Zer0, the escape velocity is determined by the gravity experienced at the launch site, and most likely by the topology of the mass responsible for the gravitation. As regards what happens to photons that cannot escape the event horizon of a black hole I can't tell you as I don't know. A member such as Halc or Origin should be able to help.
