Regarding David Abineri's questions:
A high school student asked about the speed of light escaping from just
beyond the event horizon of a black hole. Is the speed slower than c?
Yes *and* no. It depends on just how you propose to measure it. Like
*any* other light ray anywhere else in the universe, if a photon passes
by (or through?) any observer that photon will *locally* be observed to
travel exactly *at* speed c as it goes by. ///
