Kip Thorn dismissed the fact that objects would fall faster than light inside a black hole. He claimed they only reach light speed. But if they reach light speed at the event horizon how are they not going to be propelled faster by the even greater gravity inside a black hole?

No. Kip Thorn was making an excuse to preserve Black Hole theory. Let's say he is correct that matter reaches only light speed; still this is a violation of Special Relativity. Matter cannot reach light
speed according to Albert Einstein. If it did it would disappear from
time. Matter reaching light speed is what disproves Black Holes at
their event horizons because they violate Special Relativity.

The second excuse that might be made is that matter does not even reach (or fall to) the light speed limit that Kip Thorn suggested. But time ends at the event horizon for matter causing the theoretical redshift and blueshift of light to go infinite which is a nonsense as prediction for energy. Light's energy would go infinite by blue shift and zero by redshift at the event horizon. These predictions spell the complete failure of black hole theory.

For time to really end for matter it reaches light speed. The fact is
time ending and the matter reaching light speed go hand and hand again violating Special Relativity. So please give up your excuses Kip Thorn and everyone else.

Even Albert Einstein did not believe in black holes. Instead he tried
to make the collapsing star bounce back in theory. That was his
reaction.
