    Testing quantised inertia on the emdrive
    http://arxiv.org/abs/1604.03449v1


    It has been shown that truncated cone-shaped cavities with microwaves resonating within them move slightly towards their narrow ends (the
    emdrive). Standard physics has no explanation for this and an error
    has not yet been found. It is shown here that this effect can be
    predicted by assuming that the inertial mass of the photons in the
    cavity is caused by Unruh radiation, whose wavelengths must fit
    exactly within the cavity, using a theory already applied
    successfully to astrophysical anomalies such as galaxy rotation where
    the Unruh waves have to fit within the Hubble scale. In the emdrive
    this means that more Unruh waves are allowed at the wide end, leading
    to a greater inertial mass for the photons there, and to conserve
    momentum the cavity must move towards its narrow end, as observed.
    The model predicts thrusts of: 3.8, 149, 7.3, 0.23, 0.57, 0.11, 0.64
    and 0.02 mN compared with the observed thrusts of: 16, 147, 9, 0.09,
    0.05, 0.06, 0.03, and 0.02 mN and predicts that if the axial length
    is equal to the diameter of the small end of the cavity, the thrust
    should be reversed.
