Hey Mr. Neutralino: Might you proffer your expertise in these issues? Greg has introduced some factors that I hope you can shed some light on, you may form a platform, before I make my next effort. Frankly, Greg has introduced some factors that I'm not familiar with. Anyone wish to share some resolutions on these issues?
Best regards,

Beats me, Greg, I know of only one so called event horizon, and that there are misunderstandings regarding the absolute speed of light, relative to it.
How can Light waves that are directed outwards be moving 'backwards' inside the ball ?? I understand how the light waves are diverging see italics above, but can't 'picture' the converging. Does anybody understand this and can you elucidate it ?
"How can Light waves that are directed outwards be moving 'backwards' inside the ball?"
I don't know of any such backwards moving light relative to the issued horizon, Greg.
Don't you mean the beams from the flashlight are moving at the speed of light ?
Yes.
Gottcha ... LOL
What is this saying ... isn't it the same for all observers ?
In the issue at hand, the relative speed of light is exceeded at the optical horizon, as it relates to the location of the observer. So there's some apparent ambiguity, here.
Please explain the different horizons, if not you Rascal, then anyone ?? Neutralino ??
I know of only one optical/event horizon - that having to do with Hubble's law. The 'absolute' and 'apparent' horizons - I'm not sure how they're differentiated or what that means.
