A question about general relativity

  1. Feb 15, 2010 #1
    Would it be accurate to say that, according to general relativity, gravity is the "force" that is felt by an object as it is confined to the present, analogous to centripetal force; and, that as one decreases the rate of the passage of time, the effects of gravity become less and less noticeable until they ultimately cease, then, decelerating in time further, the force of gravity is reversed? In contrast, if one accelerates the passage of time, the gravitational force becomes markedly stronger. Thus, it appears as though gravity is a byproduct of time.

    Yes, gravity is an inertial force in GR.
    No. The force of gravity depends on the local change (gradient) of time dilation, not the absolute value.

    This illustrates the connection between time dialtion and gravity:
