maaaay-be...if that is what he indeed said, then he's a physicist after all, and I am not. But I got the impression from the class I took on special relativity that he's primarily known for explaining astrophysics very well to a lay audience, not for his own contributions. I could be wrong.
If what you say is so, it would be because of the effect of the enormous gravitational force on photons and other possible means of detection such as radio emissions . But afaik you would not be able to communicate with a spaceship or satellite that has gone into the event horizon as by definition it's the point of no return. Now, would an event horizon distort perceptions in its vicinity, yes: http://www.perceptions.couk.com/uef/imgs/eh-action.gif http://math-it.org/Mathematik/Astronomie/koordin.gif These images seem to be saying that. But not that you can test the theory by sending a probe into the event horizon, which is what I am hearing from you.
