A question about equivalence principle

    Hi! How this paper relates to the equivalence principle?

    http://arxiv.org/pdf/gr-qc/0701084.pdf

    "in contrast to the situation with static gravitational forces, the effects of accelerative gee-forces on the internal observer are increased"

    The affects on the internal observer are the same regardless of whether the stasis chamber is being accelerated or subjected to an external gravitational field.

    Assuming the article is accurate (and on cursory review, it is), in both cases the internal observer would experience a magnified G-force.

    The paper says, that on Earth's surface "gravitational field on an inside observer is effectively dampened". Thus my question.

    I didn't read through section 3 before.
    There must be something wrong with Janca's math in that section.
    I would say section 3.1 is more accurate than 3.2. Obviously, they should both be the same.
