also, is the red shift that is observed as a star collapses to a point caused by the light being "dragged back" or is the relative recession of the matter inside,away from the event horizon(towards the singularity), the actual culprit?
(i mean that from the perspective of the outside observer, the space inside the event horizon recedes at an ever increasing rate approaching speed c, which would seemingly cause an apparent redshift in the light. If there is not a limit to the wavelength, this redshifted light would eventually approach an infinite wavelength, causing the escaping photons to move on or close to a straight line instead of a well defined wavelength). is there any reason this is impossible?
