## Main Question or Discussion Point

Let's say i state following things:

1) c decreases in gravitational field (Shapiro delay)

2) gravity travels at the speed of light

3) gravity is inner force

4) black holes do have gravitational effect

When light approaches event horizon, it's speed approaches 0, and inside black hole light can't escape. So how gravity can? We are in gravitational field, so gravity propagates faster then c by c + delta c where delta c is c change in gravitational field. Any ideas on the insight?
