derekmcd and robnissen ! Thank you both for your input. I would like to explain my logic. I'm making an attempt to understand, what holds or galaxy together. I have problems with the concept of black holes, in the area of escape velocity on 2 interactions, Gravity & electromagnetic waves. I also have problems with Dark Energy. As you might know, electromagnetic waves can not propagate through the event horizon and yet the gravitational waves can. In the past I noticed space-time differences only affected the energy difference of an electromagnetic wave, and not the velocity, according to the equation E=hf by Mr. Planck, from this I made an assumption( I know, you'll say stop, there.), but just for argument sake, let us say, electromagnetic waves with zero relative energy can escape a black hole( this keeps the velocity of light constant in our universe and keeps the black hole in the universe), the only way it could effectively have an effect out side the event horizon is for that wave to have an event with an object that has momentum Greater than the relative momentum it had when it was emitted, by colapsing its wave function, and contribute its energy, completing the photon, by rendering this energy, to this wave. Now let us suppose the same thing can happen to a gravity wave emitted from below the event horizon, what would be the effect on a gravity wave like this, traveling through our galaxy, would it simply have the same effect as gravity with an origin external to the event horizon or would it be different?<br /> Thank you for your time.
