    Attiyah's Cosmological shift and Attiyah's law of galactic shift


    Preliminary Notices:
    1- Irrespective of the orientation of the plane of 'the orbit of the Earth around the Sun' to the galactic plane, it could be assumed, only for the sake of simplicity, that they are parallel.
    2- Although this theory talks about a proportion, it is intended to be qualitative rather than quantitative.
    3- Because this theory is intended to be qualitative rather than quantitative, therefore, irrespective of the cosmological galactic motions, if there is any, I prefer to ignore them and concentrate on the change of the relative positions of the Earth and the galaxy that is due to the motions of the Earth only.

    'Attiyah's Cosmological shift' theory

    1- Due to the persistent revolution of the Earth in its orbit around the Sun, and to its persistent rotation on its axis, there is always a continuous change in the relative motion of the Earth and each one of the galaxies.
    2- Due to the persistent change of the relative motion of the Earth and the galaxy, the galactic spectral lines experience Doppler shift.
    3- The Doppler shift which the galactic spectral lines experience is mainly due to the change in the Earth's velocity in its orbit around the Sun, and slightly due to the rotation of the very Earth on its axis, as well as its wobbling.
    4- Due to the relatively slight effect of both of the rotation of the Earth on its axis and wobbling, on the Doppler shift shown in the galactic spectral lines, this slight effect itself could be dealt with as negligible.
    5- The change of the frequency of the galactic spectral lines that show the Doppler shift which is due to the Earth's revolution in its orbit around the Sun is proportional to the change of the Earth's velocity in its same orbit around the Sun.
    *****

    I call the last statement (#5) :"The change of the frequency of the galactic spectral lines that show the Doppler shift which is due to the Earth's revolution in its orbit around the Sun is proportional to the change of the Earth's velocity in its same orbit around the Sun" as 'Attiyah's law of galactic shift.

    N.B.
    It is possible to utilize 'attiyah's cosmological shift' theory to check the exactness of Kepler's first law and Kepler's second law.

    Do you think, we astrophysicists are stupid? Of course, the measured cosmological redshift is corrected for the proper motion of the Earth and the Sun. Furthermore, Doppler shift due to rotation produces a redshift on the receding side and a blueshift on the approaching side. In the case of low spatially resolved spectroscopy, the net redshift due to rotation of the observed galaxy is zero, because both effects cancel out. The only effect one could observe is the broadening of spectral lines. In addition, there is no such effect for galaxies that are seen face-on.

    I address astophysicists because I consider that they are clever and brilliant.

    How does 'Attiyah's cosmological shift theory' account for the galactic redshift that greatly exceeds the galactic redshift that could be attributed to the Earth's revolution around the Sun ?.In other words, how does Attiyah's cosmological law interpret the observation of redshifts greater than the redshift that could be caused by a velocity not greater than the average orbital velocity of the Earth which is about 30km/second?

    As long as the redshift could be increased by the addition, and could be decreased by the subtraction, it is very easy to interpret that some galaxies can show a relatively very great redshift. Thus, the observations that there are galactic redshifts very much greater than what could be caused by the Earth's rotation around the Sun might be simply explained.
    The 'gravitational lensing' is the answer. In other words, the gravitational redshift is the solution. How?
    1- In general, the farther the galaxy, the greater the number of the galaxies between it and the Earth.
    2- The farther the galaxy, the greater the mass its spectral lines pass by in their way to the Earth.
    3- The greater the mass between the galaxy and the Earth, the greater the redshift of that galaxy.
    In general, the more distant the galaxy, the greater its redshift must be.
    Simply, the more distant the galaxy, the more the gravitational redshift it suffers.
    So far, the change of the frequency of the spectral lines of the galaxy is proportional to its distance from the Earth. In other words, the redshift of the galaxy is proportional to its distance from the Earth, because the mass of the galaxies in between the galaxy and the Earth is proportional to the distance between both.
    Of course, due to the fact that the original source of the galaxy's spectral lines are its stars, and due to the translational motions of the stars inside the galaxy itself, no escape, those spectral lines should suffer the Doppler effect before leaving the galaxy Earthward. In addition to, it is probable that due to the mass of the galaxy itself, it forms a cause for a gravitational lensing that could affect the redshift of its spectral lines themselves.
    In aggregate, in general, the farther the galaxy, the longer the series of the 'gravitational lensing' actions its spectral lines suffer in their way to the Earth. So, one can consider that the galaxies that the spectral lines of a distant galaxy pass by in their travel toward the Earth could be described as 'redshift-strengthening stations.
