    NOOOO!!!  Wrong!  This person should be castigated!
There is no physical singularity anywhere in your standard
large enough gravitating mass, at the initial time.  In a uniform
mass, things will collapse to a singularity first at the center;
the conditions defining the event horizon (the "edges") might
be observed by a synoptic observer in that light travelling outward
(the best possible escaping signal) here finally collapses into the
singularity and here finally recedes in a "hyperbolic" orbit,
most of its energy sapped and red-shifted as a distant observer
might see it.
    Consider that in a 3-spherical universe, everywhere is equally
"central"; and with any positive density (I believe) everything
becomes singular after the same lapse of time.
