    Hi,

    I was reading about the "relativistic hall effect":

    http://phys.org/news/2012-05-hall-effect-relativistic-effects-mobile.html

    It shows an asymmetrical relativistic effect that should be able
    to be measured and thus determine the absolute direction of motion and
    also the velocity:

    http://phys.org/news/2012-08-effect-rotating-relevance-everyday-applications.html

    That link shows the relativistic hall effect of a flywheel translating
    at relativistic speeds while at the same time rotating on its axis
    radially to the direction of translation. If the flywheel is
    stationary there is no asymmetrical effect from the rotation, but if
    the flywheel rotation occurs during relativistic translation then the
    flywheel will undergo an asymmetrical Lorentz transformation, ie.
    length contraction and mass increase on the side of the flywheel that
    has a rotational velocity that increases with the translating motion,
    and length stretching and mass decrease on the side of the flywheel
    that has a rotational velocity that decreases with the translating
    motion. If a clock was put on one of the flywheel spokes, it should
    then count slower on the flywheel side that is rotating towards the
    direction of the translating motion. So if you have three of these
    flywheels like a 3axis gyroscope, you could use them as a 3axis
    relativistic translation detection device!

    cheers,
    Jamie

    Hi,

    Thanks, I figured I had an error in my logic somewhere.

    cheers,
    Jamie
