Adding a little bit here:

Essentially, trapped light has no path the leads away from a
Black Hole and is bent back on itself leading to a point from
where it began - or nearly so.

Yes, the speed of light does not change. However, it's a matter
of perspective and reference frame: To the observer traveling
through a black hole or event horizon time travels as usual but
behind them the universe is seen to advance in age (and to it's
death?) as he looks backward out into space - traveling through
and then eventually passing over the event horizon (their
collected field of view would shrink as though looking through a
tube). But, to an outside observer, at some distance away, the
traveler appears to stick to the event horizon never reaching
their directed destination point.

This principle also allows forward time travel through a simple
(?) process of orbiting a black hole at close range and then
departing away from it.

Backward time travel may also be possible if the shape of the
black hole (neutron star) is that of a rapidly rotating cylinder
(near the speed of light) - one could then hypothetically enter
layers of older (wrapped up) space-time along paths parralell to
it's axis or rotation. This allows backward travel to the point
at which this hypothetical object was created.

The frequency of light does change as a result of a
gravitational field and is red shifted downward (loses
energy/changes color) as it travels outward and is blue shifted
(gains energy/changes color) as it travels toward a gravity
field. The degree to which it does this depends upon the
strength of the field.

Photons (light) can escape from a black hole through a process
called Hawking Radiation - thereby preserving thermodynamic
laws. As a result, Black Holes can shrink over time. The smaller
the Black Hole, the quicker the pace of decay and evaporation
rate - pop!
