Matter is able to fall a light speed in black holes.
Really this is about the end of time. Falling at light speed goes
hand in hand with reaching the event horizon.

There is no relative time past the event horizon. The slowdown
of time around a collapsing object is absolute. A black hole
would be a timeless volume - there would be no time inside.
But you can't divorce time from space. If one goes then goes
the other.

I must paint a picture of unification which as much applies
to the begining of the universe as it does black holes:
Where time goes Everything (else) Goes with it.
No time = No space ; Can't divorce time from space
No time = No mass ; No mass without space-time
No mass = No gravity.

The End would be a complete unraveling of physics.

By Unification you cannot divorce any of the parts from the whole.
You would no longer have a whole.

Light Falls Everywhere...

The simplest understanding of the strength of gravity is by
considering it as an acceleration equivalent.
Gravity as an acceleration is limited to light speed.
Curved space-time has an intrinsic limited acceleration equivalent.

I didn't see anything testable in there. How about some math?

Acceleration(gravity)C

Using the earth as the standard the strength of gravity will not
diminish as fast (as GR predicts) for smaller objects. And conversly
the strength of gravity will not increase as fast for larger objects.

It's similar to relativistic addition of velocities: double
the mass(or density) and you do not quite double the strength
of gravity; Half the mass and the gravity will be slightly more
than half.
