Kip Thorne says the following in his book BLACK HOLES AND TIME WARPS,1994, page 417,
It may be "simple", but that explanation sounds flimsy at best...can anyone help me understand it? How did effect precede cause in classical general relativity or does this have some other origin? It sounds more like quantum mechanics of some sort.
Little attention was paid to the absolute horizon because of our cherished notion that an effect should not precede it's cause...When matter falls into a black hole, the absolute horizon starts to grow (effect) before the matter reaches it (cause). The horizon grows in anticipation that the matter will soon be swallowed...this seeming paradox has a simple origin. The very definition of the absolute horizon depends on what will happen in the future: on whether or not signals will ultimately escape to the distant universe...it forces the horizon's evolution to be teleological...
