Side issue:
Ask this: What's the speed of light about a black hole?
What about E=m*c^2 THERE?

At the event horizon, c = 0, thus m=0, E=0.

Ask me, I've been there <G>

But you are well outside <G>.
BB is in Lintland.

Cliff:

Lightspeed in a vacuum has not been observed to change by a
gravitational field.

Who told you that one? Some nun again?
It can slow down in gravitational fields.

Lightspeed wouldn't be much of a universal
constant if it changed everytime it passed, or went through,

A bit of glass?

some geodesic in curved space-time.

Which is exactly what it can do ..... what did you think caused
gravitational lensing (depending on units & your perspective)?

What's peculiar, is that you didn't challenge Ivan's comment that c=0
at the event horizon, which is not correct.

Feel free to comment yourself <G>.

Is this an indication of
yet ANOTHER conceptual boo-boo on your part? LOL

I don't see where I'm actually required to ....

Want to try to help him out of some of his many misconceptions?
Try ... the nuns & Aristotle did a bad job on him I think.

Sounds like more nunsense to me.

What is the speed of light at the event horizon?
From whose perspective?
