This question is in context of the recent gravitational wave detection by aLigo. Apparently aLigo has detected the entire process, including the before merger, during merger, and aftermath of the completed merger.
My understanding is that two black holes should not be seen to be merging in finite time, as observed by a distant observer. Since nothing can reach a black hole's event horizon in finite time (as observed from outside), how did the two black holes cross each others' event horizons and form a merged black hole in finite time?
