    No way Peter, you are wrong. It is _not_ gravity.

    You define gravity force as the force that follow the rule F=K*m1*m2/r^2.
    Enlighten me showing how centripetal forces follow that rule (mainly how
    you can accomodate the [m1*m2] term) !
    I don't remember general relativity enougth, but I'm sure that centripetal
    forces are _not_ comparable to gravity forces.
    Yes ... they can be used to simulate gravity forces, the same way you can
    use the acceleration of a car to simulate gravity force directed
    horizontally: acceleration ... this is the key ... gravity is a force that
    have a constant acceleration of 9.81 m/s^2 without motion between two
    bodies while centripetal forces need motion !
