiment provides slightly better accuracy; although with
- little difficulty it can be readily improved to give two, three or even four
- place accuracy(14). The Marinov toothed wheel experiment provides still a
- third independent method for determining the absolute velocity of the solar
- system. He reports one place accuracy; but it would appear that with some
- minor improvements that two place accuracy might easily be obtained. It is of
- some interest to know the absolute velocity of the solar system to as great
- an accuracy as possible; as three place accuracy might provide the chance of
- detecting dark neighbours to the solar system.
-
- The primary purpose of this paper is to provide a short understandable and
- readily available description and critique of Marinov's toothed wheel
- experiment, Marinov's own account(1) being neither clear nor readily
- available. It is hoped that this presentation might encourage an independent
- repetition of this important experiment.

- 2. MARINOV'S EXPERIMENTAL ARRANGEMENT (1)
- Two toothed wheels consisting of 40 round holes of diameter b = 6 millimeters
- drilled equi-angular distance from each other at a radial distance R = 12 cm
- from the center of two circular steel plates were mounted on a common shaft d
- = 120 cm from each other as indicated in Fig. 1. The shaft was driven at the
- center by a variable speed motor, N revolutions per second. An Argon laser
- illuminated the holes on the entrance wheel. A silicon photocell detected the
- light passing out of the exit wheel. The entire apparatus was enclosed in a
- vacuum.

- 3.THEORY FOR ONEWAY TIME-OF-FLIGHT VELOCITY OF LIGHT
- Although the present paper is concerned with the direct measurement of the
- absolute velocity of the closed laboratory; and it is not concerned with the
- measurement of the oneway time-of-flight velocity of light; in order to
- develop the theory and to indicate how possible errors may be estimated it is
- convenient to first present the hypothetical example of how one might measure
- the oneway time-of-flight velocity of light.
-
- It might be thought that one need merely measure the oneway time-of-flight
- velocity of light in two opposite directions and by subtracting them obtain
- the absolute velocity of the laboratory. This is in principle possible; but
- in practice the experimental errors for the measurement of the one-way
- time-of-flight velocity in either direction are too large.It is only by
- balancing the two results directly in a Wheatstone bridge that significance
- can be obtained; and the absolute velocity of the laboratory can be
- measured.
-
- The rotating entrance wheel chops the light beam. The rotating exit wheel
- chops this signal again but at a later time dt, the time for a pulse of light
- to travel down the length of the shaft d. If the observed time-of-flight
- velocity of light in the direction of the shaft is c*, then
- dt = d / c* (1)
- If the time-of-flight velocity of light is fixed as c relative to absolute
- space, then
- c* = c - vd (2)
- where vd is the component of the absolute velocity of the laboratory in the
- direction of the shaft.
-
- The two wheels, being rigidly mounted to the same shaft, can be optically
- aligned by simply altering the inclination of the light beam relative to the
- axis of rotation. If the beam is aligned to achieve a certain intensity Io
- (chosen as one half of maximum intensity, Io = Imax/2, to optimize the
- sensitivity) when N = 0, then the intensity must change as N increases and as
- the alignment of the entrance and exit holes changes relative to the chopped
- light pulse. Ideally for square holes of width b that can be perfectly
- aligned the fractional change in intensity is simply proportional to the
- fractional mismatch created by the time it takes the light to travel between
- the two toothed wheels; thus,
- dI/Io = 2 db/b (3)
- where
- db = 2 pi R N dt (4)
- It may be readily appreciated that for round holes and including possible
- effects from diffraction and vibrations dI/Io, will be simply a linear
- function of 2 db / b, if dI / Io is small, as is the case. In general then
- Eq. (3) may be replaced by
- dI/Io = 2 K db / b (5)
- where K is some konstant of proportionality. If this constant of
- proportionality were desired, it could be measured directly or it could be
- estimated theoretically. Combining Eqs. (1), (4), and (5) then gives the
- oneway time-of-flight velocity of light as (15)
- c* = (K Io / dI) ( 4 pi R N d / b) (6)
-
- 4. THEORY TO FIND THE ABSOLUTE VELOCITY OF THE LABORATORY
- Marinov sent simultaneously laser beams in opposite directions through his
- toothed wheel apparatus which were detected by two independent photocells, as
- shown in Fig. 1. He measured the difference ddI in the intensities
- registered by the two photocells directly using a Wheatstone bridge for the
- outputs. Letting the two light velocities involved be
- c-* = c + vd and c+* = c - vd (7)
- Eq. (6) yields the component of the absolute velocity in the direction of the
- shaft as
- vd = (c-* - c+*)/2 = (ddI / dI- dI+)(4 pi K Io R N d / b) (8)
- where 2 ddI = I- - I+ = |dI-| - |dI+| and dI- and dI+ are the intensity
- differences registered in the two directions. It may be readily appreciated
- that to within a negligible second order error of the order of (ddI / dI)^2
- or (vd / c)^2 that
- dI- dI+ = (dI)^2 (9)
- where dI may be taken as the intensity when vd = 0 or as 2 dI = |dI-| +
- |dI+|. Combining Eqs. (8), (9) and (6) (for the case vd = 0) then gives the
- desired result
- vd = (ddI / dI) c (10)
-
- To double his sensitivity and to obviate certain possible errors in alignment
- of his apparatus Marinov employed the stratagem of measuring the change in
- intensity dI when the shaft was rotated in both senses. Because when N = 0
- the intensity Io was chosen as 1/2 the maximum intensity, Imax; the change in
- intensity was positive for one sense of rotation, and negative in the
- opposite sense. The effective intensity change that could be measured was,
- thus, doubled. The intensity change dI was then taken as
- 2 dI = |dI(clockwise)| + |dI(counter clockwise)| (11)
- Marinov used the same stratagem when measuring ddI, averaging the results
- for the shaft rotating in the two possible senses. If the intensities are
- broken down into Io, a part dI that depends merely upon the average velocity
- of light c(where vd may be regarded as zero), and a part that depends upon
- the absolute velocity of the laboratory ddI, then the four possible
- situations considered by Marinov experimentally are listed in Table 1. The
- observed intensity difference was thus
-
- Table 1. Four intensities involved in Marinov's toothed-wheel experiment.
- case direction
- a c + vd Ia = Io + dI + ddI
- b c + vd Ib = Io - dI - ddI
- c c - vd Ic = Io + dI - ddI
- d c - vd Id = Io - dI + ddI
-
- 4 ddI = (Ia - Ic) - (Ib - Id) (12)
-
- It was found to be impossible to align the apparatus so that the two beams in
- opposite directions were precisely equivalent. Thus in fact (Io + dI)a - (Io
- + dI)c = I' and (Io - dI)b - (Io - dI)d = I'' were not precisely zero. A
- residual constant error (I' + I'')/2 remained in the determination of ddI. It
- is clear that this assymetry could have been easily taken into account if the
- apparatus had been mounted on a turn table and turned through 180 deg to
- repeat the observations. Averaging the two results would have then removed
- this constant error. Since Marinov's equipment was righidly fixed to the
- earth and could not be rotated; he resorted to the following strategem:
-
- 5 TWELVE HOUR OBSERVATIONS TO DETERMINE THE ABSOLUTE VELOCITY OF THE
- LABORATORY
-
- Marinov placed his shaft in the north-south direction horizontal to the
- earth's surface. At the latitude of Graz, Austria, where the experiment was
- performed, as the earth rotated, the shaft moved on the surface of a cone
- making an angle of 47 deg with respect to the axis of the cone, which was
- parallel to the axis of the earth's rotation. Thus, Marinov had to merely
- wait 12 hours for the earth to rotate his equipment through 180 deg as far as
- the component projected onto the earth's equatorial plane is concerned. It
- was, therefore an easy matter to subtract off the constant error (I' +
- I'')/2, mentioned above, by making observations over 12 or more hours without
- changing any alignments.
-
- 6. DETERMINATION OF THE DIRECTION OF THE ABSOLUTE VELOCITY OF THE SOLAR
- SYSTEM
-
- Because the component of Marinov's shaft projected onto the earth's equitorial
- plane sampled all possible directions in this plane after 12 hours of
- observation, and because the component of the shaft projected onto the
- earth's rotational axis provided the remaining direction to be sampled;
- straight forward trigonometry provided the direction of the absolute velocity
- of the earth on the day observations were made.
- The absolute velocity of the solar system (ie the sun) was then obtained by
- simply subtracting off the earth's orbital velocity with respect to the sun
- (which was, in fact, only of the order of the error that he reports for his
- observations). The tangential velocity of the earth's rotation, which is less
- than the error Marinov reports, did not enter in due to the north-south
- orientation of the shaft of his apparatus.
-
- 7. DISCUSSION
- The final formula(10) for vd involves only the intensity differences ddI
- and dI. Only these two quantities need be examined to determine the random or
- experimental error. Is the error of 11% reported by Marinov reasonable? This
- can be best estimated by considering 4 dI/I, and 4 ddI / Io. The factor 4
- arises from the increased sensitivity due to two senses of rotation being
- used and due to the two directions of light travel being used. From Qu. (6),
- setting c* = c, the fractional value 4 dI / Io, according to the numbers
- provided by Marinov, where he estimated the value of K theoretically for round
- holes as 9/2, is
- 4 dI/Io = K 16 pi R N d / c b = 5E-3 (13)
- To obtain dI it was necessary to subtract separate readings on a
- galvanometer. Separate large readings on a galvanometer can be usually made
- to about 1% accuracy. Thus, the theoretical and the experimental estimate of
- the fractional error are roughly the same.
-
- The determination of ddI was quite different. Here the difference was
- measured directly on a Wheatstone bridge. Differences of the order of ddI =
- 1E-3 dI = 5E-6 milliamps could be measured. Since ddI/dI ,varying as vd/c,
- Eq. (10), is in fact, about 1E-3, as known from the 2.7K anisotropy(11) and
- the Marinov coupled mirrors experiment; the fractional errors to determine
- 4 ddI / Io and 4 dI / Io are comparable.
-
- The highest current Marinov recorded for Io was 21 milliamp; and the maximum
- difference associated with the difference ddI was about 6E-5 milliamps. This
- means a fractional intensity difference of 4 ddI/Io = 1E-5 was recorded.
- Others have also reported being able to measure such intensity differences
- down to a level of 1E-5 using electronic comparisons. From Eq. (10)the
- fractional error for vd / c is the sum of the fractional errors of 4 dI / Io
- and 4 ddI / Io. As estimated above each of these fractional errors are of the
- order of 1%; so Marinov's experimentally determined experimental error of 11%
- seems quite reasonable.
-
- It has been speculated that mechanical vibrations would make it impossible
- for Marinov to have obtained a positive result. Although it may be true that
- instantaneous mechanical distortions produced misalignments resulting in an
- instantaneous error of the order of 1E-5 in fractional intensity;
- observations were not taken instantaneously. Observations were averaged over
- a time span long in comparison to the period of any mechanical vibrations of
- interest. Even if vibrations of the order of 1E-3cm existed, the fractional
- error produced by holes of 0.6 cm would be much less than Marinov's reported
- error. It seems clear taht vibrations could not possibly have affected the
- results. And Marinov reports, consistent with this estimate, no difficulty
- with vibrations.
-
- It is difficult to imagine systematic errors that might have distorted
- Marinov's results. Since the apparatus was evacuated, no atmospheric effects
- could enter in. No temperature effects were involved, as there was no large
- time laps between the measurements of ddI and dI.
