Singularities in GR

  1. Nov 23, 2009 #1
    Singularities in GR are often associated with geodesic incompleteness.

    My question is what does it actually mean for a geodesic to be incomplete?

    From my vague understanding, geodesic incompleteness is when we can't extrapolate the function over all of space & time.

    yes but what about the t=0 big bang singularity. is this a singularity because we can only extrapolate geodesics as far back as to a time just after t=0 but we can't extend them to the t=0 region of spacetime itself and so the geodesics are incomplete?

    From what I understand of GR, yes.
