I was wondering about the forces inside the event horizon, they
suggested that there would be much less gravitational effect inside,
between the Event Horizon and the singularity, than the area surrounding
the  outside of the black hole.

I thought about this and am not sure about it, if a mass is moving in
one direction at a designated speed, (say light), for this mass to be
stopped and or pulled back does this need an equal and opposite or
greater force acting on it to stop it and prevent its escape?. 

In the case of an opposing force does it need to be equal to the
original force in order to cancel this original force out? thus neither
force would get anywhere because of the equalibrium created. -->> <<--

Because of this (equal and opposite) forces, I was wondering whether the
forces, i.e. gravitational, inside the event horizon or at the
singularity would be moving faster than light, in order to trap light
inside the Event Horizon? what do you think?

What about supermassive black holes, like at the center of the galaxy?
do they have even greater forces present in them, because of their size?

Thanks
